NYS Net Metering


Sustainable CUNY, of the City University of New York, is implementing NYSolar Smart, a project designed to lower the soft costs of installing solar in New York State (NYS) that is supported by the U.S. Department of Energy SunShot Initiative Rooftop Solar Challenge II program and the NY-Sun Initiative. Under the SunShot initiative, Sustainable CUNY formed the NYS Net Metering & Interconnection Working Group that includes all of NY’s major electric utility companies.The working group created the resources below for the general public and solar industry to increase transparency on New York States’s net metering policies.

understanding net metering

Net metering allows consumers with alternative energy systems to export unused energy back to the grid in exchange for credits on their utility bills. These brief videos can help you understand net metering and its effect on your electric bill once you install a solar PV system.

net metering analysis and Capacity Tracking

On October 19th, 2015 the New York Public Service Commission temporarily lifted caps on the amount of net-metered solar energy that can be permitted on a utility system."Rather than engaging in another effort to  arrive at the proper level of the ceiling that would anticipate  perfect coordination with the implementation of REV, the  ceilings shall be allowed to float in the interim until the  calculation and application of “the value of D”  and other  issues affecting valuation of DER is decided.  That is,  utilities shall accept all interconnection applications and  continue to interconnect net metered generation without  measuring the DG capacity against an artificially set ceiling  level.  The interim period will end and the ceilings will close  at the level that accommodates the acquisition of the net  metered generation necessary to smooth the transition to the  implementation of the valuation of DER, including the interim  “value of D.”  At that point in time, any other issues related  to moving from net metering to the valuation of DER will also be  decided." 

The charts below display data from the previous quarter.

Figures 1 & 2: Data reported as of June 30 th , 2015 compares the amount of applications in process and installed to the minimum requirement. “kW Connected” means the amount installed and the application is completed with the utility. “kW Proposed” represents only those applications that have been submitted, but not completed with the utility. You can see from this column below, the majority of the 6% limit has been reached by applications in process.  The “Percent of capacity used” compares the “Total kW” of applications connected and proposed, and compares it to the 6% capacity limit.    



Figure 3: Percent of total net metering capacity limit already installed and in process for non-wind systems as of June 30 th , 2015. National Grid and Orange & Rockland well surpassed the 6% limit this quarter from multiple, large applications with the intention of remote net metering under the former grandfathering law.   


Figure 4: Actual growth trend of projects net metered since May 2013 compared to 6% of 2005 peak demand capacity for non-wind systems. KW includes installed and applications in process.


Figure 5: 392,160 kW is 6% of 2005 peak demand for National Grid. National Grid nearly doubled the cap in just the last quarter.  This is a much faster growth rate than previously seen due to an influx of many 2 MW applications hoping to be grandfathered into previous remote net metering rules where host account’s on small commercial rates (no demand charges) could receive monetary ($) credit values instead of volumetric (kWh) credits to offset satellite account bills. 85% of the applications are proposed, and have not been completed. National Grid is continuing to accept net metering applications per the PSC’s direction.


Figure 6:  Orange & Rockland received 27 applications for 2 MW systems from May 1 through June 1, 2015. The utility notified the PSC on July 13th, 2015 and requested an adoption of a “buy all, sell all” arrangement instead of net metering for those above the current cap. A buy all, sell all tariff would mean the solar customer would have to purchase all energy sent to them from the utility at their applicable service classification rate, and sell excess solar energy to utility at the avoided cost of power which is essentially the supply price per kWh. 75% of Orange & Rockland’s current capacity is comprised of proposed applications that have not been completed yet.
