Announcements

NYISO Compliance Filing–FERC Order 719
On May 15, 2009, the NYISO submitted its filing in compliance with the Federal Energy Regulatory Commission’s (FERC) Final Rule on Wholesale Competition in Regions With Organized Electric Markets (Order 719). The FERC order applies to all of the nation’s Independent System Operators and Regional Transmission Organizations. Order 719 requires enhancements to the NYISO’s arrangements for monitoring the competitiveness of the markets it administers (Market Monitoring), and requires the NYISO to confirm that it satisfied heightened FERC requirements in other areas including responsiveness to stakeholders and customers, the integration of demand response resources into the markets, the accuracy of economic signals sent by the markets at times when the supply of electricity is barely sufficient to meet demand (scarcity pricing), and facilitating long term contracting by willing participants in electricity markets.
New York State Energy Plan -

May 15, 2009 - NYISO Comments on the Interim Report of the Energy Coordinating Working Group Regarding the 2009 New York State Energy Plan
On May 15, 2009, the NYISO submitted comments on the 2009 New York State Energy Plan Interim Report presented by the Energy Coordinating Working Group on March 31, 2009. The NYISO comments supported the Interim Report’s preliminary findings regarding the importance of adding renewable resources and demand response resources to build the State’s clean energy sector; the need for additional natural gas infrastructure; preparing for the advent of plug-in hybrid electric vehicles; modernizing and expanding New York’s aging electric system infrastructure; integrating cleaner, more efficient resources that will help the State meet its environmental goals; promoting intrastate and interregional collaboration; and maintaining sufficient liquid fuel storage capability. The NYISO urged that the draft State Energy Plan reflect and build upon the successes of New York’s competitive, wholesale electricity markets.
November 26, 2008 - NYISO Comments for New York State Energy Plan

NYISO Symposium & Conferences

Foundation to the Future: Infrastructure, Innovation, Investment - April 30, 2009 - Albany, NY

In opening remarks to the April 30 symposium, NYISO President & CEO Stephen G. Whitley said, "A decade of experience has shown that wholesale electricity markets are serving the economic, environmental and energy needs of the Empire State."

Since the inception of wholesale electricity markets in New York State:

Wholesale electricity prices - adjusted for fuel costs - have declined
New generation and interstate transmission have been added.
Power plant efficiency and availability have improved.
Reliability has been strengthened
Renewable green power resources are increasing
Demand-side innovations have been fostered

Presentations, reports, and studies provided by panelists are available to download from the website Speaker/Panelist page.
