Champlain Hudson Power Express

The Champlain Hudson Power Express (CHPE) is a 339-mile (HVDC) transmission line project developed by Transmission Developers Inc., a subsidiary affiliated with the Group, to import 1,250 megawatts of hydroelectric power from in to . The route consists of two 5-inch-diameter submarine and underground cables extending from the at the , southward approximately 192 miles underwater through and the , with the remainder buried onshore to a converter station in . Construction commenced on November 30, 2022, following approvals from the New York Public Service Commission in April 2022 and an updated U.S. Department of Energy presidential permit in March 2024 authorizing the capacity increase from an initial 1,000 megawatts, with in-service targeted for May 2026. Proponents highlight the project's role in advancing New York's Climate Leadership and Community Protection Act goals by displacing generation, potentially powering over one million households and avoiding up to 37 million metric tons of emissions over its lifespan through low-cost renewable imports. However, it has faced criticism from environmental organizations over potential disruptions to endangered species like during Hudson River cable installation, impacts on aquifers from trenching, and the broader ecological costs of Quebec's upstream infrastructure, including alteration and effects on communities. Economic concerns include reliance on payments in lieu of taxes that may burden local governments and questions about long-term cost-effectiveness given New York's evolving energy market. Despite these debates, the project's progress underscores advancements in HVDC technology for integrating distant renewables into urban grids.

Origins and Proposal

Initial Concept and Proponents

The Champlain Hudson Power Express (CHPE) project originated as a proposal to construct a (HVDC) transmission line capable of delivering up to 1,000 megawatts of hydroelectric power from , , to , utilizing underwater and underground cables to minimize surface disruption. The concept emphasized leveraging Quebec's abundant, low-cost surplus—generated primarily from large-scale dams—as a reliable, dispatchable source to meet New York's growing demands and support grid stability, contrasting with more variable and inputs. Transmission Developers Inc. (TDI), the primary developer, publicly announced the initiative on , 2010, following initial development work that began around 2008. TDI, headquartered in , spearheaded the project as a private transmission developer focused on innovative HVDC infrastructure to interconnect North American grids with Quebec's utility, which committed to supplying the power under long-term contracts. At inception, TDI positioned CHPE as part of a broader "smart grid" evolution, aiming to transmit clean, firm energy over 339 miles from the U.S.- border near Hertel, Quebec, southward through , along the , and terminating in . The firm's leadership, including executives with experience in cross-border projects, viewed the route's water-based segments as advantageous for environmental permitting and reduced land use conflicts compared to overhead lines. Key early proponents included TDI affiliates such as Champlain Hudson Power Express, Inc., initially structured as a joint venture between TDI-USA Holdings Corporation (majority owner) and National Resources Energy, LLC, to secure financing and regulatory approvals. By 2012, TDI had forged a landmark agreement with Con Edison for power delivery into New York City, underscoring utility support for the project's role in offsetting fossil fuel reliance amid rising demand. Ownership later transitioned, with TDI becoming a portfolio company of Blackstone Inc., a major alternative asset manager that backed the venture's expansion to 1,250 megawatts to align with New York's clean energy mandates. This private-sector drive contrasted with traditional utility-led initiatives, prioritizing merchant transmission models to capitalize on arbitrage between Quebec's excess generation and New York's import needs without direct state subsidies at the outset.

