Joint Powers Agreement

In July 2017, Cape Light Compact reorganized as a Joint Powers Entity (JPE), under the Act Modernizing municipal Finance and Government that was enacted in 2016 by the Legislature. This Act allows governmental units to enter into a joint powers agreement for the delivery of regional services. All of the Cape and Vineyard’s 21 towns and Dukes County are members of the Cape Light Compact JPE, under the Joint Powers Agreement, amended and restated on July 21, 2021.

The JPE is its own separate legal public entity, which can perform administrative and financial functions; including, but not limited to, contracting with third parties to apply for and receive grants; receive and expend funds, and hire employees.

Some elements of the JPE:

  • Board of Directors appointed by their towns’ appointing authority
  • Enhances financial accountability by:
    • Requiring independently audited financial statements
    • Treasurer functions are performed by a separate entity
    • Annual reporting requirement to the Massachusetts Department of Revenue
  • Offers express liability protection for its members regarding liabilities associated with JPE employees and programs.

The Compact has put together some FAQs that have more information.

Aggregation Plan

The Aggregation Plan is a document required by state law that describes a dozen key items such as the structure of the program, purposes, funding, etc. Massachusetts Department of Public Utilities (DPU) approval of an Aggregation Plan is required for start up of a municipal aggregation program for electric customers. The Compact’s original Aggregation Plan was approved by the DPU in August 2000 following a process of planning with the state Division of Energy Resources and the DPU, and local public hearings. The Aggregation Plan was previously viewed as a formation period document, however, the DPU has utilized the Compact’s Aggregation Plan as a model for other municipalities seeking to form their own aggregation and suggested the Compact consider updating the document in 2013.

CLC asked by DPU to consider revising aggregation plan

On 8/27/13, the DPU sent a letter to the Compact asking us to review our plan to:

  • Determine whether the Compact should file a revised Aggregation Plan to reflect current structure and operations;
  • Consider removing obsolete terms and references; and
  • Comply with any applicable laws, regulations and DPU precedent and the forthcoming decision in DPU 12-124 (Lowell Aggregation Plan).

At the 9/11/13 Compact Governing Board (“Board”) meeting, the Board created the following process to comply with this request.

  • Inform Compact Member towns/counties and public of the Compact’s intent to review and possibly update Aggregation Plan
  • Have Compact staff and legal counsel to review the Aggregation Plan and propose revisions for Board consideration
  • Consult with Department of Energy Resources (DOER) on Updated Aggregation Plan
  • Hold a Board vote to release proposed Updated Aggregation Plan for public review
  • Open a public comment period on the proposed revisions/updates of the Aggregation Plan
  • Hold a Board vote to adopt Final Updated Aggregation Plan after public comment period ends
  • Submit Final Updated Aggregation Plan to DPU

On 10/30/13, the DPU sent a letter to the Compact affirming that the Compact may continue operating its municipal aggregation program, including solicitation of bids for energy supply.

At the 12/11/13 Board meeting, the Board voted to release the proposed Updated Aggregation Plan for public comment and to hold 3 public information sessions. Public information sessions were held on the proposed revised plan on:

  • January 15, 2014, at 7pm at the Mashpee Public Library
  • January 16, 2014, at 7pm at the Orleans Town Hall
  • January 30, 2014, at 5:30pm at the Oak Bluffs Library *rescheduled date due to storm on 1/21*

Cape Light Compact received public comments through February 7, 2014. Over 60 letters of support were received from member towns, businesses, institutions, residents, non-profit organizations and elected officials.

On 2/26/14, the DPU sent a letter to the Compact stating that they wish to have a revised municipal aggregation plan filed no later than 4/4/14, in order for them to review the plan in a timely manner.

On 5/14/14, the DPU held a public hearing on the revised Aggregation Plan at Mashpee Public Library.  Elected officials, leaders of organizations and consumers from across the Cape and Martha’s Vineyard spoke about the Cape Light Compact’s benefits to the region. More than 75 people attended. There was overwhelming support for the updated plan to be expeditiously approved.
