How-To Guides


Installing clean energy requires a general understanding of the equipment, costs, and approvals required for each clean energy technology. Here we provide a variety of guides from the Trust and our affiliates to help you decide whether and how to install solar and wind, navigate approvals and interconnection processes, and purchase green electricity.

Permitting and Approval Guides

Airspace Issues in Wind Turbine Siting
Wind turbine projects need to clear many hurdles before they can proceed to construction. One of the most important milestones in any wind project is securing a determination from the Federal Aviation Administration (FAA) that the project does not adversely affect air traffic or radar systems. This can be a complicated and uncertain process, and many projects have run into unexpected delays. The primer below explains how anticipate and avoid some of these conflicts, and how the FAA review process works.  Several case examples are presented.

MTC Interconnection Guide for Distributed Generation
The utility interconnection process is an essential step for any clean energy system installed as distributed generation (typically local, customer-installed systems). This guide provides an overview of interconnection requirements and links to many more resources.

DOER Renewable Energy and Distributed Generation Guidebook
The Massachusetts Division of Energy Resources (DOER) provides one of the most authoritative guides on Massachusetts permitting requirements for clean energy and distributed generation. You can use this guide to determine what permitting will likely be required for your project based on technology type and other considerations. Note that the interconnection section of this guide is currently being updated.