Early Planning and Route Selection

The Champlain Hudson Power Express (CHPE) project originated from efforts by Transmission Developers Inc., a focused on transmission infrastructure, to hydroelectric power from Hydro-Québec's grid in to meet City's electricity demands. In March 2010, Champlain Hudson Power Express, Inc. and CHPE Properties, Inc. filed an application with the New York Public Service Commission (PSC) for a Certificate of Public Convenience and Necessity, proposing a 336-mile (HVDC) capable of delivering up to 1,000 MW from the Canada-U.S. border to a converter station in . This filing marked the formal start of regulatory planning, driven by the need for reliable, low-carbon baseload power amid 's growing urban load and goals, with initial engineering emphasizing HVDC technology for efficient long-distance transmission with minimal losses. Route selection began concurrently with the application, prioritizing a predominantly aquatic path to reduce terrestrial environmental impacts, land acquisition costs, and community disruptions compared to fully overhead or land-based alternatives. The proposed route crossed the U.S.- border underwater in near , proceeded southward along the lakebed for approximately 125 miles, transitioned to short overland segments using existing highway and railroad rights-of-way (e.g., along New York State Route 22 near ), and then followed the bed southward for about 180 miles to the terminus. This configuration leveraged navigable federal waters under the Clean Water Act, allowing burial in sediment with horizontal for land crossings to avoid wetlands and sensitive habitats. Early alternatives analysis, conducted as part of the PSC and U.S. Department of Energy (DOE) environmental impact statement (EIS) scoping initiated on June 18, 2010, evaluated multiple options including western Hudson River rail alignments, overhead lines paralleling existing infrastructure, and variant water routes. Land-heavy routes, such as those along the Hudson River Western Rail Line, were rejected due to higher risks of habitat fragmentation, electromagnetic field exposure near populations, and permitting delays from eminent domain needs, while aquatic burial was favored for its lower visual and ecological footprint, compatibility with HVDC cable burial depths (up to 50-100 feet in rivers), and alignment with federal navigation standards. By February 2012, a joint proposal refined the route through stakeholder settlements, incorporating minor adjustments like railroad right-of-way segments to bypass constrained areas, balancing technical viability (e.g., cable ampacity and thermal limits in water) against site-specific constraints identified in geotechnical surveys.

Regulatory and Legal Process

Key Approvals and Settlements

The Joint Proposal of Settlement filed on February 24, 2012, involved 13 parties, including state agencies, environmental groups, and the project developer, which recommended route modifications to avoid sensitive areas and the establishment of a $117 million environmental fund over 35 years to support habitat restoration in , the , and related waterways. This settlement addressed stakeholder concerns during the Article VII proceedings and facilitated subsequent approvals. On April 18, 2013, the Public Service Commission (PSC) granted a conditional Certificate of Environmental Compatibility and Public Need under Article VII of the Law, authorizing construction subject to conditions including powers for the developer and mitigation measures outlined in the 2012 settlement. The U.S. Department of Energy issued a Presidential Permit on October 1, 2014, allowing the international segment from into , following environmental review under the . In January 2018, the project developer signed a Project Benefit Agreement with the towns of Stony Point, Haverstraw, and Clarkstown, and the villages of West Haverstraw and Haverstraw in Rockland County, providing community investments, job preferences, and mitigation for local impacts along the route. The approved long-term contracts for 1,250 MW of capacity delivery to on April 14, 2022, enabling private financing and integration with the state's clean energy goals under the Climate Leadership and Community Protection Act. On May 18, 2023, the authorized the Astoria Converter Station in as a major project component, incorporating environmental safeguards. An amendment to the Article VII certificate, along with the Environmental Management and Construction Plan, was approved on June 20, 2024, refining route segments and construction protocols. The Champlain Hudson Environmental Trust, funded by the 2012 settlement, supports grants for habitat enhancement projects, with initial disbursements accelerating $12 million in protections by December 2021 through a committee including state and city representatives.

Opposition During Permitting

Environmental groups, including , expressed opposition to the Champlain Hudson Power Express during the New York Public Service Commission (NYPSC) review process, citing potential risks from sourcing additional hydropower from , such as incentivizing new dam construction in that could disrupt river ecology, boreal forests, and indigenous communities through flooding and contamination. withdrew its earlier support on November 18, 2019, highlighting the absence of binding commitments from to avoid new dams and arguing that evolving state renewable mandates, like the Climate Leadership and Community Protection Act, diminished the project's necessity in favor of local and development. Concerns over direct impacts to the ecosystem were raised by and the Center for Biological Diversity, which warned in October 2020 that burying the high-voltage direct current cable could disturb sediments containing polychlorinated biphenyls (PCBs), generate electromagnetic fields disrupting migration of threatened species like the Atlantic sturgeon, and overall harm aquatic habitats during installation. Indigenous groups, such as the Lac Simon Anishinaabe and Innu Nation, opposed the project through affiliated advocacy, pointing to historical dam effects including mercury pollution from reservoirs and loss of traditional lands and fisheries. Local communities in Rockland County, represented by mayors, city councilmembers, and three state senators, challenged the proposed route during public hearings, arguing it threatened historic sites, safety, and private property through takings. The Hudson 7 coalition voiced serious concerns about construction-related risks in filings to the NYPSC on , 2020. These objections prompted route modifications, including a 7.7-mile terrestrial segment to bypass Haverstraw Bay and $31 million in community compensation agreements in 2018. On economic grounds, the Independent Power Producers of New York (IPPNY), a for electricity generators, filed a final opposition brief with the NYPSC, contending the project was uneconomic and reliant on subsidies or regulated rates that would burden ratepayers by suppressing wholesale prices, accelerating retirement of existing plants, and deterring investment in unsubsidized renewables. IPPNY argued that New York's existing resource mix, including renewables, already met demands without importing low-cost that distorts competitive markets. Despite these challenges from environmental, local, and industry stakeholders, the project advanced through permitting with mitigations like a $117 million fund for restoration and monitoring.

