Clean, Affordable Energy for New England

The Maine Power Express

The Maine Power Express (MPX), is a proposed 1,040 MW HVDC transmission line to be 100% buried underground in an existing energy corridor and underwater, directly to Boston, MA. MPX is a partnership of Maine Power Express, LLC (MPX,LLC), and Con Edison Transmission, Inc. (CET). Learn more about the project here

Clearway Energy Group (Clearway) is developing the County Line Wind (CLW) project. CLW is a proposed 630 MW wind facility to be located on working forestry lands in Aroostook County in northern Maine. 

MPX and Clearway have partnered to bid the CLW and MPX projects into the Massachusetts 83D Clean Energy RFP which calls for up to 20-year PPA for delivered renewable energy. The request for proposals was issued by the Massachusetts Department of Energy Resources and is currently still in progress. 

We strongly believe that the best solution for the ratepayers of Massachusetts is to combine elements of several of the Mass RFP bids, thereby maximizing benefits and minimizing risk for all parties. We stand ready to work with the Mass 83D Evaluation Team as a potential alternative to other New England proposals.

Massachusetts Clean Energy initiatives

Two large procurements are in progress to secure renewable energy contracts for Massachusetts, based on the recent Act to Promote Energy Diversity.

83D Renewables - This RFP called for projects up to 1100MWs for on-shore wind, large-scale hydro power, solar and other clean energy resources. MPX worked with Clearway on the County Line Wind proposal. Unfortunately, the Evaluation Team selected the Eversource/HQ Northern Pass project. Shortly thereafter, the New Hampshire Site Evaluation Committee rejected the Northern Pass permit application by unanimous vote. Subsequently, the Northeast Clean Energy Link (NECEC) was chosen to take its place. Both projects involve 100% Canadian Hydro on overhead DC lines, along new Rights of Way. Meanwhile, MPX and Clearway are pushing forward on the project and stand ready to negotiate with Massachusetts and/or other New England states to help meet their objectives. Pairing the CLW/MPX project with other wind and Canadian hydro projects will create the optimal mix of affordable, domestic resources with firming hydro. Read more here

83C Off-Shore Wind - This RFP called for off-shore wind only projects up to 1600MWs. This will undoubtedly saddle Massachusetts ratepayers with above-market, long-term energy contracts. The process didn't allow lower-cost on-shore wind projects to compete which is a major missed opportunity for the Commonwealth and New England to bring these resources to market.

existing

Currently, there are two existing wind farms located in Aroostook County:

  • The 42MW Mars Hill Wind Farm has been in operation since 2007. 
  • The 148MW Oakfield Wind Farm began operation in October 2015.

These projects demonstrate the ability to get wind farms sited, permitted and constructed in the area. 

Proposed

Southern Aroostook County is a prime location for the development of new wind resources.

  • NRG's CLW project is a proposed 630MW wind facility and the primary partner of MPX.
  • As of February, 2018, there is an additional 2400MWs of Wind in the ISO-NE queue in the area. 

These wind projects require new transmission infrastructure to connect to the grid. That's where MPX comes in.

Northern Maine, specifically, Aroostook County, is host to over 3000MWs of potential wind capacity, which could meet over 10% of New England’s average demand. The first wind project in Maine was installed on Mars Hill and the second largest project in Maine was recently commissioned in Oakfield. The University of Maine at Presque Isle was the first university to install a wind turbine and Northern Maine Community College offers the only Wind Power Technology program in the northeast. Aroostook County has made an investment and commitment to Wind and welcomes new projects with open arms. The County is exempt from Governor LePage’s recent Executive Order suspending wind permits and, as proposed in new legislation, will be the only expedited wind permitting area in the state.

The Maine Power Express development team is working with multiple wind developers in the area to deliver these wind resources to the northern DC Converter Station. Wind is an intermittent energy resource, sometimes the wind blows, sometimes it doesn't. To balance out the energy, pairing the wind power with hydro power can provide a consistent, reliable clean energy resource for New England.

New tie with new brunswick

The Maine Power Express development team has chosen the southern Aroostook area for the location of the northern DC Converter in order to collect the nearby wind resources as well as to create a new transmission tie with New Brunswick, which could carry up to 1000MWs of transmission capacity from Canada into Maine and New England. This would enable the delivery of new and existing hydro, wind and tidal resources to the MPX Switchyard and DC Converter to balance the domestic wind resources.
