MPUC Clarifies Standards for Interconnection of Small Generators

In response to two complaints, the Maine Public Utilities Commission has issued an order clarifying Chapter 324, Small Generator Interconnection Procedures.  Chapter 324 was created to provide uniform standards for the connection of small generators to the electric grid in Maine as a result of increased interest in distributed generation.   The standards in Chapter 324 are an attempt to reduce transaction costs for small generators, allocate interconnection costs between the generator and the utility, set certain technical standards and create predictable outcomes.   

The Commission’s March 16, 2011 Order Regarding Implementation of Interconnection Rules (Ch. 324) clarifies that utilities must provide a “detailed engineering analysis” to an interconnecting customer, so that the customer has a clear understanding of what electrical upgrades may be needed to accommodate the generator before the generator is charged with the costs of upgrades.  In some circumstances, the customer must also be advised of the customer’s right to bring a dispute to the Commission for resolution pursuant to Chapter 324.