Technical Design and Infrastructure

Transmission Technology and Capacity

The Champlain Hudson Power Express (CHPE) employs (HVDC) transmission technology, specifically utilizing voltage-sourced converter (VSC) stations that enable independent control of active and reactive power flows. This VSC-HVDC system, branded as HVDC Light® by , facilitates efficient long-distance power transfer with minimal losses compared to (AC) lines, making it suitable for the project's 339-mile route spanning submarine and underground segments. The bipolar configuration consists of a pair of HVDC cables, including an associated telecommunications line, designed to operate at 400 kilovolts (kV). The project's rated capacity is 1,250 megawatts (MW), sufficient to deliver approximately 10.4 terawatt-hours (TWh) of electricity annually, primarily from hydropower sources to . This capacity represents about 20% of City's and supports the integration of without requiring extensive grid upgrades at the receiving end. The submarine portion comprises roughly 190 miles of cables laid along and the , while the remaining 140 miles are buried underground, minimizing environmental surface disruption through techniques like horizontal . Converter stations at the endpoints—one in Hells Gate, , and another interfacing with in —employ four-quadrant control for bidirectional power flow and grid stability.

Route Details and Construction Methods

The Champlain Hudson Power Express spans 339 miles, consisting of two parallel (HVDC) cables, each approximately five inches in diameter. The route originates at the U.S.-Canada border near , and extends southward, with an initial underwater segment through exiting near Putnam Station. It then transitions to terrestrial underground routing along existing roads, utility corridors, and railroad rights-of-way across counties including , , , and Rockland, before re-entering the water for submarine placement along the bed, continuing through the , and terminating at a converter station in . The path incorporates approximately 192 miles of waterway segments (, , and Rivers) and 147 miles of terrestrial installation, designed to avoid environmentally sensitive areas such as habitat in Haverstraw and former industrial sites along the . Underwater cable installation employs specialized marine vessels, such as the cable-laying ship , to deploy and bury the cables in trenches typically 4 to 8 feet deep using shear plows or jet burial methods, followed by placement of concrete mattresses for protection against anchors and currents in the and Rivers. Target burial depths in and the average 6 feet where feasible, with adjustments for sediment type and water depth to ensure stability and minimize ecological disturbance. Terrestrial construction primarily utilizes open-cut trenching for 102 miles of direct burial, involving excavation, placement in conduits or direct embedment, and backfilling, with cables separated by distances up to 15 feet for electromagnetic and thermal management. Horizontal directional drilling (HDD), a trenchless technique, covers 77 miles to navigate obstacles like roads, canals, and rocky terrain without extensive surface disruption, particularly in areas such as Rockland County. Onshore burial depths generally range from 4 to 6 feet, though deeper profiles up to 15 feet may be used in high-traffic zones or where blasting is required for excavation. Cable splicing occurs at intervals, with protective conduits (e.g., 10-inch-diameter plastic) used in HDD segments to house the conductors.

