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).

Notices and Updates

On July 28, 2020, DOER submitted a letter to the Joint Committee on Telecommunications, Utilities, and Energy (TUE) announcing the results of its investigation into independent offshore wind transmission. Materials related to DOER’s investigation into Offshore Wind Transmission, including stakeholder comments and materials from a technical conference held on March 3, are available below on this page.

Offshore Wind Study

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 Offshore Wind Study was published on May 31, 2019.

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.

Offshore Wind Transmission Investigation

The DOER Offshore Wind Study recommended holding a technical conference to investigate whether and/or how a solicitation for independent offshore wind transmission should occur under the authority in the 2018 Act to Advance Clean Energy. DOER hosted a technical conference and solicited two rounds of written stakeholder comment in order to investigate the costs, benefits, and risks of independent offshore wind transmission. Materials from this investigation are available below on this page.

On July 28, 2020, DOER submitted a letter to the Joint Committee on Telecommunications, Utilities, and Energy (TUE) announcing the results of its investigation into independent offshore wind transmission.
