Database of State Incentives for Renewables and Efficiency (DSIRE) - Established in 1995, DSIRE is currently operated and funded by the N.C. Solar Center at N.C. State University, with support from the Interstate Renewable Energy Council, Inc. DSIRE is funded in part by the U.S. Department of Energy.

Net Metering - By National Grid
Intermittent generators, such as solar- and wind-based generators, only produce electricity when their energy source is available (e.g. when the sun shines or the wind blows). Conversely, when their energy source is not available, intermittent generators do not produce power (and may even consume small amounts of electricity for their power electronics).
With distributed generation (DG), intermittent generators are often connected behind the same utility meter as customer loads (e.g. HVAC, consumer electronics, lights) that can be turned off and on based on the needs of the customer. As a result, on-site electric power production does not necessarily match on-site electric power consumption (also known as the customer 'load' or 'demand') on a moment-to-moment basis.
Therefore, sometimes DG customers are importing power from the grid (consuming more power than they are generating on-site), and other times DG customers are exporting power to the grid (generating more power than they are consuming on-site). In Massachusetts, net metering allows these DG customers to financially balance out the total amount of energy imported with the total amount of energy exported over the course of a billing period (typically about a month). Then, the customer is only billed (or credited) for the net difference between these two amounts.
