NYS Net Metering
December 12, 2014
Public Service Commission Proposes Five Milestone Steps, Including Changes to Net Metering Caps.
Governor Cuomo Press Release
Sustainable CUNY, of the City University of New York, is executing a U.S. Department of Energy SunShot Initiative Rooftop Solar Challenge II program, NYSolar Smart, a project to implement solutions to lower the soft costs of installing solar in New York State (NYS). Under this initiative, Sustainable CUNY formed a NYS Net Metering & Interconnection Working Group that includes all of NY’s major electric utility companies.

Net metering allows consumers with alternative energy systems to export unused energy back to the grid in exchange for credits on their utility bills.

net metering analysis and Capacity Tracking
One goal of the working group is to increase transparency for stakeholders as utility territories approach the net metering limits established by the Public Service Commission (PSC). NEM Analysis Dec 2014 <pdf>
Figures 1 & 2: Current NYS law requires utilities listed below to provide net metering to customers for a minimum of 6% of their 2005 peak demand for non-wind systems and 0.3% for small wind systems. Once total kW net metered reaches the capacity, utilities are not required to offer additional net metering to customers. Data reported as of September 30, 2014 compares the amount of applications in process and installed to the minimum requirement.
*PSEG-LI’s “kW Proposed” data for applications in process is estimated based on last quarter reports. PSEG-LI is not regulated by the PSC, and can choose to update their net metering capacity as they see fit. It currently remains at 3% of 2005 peak demand.
Net Metering 'Limits'
In New York State, the PSC establishes a level of distributed generation for which each regulated, investor-owned utility is required to offer net metering in its service territory. These limits are generally set as a percentage of each utility’s peak electric load from a particular year, and they represent the amount of installed capacity for which the investor-owned utilities are required to provide net metering to their customers. They are referred to as minimum ‘limits’ or ‘caps’, because it is the minimum generation capacity a utility is required to purchase net metering from its customers.
history and current policy
Initially, for solar PV and other non-wind technologies, these limits were set at 1% of each utility territory’s 2005 peak demand. However, Central Hudson Gas & Electric reached the limit in July 2012, and following a petition by Hudson Valley Clean Energy, the PSC issued an order directing them to triple the capacity limit to 3% in October 2012. On July 1, 2013 the remaining regulated NYS utilities were directed to raise the net metering limit to 3% of 2005 peak demand.
Most recently, on December 15, 2014 the PSC directed the NYS utilities to raise the net metering limit to 6% of 2005 peak demand. Public Service Law (PSL) §66-j sets the limits for non-wind systems (solar electric, biogas, micro-hydro, micro-combined heat and power, fuel cell technologies) and §66-l for wind systems. Wind net metering capacity is currently 0.3% of 2005 peak demand. The PSC may increase the limits if it is determined to be in the public’s interest. Publicly owned state and municipal utilities are not obligated to offer net metering, but some, like PSEG Long Island, provide similar programs. PSEG Long Island’s current net metering limit is 3% of 2005 peak demand for solar PV and other technologies and 0.3% for wind.
It is important to note, the law does not prohibit the utilities from providing net metering beyond the required limit to additional customers. In the past, National Grid continued to offer net metering once the 3% capacity was reached in order to not disrupt the market, and Central Hudson has filed petitions to the PSC to raise the limit when they were close to reaching it.
The following charts detail the amount of generation capacity that is net metered (measured in kilowatts or kW) for each utility as of September 30th, 2014, and compares it to the amount of net metering the utilities are required to provide. As soon as the limitation is reached for a given utility, it will no longer be required to accept net metering applications unless the 6% of 2005 peak demand limit is raised.