Construction and Timeline

Project Milestones

The Champlain Hudson Power Express project marked its formal entry into the construction phase on November 30, 2022, with initial groundwork commencing in Whitehall, New York, following the New York Public Service Commission's approval earlier that year. Construction on the converter station in , began on September 19, 2023, building on prior site preparations and representing a critical step toward integrating the 1,250 MW (HVDC) transmission into City's grid. Marine cable installation advanced significantly starting in August 2024, with laying operations in the Upper progressing toward completion by November 2024, followed by burial and protection phases across , the , and the . By July 2025, project teams completed successful testing of over 130 circuit miles of HVDC cables, validating system integrity ahead of final integration. In August 2025, the final cable stretch was laid in Lake Champlain, entering the project's closing marine and terrestrial phases, including ongoing burial in New York State waterways. As of September 2025, the converter station reached 96% completion, with mechanical finalization slated for fall 2025, alongside the Astoria-Rainey duct bank installation concluding major works by year-end. Terrestrial progress included near-completion of trenching (over 102 miles at 99%), horizontal directional drilling (77 miles at 99%), and wire pulls (530 at 95%), with Rockland County horizontal directional drilling finished and 80% of dig-lay-backfill done since July 2024. The project is targeted for in-service operation in mid-2026, specifically May 2026, delivering clean hydroelectric power from to upon commissioning.

Delays and Technical Challenges

The anticipated in-service date for the Champlain Hudson Power Express was adjusted in August 2022 from late 2025 to spring 2026, primarily due to an extended regulatory review process and supply chain constraints impacting of critical construction materials. By September 2025, project updates indicated that construction remained aligned with the revised timeline, targeting operational commencement in May 2026, with over 99% completion of trenching and horizontal phases. Technical hurdles emerged during preparatory testing, such as a 2022 pump study where software failures postponed trials from September 7 to September 9, resulting in a two-day delay; subsequent jet plow positioning issues, resolved after a two-hour interruption, were exacerbated by hard substrate conditions including rocks and timbers that necessitated blade modifications and a temporary operational pause. Construction logistics in densely populated areas posed ongoing challenges, particularly in Rockland County along the Route 9W corridor, where a projected 22-month work period has generated severe , business revenue losses, and resident disruptions characterized by U.S. Representative as a "quality-of-life catastrophe" warranting state and project compensation. These issues, including uncoordinated roadwork and indefinite segment timelines, have amplified local opposition without derailing the overall project schedule per developer reports.

Economic Impacts

Projected Benefits and Job Creation

The Champlain Hudson Power Express (CHPE) project is projected by its developers to generate approximately 1,400 family-sustaining union jobs during the construction phase, primarily in New York State, with total compensation estimated at $630 million over the build period. These positions are anticipated to support local economies along the 339-mile route, including roles in engineering, manufacturing, and installation of high-voltage direct current (HVDC) infrastructure. Proponents, including Transmission Developers Inc., further estimate broader employment impacts exceeding 2,000 jobs when accounting for indirect and induced effects from supply chains and vendor activities. Economic benefits are forecasted to include $3.5 billion in overall value to New Yorkers, encompassing reduced costs, enhanced grid reliability, and fiscal inflows. Local governments across 73 localities and 59 school districts are expected to receive $1.4 billion in new tax revenues over the project's operational life, derived from property taxes on converter stations and related facilities. A macroeconomic analysis commissioned by project supporters projects additional state-level output from construction activities, though critics note that such estimates rely on assumptions about labor multipliers and may overstate net gains if offset by displaced in-state renewable investments. Beyond direct job and revenue projections, the $6 billion investment is positioned as a catalyst for long-term economic resilience by enabling access to 1,250 megawatts of hydroelectric capacity, potentially stabilizing wholesale electricity prices in . New York state officials, including Kathy Hochul's administration, have highlighted the project's alignment with clean energy goals while emphasizing its role in job creation without specifying independent verification of the 1,400-job figure beyond developer models. These projections assume full utilization of the line's capacity and stable hydroelectric imports from , factors subject to market and regulatory variability.

