State of New York’s renewable portfolio standard (RPS)

NEWE YORK, Feb. 9, 2005 — The New York State Energy Research and Development Authority (NYSERDA) has released the final draft of a technical study on integrating wind energy into the New York grid, which concludes that a 10% penetration level of wind can be accommodated without major changes in the planning, operations, or reliability of the state’s bulk power system.

“This technical analysis lays to rest any concerns about integrating substantial amounts of wind energy into the New York grid, and finds that more wind power will in some cases improve reliability,” said American Wind Energy Association (AWEA) Acting Policy Director Michael Jacobs. “The technical findings will also be very useful to other regions that are adding wind to their systems, even with regional differences.”

In particular, the study found that:

* The incremental increase of 10% wind power can be accommodated by existing processes and resource in NY state, whether this is in the minutes, hours, days, or years management time frames;

* Even without forecasts, wind energy displaces conventional generation, reduces system operating costs, and reduces emissions;

* No change to spinning reserve requirements would be needed;

* State-of-the art wind turbines improve post-fault response of the interconnected power grid.

The study focuses on a wind generation scenario of 3,300 MW, corresponding to approximately 10% of New York State’s 2008 projected peak load. The state’s Renewables Portfolio Standard is expected to result in about the estimated 3,700 megawatts (MW) of new renewable generation by 2013. This final draft builds on a preliminary assessment released in early 2004, which also indicated that large-scale wind generation should not cause significant adverse impacts.

AWEA will file technical comments on certain sections of the study.

NYSERDA requested the study from GE Energy Consulting because of this consulting company’s widely recognized expertise on grid integration issues for all technologies. Albany-based AWS Truewind, a significant support contractor, supplied wind resource, wind plant production and forecasting data to GE.

The study is available on NYSERDA’s web site at www.nyserda.org/rps/default.asp.
