Interconnection Standards
Interconnection Standard: Docket No. 2009-219 - Order Adopting Interconnection Rule

 

Summary:  In January 2010, Maine's Public Utility Commission (PUC) adopted interconnection procedures. These rules apply to all transmission and distribution utilities operating in Maine. The interconnection procedures set four tiers of review for interconnection requests for all eligible technologies and systems subject to Maine PUC jurisdiction. The four tiers are not subject to jurisdiction of the Federal Energy Regulatory Commission (FERC).

Standby Rates
Policy: Central Maine Power Company Rate SB

 

Summary: Central Maine Power Company, the largest investor-owned utility in Maine, provides standby service to CHP systems under its Rate SB. This rate has a minimum flat standby charge of $2,000, and then charges actual usage under the customer’s regular rate using the peak monthly demand to charge for usage on standby days. This is seen as neutral toward CHP deployment.

Output-Based Emissions Regulations
Policy: Code of Maine Rules, Department of Environmental Protection Chapter 148

 

Summary: Applicable to generators larger than 50kW, Maine’s output-based regulations promulgate standards for NOx, SO2, particulate matter and CO emissions. CHP systems receive credit for heat recovery, and that thermal credit can be taken as long as the system is at least 55% efficient.

CHP in Renewable Portfolio/Energy Efficiency Standards
Policy: Renewable Resources Portfolio Requirement

 

Summary: Adopted in 1999, Maine’s Renewable Resources Portfolio Requirement allows CHP to count towards renewable resources in the state, provided it is at least 60% efficient. Maine electricity providers must supply at least 30% of their total sales as renewable resources. In 2007, Maine created mandatory standards for new generation resources, with a goal of 10% of new energy resources to be supplied by renewable resources by 2017.

Net Metering

Description: All of Maine's electric utilities -- investor-owned utilities (IOUs), consumer-owned utilities (COUs, which include municipal utilities and electric cooperatives) -- must offer net energy billing (net metering) for individual customers. IOUs are required to offer net metering to eligible facilities with capacity limits up to 660 kilowatts (kW). COUs are required to offer net metering to customer-generators up to 100 kW, but, they are authorized to offer net metering to eligible facilities with capacity limits up to 660 kW at their discretion.

Net metering is available to owners of eligible, qualified facilities, including facilities generating electricity using eligible combined heat and power (CHP) systems. CHP systems must meet efficiency requirements in order to qualify for net metering: micro-CHP 30 kW and below must achieve combined electrical and thermal efficiency of 80% or greater, and micro-CHP 31 kW to 660 kW must achieve combined efficiency of 65% or greater.