Market Effects and Fiscal Criticisms

The Champlain Hudson Power Express (CHPE) project integrates into New York's primarily through the state's Tier 4 Credits (RECs) program, delivering up to 1,250 MW of hydroelectric power from to at strike prices beginning at $97.50 per MWh and escalating to $176.36 per MWh over 25 years. These rates significantly exceed prevailing New York City Locational Based Marginal Prices (LBMPs), which averaged $39.12 per MWh year-to-date as of December 2023, potentially distorting wholesale markets by introducing subsidized high-cost supply that suppresses competitive pricing signals and discourages unsubsidized generation investments. Independent analysis by the Independent Power Producers of New York (IPPNY) describes the project as "grossly uneconomic," arguing it cannot achieve profitability as a merchant line without out-of-market subsidies, which could further undermine the state's competitive market framework by favoring imported power over domestic resources. Market effects include elevated Locational Capacity Requirements (LCRs) in due to the added import capacity, which may drive up system-wide capacity costs as the project displaces existing generation and alters dispatch patterns, potentially leading to higher upstate prices from constrained transmission and reduced local output. While proponents forecast wholesale savings of $17.3 billion over 30 years through increased clean energy supply, critics contend these projections overlook the and long-term lock-in of elevated costs, risking inefficient in a market already strained by policy-driven retirements of reliable baseload capacity. The reliance on Hydro-Québec's , sold at a markup to exploit New York's higher prices, exemplifies causal distortions where geographic benefits the exporter while imposing opportunity costs on importers, including foregone investments in lower-cost domestic alternatives. Fiscal criticisms center on the project's estimated $6 billion total cost, financed privately but underwritten by ratepayer-funded mechanisms that socialize expenses across New York while concentrating benefits in New York City. The Tier 4 REC subsidies equate to an average 2% increase in electricity bills statewide—approximately $2 per month per household—transferring risk from developers to consumers without commensurate emission reductions, as the imported power may merely offset rather than supplant fossil generation elsewhere in the system. Additional burdens arise from property tax exemptions and Payments in Lieu of Taxes (PILOTs), such as $105.48 million over 30 years in Dutchess County alone, which reduce local revenues and shift fiscal loads to other taxpayers, a practice critiqued as a "grift" that underdelivers compared to standard ad valorem taxation. Proposals for direct public funding, such as those floated by former Mayor to cover portions of the line's construction exceeding $3 billion, highlight risks of taxpayer exposure in an otherwise private venture, exacerbating inefficiencies in a policy environment prioritizing imports over market-driven solutions. Overall, these fiscal arrangements prioritize environmental mandates over cost minimization, locking in premiums that could total billions in foregone savings, with poised to realize $15 billion in U.S. revenues over 25 years from the deal.

Reliability and Environmental Considerations

Power Source Dependability

The power source for the Champlain Hudson Power Express is generated by , Quebec's utility, which operates over 60 hydroelectric stations with a combined installed exceeding 37 gigawatts, predominantly from -based facilities enabling dispatchable output. This system has supported electricity exports to the for decades, positioning as a consistent supplier with firm contracts, including the 1,250-megawatt allocation designated for the project. The storage allows for seasonal balancing, achieving effective factors around 60-70% and reducing vulnerability to daily fluctuations compared to non-storage renewables like or . Despite this, Hydro-Québec's supply dependability faces pressures from Quebec's rapidly growing electricity demand, driven by , data centers, and industrial expansion, which the utility forecasts will necessitate 150-200 additional terawatt-hours of generation by 2050 to avoid net-zero shortfalls. Provincial analyses indicate shortages persisting for up to a , prompting a $185-billion, 12-year capacity expansion plan targeting 9,000 megawatts while addressing outage risks. During events, such as cold snaps, exports have been curtailed to prioritize domestic needs; for instance, in the January 2023 Arctic blast, Quebec's system strained under record demand, highlighting limits to uninterrupted cross-border delivery. System-wide reliability metrics underscore both strengths and episodic weaknesses, with Hydro-Québec's unadjusted System Average Interruption Duration Index (SAIDI) for rising in 2023 due to an intense but improving markedly in 2024 through targeted interventions like AI-driven vegetation management. Overall, these indices place Hydro-Québec among Canada's more reliable utilities, though higher than peers like in outage frequency during weather extremes, reflecting hydroelectric infrastructure's exposure to icing and precipitation variability. For export-dependent projects like CHPE, this implies robust baseline availability tempered by contractual safeguards against curtailment, yet contingent on Quebec's ability to expand generation amid climate-driven hydrological uncertainties.

