Offshore Wind Study

The Offshore Wind Study investigated the necessity, benefits and costs of requiring the electric distribution companies to conduct additional offshore wind generation solicitations of up to 1,600 megawatts (MW).

General Information

In 2018, Governor Charlie Baker signed into law An Act to Advance Clean Energy, Chapter 227 of the Acts of 2018, which required the Massachusetts Department of Energy Resources (DOER) by July 31, 2019 to study the necessity, benefits and costs of requiring the Electric Distributions Companies (EDCs) to conduct additional solicitations and procurements for up to 1,600 megawatts (MW) of additional offshore wind.  The legislation also directed DOER to evaluate the previous 1,600 MW solicitation under Section 83C and the associated procurement process and make recommendations for any improvements.

The DOER Offshore Wind Study is the result of both extensive stakeholder outreach and quantitative energy sector modeling.  Based on the analyses in our study, an additional solicitation of 1,600 MW will likely provide benefits for Massachusetts ratepayers in excess of the anticipated costs of the contracts as long as offshore wind pricing remains similar to the first 83C solicitation or continues to decline. 

Based on these findings described in more detail within the study, DOER recommends and will require the Massachusetts Electric Distribution Companies to proceed with an additional 1,600 MW of offshore wind generation solicitations. The study recommends that the additional solicitations take place in 2022 and 2024 in order to strike a balance between capturing cost effectiveness offered by later procurements while providing a steady pipeline of solicitations to spur and maintain economic development opportunities.

The additional time between the 2019 and 2022 procurements allows for DOER to solicit written comment and hold a technical conference to gather data on whether and/or how a solicitation for independent transmission should occur and, if warranted, issue a separate contingent solicitation for independent transmission prior to additional solicitations for offshore wind. The request for comment begins the process to gather information and data for a possible separate contingent solicitation for independent transmission.
