Access Northeast

Access Northeast. Access Northeast was a major proposed natural gas pipeline expansion project designed to enhance energy infrastructure in the Northeastern United States. The project aimed to increase the supply of natural gas to utilities and power generators across New England to improve reliability and potentially lower energy costs. It was developed by a consortium of energy companies, including Eversource Energy, National Grid, and Spectra Energy, before facing significant regulatory and economic challenges that ultimately led to its cancellation.

Project overview

The primary objective was to expand existing pipeline capacity by upgrading and adding new segments to the Algonquin Gas Transmission and Maritimes & Northeast Pipeline systems. The project sought to deliver an additional 1 billion cubic feet per day of natural gas, primarily sourced from the Appalachian Basin and other North American supply regions. Key beneficiaries were intended to be local electric distribution companies and power generation facilities across states like Massachusetts, Connecticut, and Rhode Island. The initiative was framed as a critical response to the region's constrained pipeline capacity, which contributed to high electricity prices during peak demand periods, particularly in winter.

History and development

The project was first announced in 2015 by the sponsoring utility consortium. Its development coincided with a regional debate over energy security following severe price spikes during the polar vortex events of the early 2010s. In 2016, the project proponents filed an application with the Federal Energy Regulatory Commission (FERC). However, a pivotal setback occurred in 2016 when the Massachusetts Supreme Judicial Court ruled in a case involving Eversource Energy that a proposed financing mechanism, which would have charged electric ratepayers for the pipeline construction, was unlawful. This decision severely undermined the project's financial model and led to years of uncertainty and delays.

Technical specifications

The planned infrastructure involved significant modifications to approximately 125 miles of existing pipeline, including the addition of new compressor stations and pipeline loops. Key components included upgrades along the Algonquin Gas Transmission corridor in Connecticut, Rhode Island, and Massachusetts, and enhancements to the Maritimes & Northeast Pipeline in Maine. The project would have utilized advanced materials and construction techniques to increase pressure and flow capacity. It was designed to interconnect with several major regional systems, including those operated by Tennessee Gas Pipeline and Texas Eastern Transmission.

Regulatory and permitting process

The project required approval from multiple federal and state agencies. The lead federal regulator was the Federal Energy Regulatory Commission, which oversees interstate natural gas pipelines. The project also needed permits from the United States Army Corps of Engineers under the Clean Water Act, and consultations with agencies like the United States Fish and Wildlife Service regarding endangered species. At the state level, it faced rigorous review under laws such as the Massachusetts Environmental Policy Act and the Connecticut Siting Council regulations. The aforementioned 2016 Massachusetts Supreme Judicial Court ruling created a major regulatory hurdle by blocking the preferred cost-recovery method.

Economic and market factors

The economic rationale centered on alleviating basis differentials between the low-cost gas at the Henry Hub and higher prices in New England, which lacks sufficient pipeline connections to the Appalachian Basin. Proponents argued the project would save consumers billions of dollars on energy bills. However, the economics were challenged by the rise of liquefied natural gas (LNG) imports into terminals like Everett Marine Terminal and the growing competitiveness of renewable energy sources like offshore wind in the Regional Greenhouse Gas Initiative market. Shifting energy policies in states like Massachusetts and New York toward decarbonization also reduced political support for new fossil fuel infrastructure.

Environmental and community impact

The proposal faced intense opposition from environmental groups, including the Sierra Club and 350.org, which argued it would lock the region into fossil fuel dependency and undermine climate change mitigation goals under agreements like the Paris Agreement. Local community concerns focused on potential impacts from construction, such as disruption to conservation land, wetlands, and aquifers, as well as ongoing emissions from compressor stations. Proponents highlighted that increased gas supply could support a transition from older oil-fired plants and coal plants, potentially reducing certain air pollutants. The project's cancellation was seen as a major victory for the environmental movement in the United States and influenced subsequent energy infrastructure debates in the region.