Emission Claims and Local Ecosystem Effects

Proponents of the Champlain Hudson Power Express (CHPE) project, including developer Transmission Developers Inc., assert that the transmission of 1,250 MW of hydroelectric power from will displace generation in , yielding an annual reduction of approximately 3.9 million metric tons of CO2-equivalent emissions, comparable to removing 44% of passenger vehicles from NYC roads. This projection assumes the imported power replaces peaking plants, which currently supply a significant portion of NYC's during high-demand periods, thereby avoiding emissions from . Critics, including the Independent Power Producers of New York (IPPNY), a representing non-hydro renewable and gas interests, contend that these emission reductions are overstated or illusory. A 2020 IPPNY-commissioned analysis argues that CHPE power would primarily displace existing zero-emission sources like , , , and measures rather than fuels, given New York's decarbonization trajectory under the Climate Leadership and Community Protection Act, resulting in negligible net GHG savings. Additionally, lifecycle assessments highlight that Quebec's large-scale hydroelectric reservoirs, particularly in regions, emit from decaying , with emissions persisting over decades rather than diminishing as maintains; these factors reduce the of imported hydro over New York's gas peakers when full supply-chain impacts are considered. Local effects during construction include temporary disturbance from trenching and cable laying in the and , potentially mobilizing contaminants in historically polluted sediments and affecting benthic habitats. The U.S. Department of Energy's 2021 Supplemental Analysis to the identifies risks to and aquatic from suspended sediments, though measures such as curtains and seasonal timing (e.g., avoiding sturgeon spawning) are proposed to limit duration to weeks per segment. Environmental groups like the Center for Biological Diversity warn that such activities could harm critical habitats for endangered in the , a vulnerable to riverbed disruption, with federal regulators urged in 2020 to scrutinize cumulative impacts amid ongoing cable installations. Operationally, the submarine HVDC cables generate electromagnetic fields (EMF) and localized heat, with thermal modeling indicating temperature rises of up to 5–10°C in sediments near the cables during peak load, potentially altering microbial communities and behaviors in the riverbed. Studies cited in project filings suggest minimal effects on migratory like due to DC EMF's lower induction compared to AC systems, but concerns persist regarding in food webs and facilitation of spread via construction vessels. Federal and state reviews, including the 2014 Final EIS, conclude overall impacts are not significant after , though independent ecologists emphasize uncertainties for Lake Champlain's oligotrophic , where cable crossings could subtly shift nutrient dynamics or fisheries.

Controversies and Stakeholder Views

Environmental Group Critiques

has opposed the Champlain Hudson Power Express, arguing that horizontal for the underwater cables could disturb contaminated sediments in the , potentially releasing toxins and harming fish populations and . The organization contends that such installation methods risk resuspending legacy pollutants accumulated from industrial activities, exacerbating ecosystem stress in the river's sensitive habitats. Riverkeeper further critiques the project for potentially driving expanded hydroelectric development in , which could lead to additional dam construction, reservoir-induced , and displacement of communities, outweighing purported climate benefits for . The group advocates prioritizing local renewable sources and efficiency measures over imported power, viewing the as misaligned with sustainable regional energy strategies. The 's Atlantic Chapter has similarly rejected the project, characterizing it as a "private roadway" enabling to export power profitably while limiting New York's control over its energy mix and yielding minimal permanent jobs—only 26 projected. emphasizes that large-scale dams supply the , raising doubts about net climate advantages due to upstream flooding, , and releases from reservoirs, alongside ongoing indigenous resistance in . Other groups, including the Center for Biological Diversity, have echoed warnings about the line's , particularly potential effects on aquatic species during operation and from land-based segments. These critiques highlight tensions within environmental advocacy, where immediate access to low-carbon power competes against localized and upstream environmental risks.

