Effective August 3, 2012, net-metering provision as approved by the MA DPU limits net-metering to 3% of a utility's historical peak load for private customers and 3% for public entities. The amounts of projects that fall under these caps are as follows:
National Grid’s historical peak load of 40.8 MWs occurred on July 22, 2011 in Nantucket Electric territory; making each 3% limit 1,224 kWs. The private limit also includes those public entities whose generator rating is less than 60kW. Neither limit includes those projects which are considered under the simplified interconnection process.
As of June 6, 2013, in Massachusetts, there are 307 kWs with net-metering service under the private limit and 0 kWs with net-metering service under the public limit.
As of June 6, 2013, there are 783 kWs with applications in the process of being interconnected under the private entity cap and of those 0 kWs have returned the Schedule Z
As of June 6, 2013, there are 0 kWs with applications in the process of being interconnected under the public entity cap and of those 0 kWs have returned the Schedule Z.
Please note: Under current Massachusetts state law, once the limit is reached, net-metering credits will not be available. You will be eligible for net metering credits only if there is still capacity under the limit to accommodate the full rating of your facility at the time you receive your "Authority to Interconnect" letter.