Industry and Economic Opposition

The Independent Power Producers of New York (IPPNY), a representing power generators, filed a final brief with the Commission in opposition to the Champlain Hudson Power Express (CHPE), arguing that the project is grossly uneconomic and requires substantial subsidies to achieve profitability. IPPNY contended that these subsidies, structured through out-of-market contracts, would suppress wholesale prices below efficient levels, potentially forcing the premature retirement of economically viable existing generation plants and chilling in competitive projects. Merchant generators further criticized CHPE for lacking reliable winter deliverability, asserting that the line would provide primarily during summer months despite a 25-year , undermining its value for addressing New York's shifting toward winter. Major New York consumers joined this opposition, highlighting risks to market competition and reliability, with estimates from intervenors suggesting a potential 5.7% increase in statewide bills in the first year of operation due to subsidized imports bypassing in-state resources. Economically, opponents emphasized that CHPE's reliance on Tier 4 renewable energy credits (RECs) imposes costs on ratepayers, with REC prices starting at $97.50 per MWh and escalating to $176.36 per MWh over 25 years—rates 2.5 to over 4 times prevailing New York City locational based marginal prices of $33.67 to $39.12 per MWh. This structure, critics argued, transfers above-market costs to consumers through regulated rates, offsetting any purported job creation benefits (such as the projected 1,400 positions) with broader fiscal burdens and reduced incentives for efficient domestic generation.

Expected Outcomes and Future Role

Operational Projections

The Champlain Hudson Power Express (CHPE) is projected to enter commercial service by the end of May 2026, following construction commencement on November 30, 2022, and ongoing activities including submarine cable installation in scheduled for late 2024. Upon operation, the 339-mile (HVDC) transmission line will deliver up to 1,250 megawatts (MW) of hydroelectric power from Hydro-Québec's facilities in to New York City's Zone J load area, equivalent to the output sufficient for approximately one million average homes. Grid modeling by the New York Independent System Operator (NYISO) anticipates CHPE enhancing installed capacity margins in the downstate region starting in 2026, with contributions modeled as dispatchable imports up to the full 1,250 MW capacity during peak demand periods, though actual utilization will depend on contractual arrangements with Hydro-Québec and real-time grid needs. The project's HVDC design enables efficient long-distance transmission with minimal losses, projecting operational reliability aligned with hydroelectric source availability, which NYISO assessments treat as firm capacity given Hydro-Québec's historical performance in supporting imports.

Integration with Energy Policy

The Champlain Hudson Power Express (CHPE) supports New York's Climate Leadership and Community Protection Act (CLCPA), enacted in 2019, which requires 70% renewable electricity generation by 2030 and 100% zero-emission electricity by 2040. The project delivers 1,250 megawatts of hydroelectric power from to the load zone, enabling the state to procure out-of-state renewable energy credits under the Clean Energy Standard's Tier 4 program, specifically designed for large-scale renewables serving high-demand urban areas. In April 2022, the New York Public Service Commission approved a long-term Tier 4 for CHPE, positioning it as a key infrastructure element to bridge gaps in domestic renewable capacity amid accelerating and load growth driven by CLCPA mandates. CHPE's integration addresses reliability challenges in policy compliance, as highlighted by the New York Independent System Operator (NYISO), which projects potential capacity shortfalls in the zone without timely transmission additions like this 330-mile line, scheduled for operation in spring 2026. Proponents, including project developer Transmission Developers Inc., estimate it will provide over 15% of the remaining generation needed for the state's 2030 renewable targets, displacing fossil fuel-based peaking plants and supporting grid stability during . This aligns with CLCPA's emphasis on diverse clean energy imports to supplement in-state , and storage procurements, which face siting and constraints. Critics, including the Independent Power Producers of New York, contend that CHPE's emissions benefits are overstated for CLCPA compliance, arguing that importing power from Hydro-Québec's existing dams—without guaranteed new low-carbon capacity—may not yield net greenhouse gas reductions, as it could offset other renewables or natural gas in Quebec's system rather than curtailing fossil fuels in New York. Despite such analyses, New York regulatory frameworks treat certified Quebec hydropower as qualifying renewables for Tier 4 obligations, facilitating compliance credits while NYISO models underscore the project's role in averting reliability violations under aggressive decarbonization timelines. Ongoing Public Service Commission proceedings continue to evaluate such transmission projects for alignment with CLCPA's economic and environmental criteria.
