NYISO white paper on potential benefits of energy storage in NY electricity markets

The New York Independent System Operator (NYISO) has released a 16-page white paper highlighting the possibilities “Energy Storage in the New York Electricity Markets”. The document discusses potential benefits of energy storage, including those relating to intermittent sources of power generation, such as wind:

Wind power, in terms of both capacity and generation, has surged in New York State in recent years. Since the beginning of 2007, more than 1,200 megawatts of wind capacity has been added to the grid. The continued growth of wind as a generation resource is expected for the foreseeable future due to a variety of factors including open access to the grid, price signals provided by NYISO’s wholesale electricity markets, the State’s Renewable Portfolio Standard (RPS), New York’s participation in the Regional Greenhouse Gas Initiative (RGGI), and the potential for Federal programs controlling carbon emissions.

The NYISO Interconnection Queue includes almost 7,000 megawatts of wind power projects, which represent about 40% of the generating capacity in the queue. While there are no guarantees that all of the proposed projects will be built, the significant number of potential projects is an indicator of the positive prospects for further wind development in New York State.

Energy storage resources, combined with the NYISO’s pioneering wind dispatch system, can help New York take full advantage of its wind power resources….

NYISO releases wind energy-related white papers

The New York Independent System Operator (NYISO), which manages the state’s electricity grid, recently released three white papers that relate to the integration of wind generation facilities into New York’s grid.

We understand that NYISO welcomes comments on them. Comments to NYISO should be directed to Kathleen Carrigan, Acting VP of External Affairs, NYISO, kcarrigan [at] nyiso.com.

The white papers discuss System Dispatch, Fuel Diversity,  and Transmission Expansion. Per NYISO, the reports are:

Integration of Wind into System Dispatch
Incorporating significant wind powered generation is a key to achieving the goals of New York State’s renewable portfolio standard (RPS). The NYISO has introduced system and operating changes to better utilize New York State’s existing wind resources, and pave the way for their continued growth. Those efforts and proposals for further enhancements are detailed in the NYISO white paper.

The purpose of this paper is to review work done to date, identify the current challenges of integrating large amounts of wind generation into the New York transmission system, and propose changes to the market rules that will improve the reliable dispatch of wind resources in New York State.

Transmission Expansion in New York State
Since 2000, more than 6,500 MW of new generation has been developed, predominantly in the regions of New York State with the greatest demand for power, and nearly 1,000 MW of transmission has been added to bring more power into those regions. However, there has not been a major high-voltage transmission addition inside the state for over 20 years. The NYISO white paper, prepared with assistance from Energy Security Analysis, Inc. (ESAI), reviews transmission planning processes and investment activity in New York State and neighboring regions.

The NYISO worked with ESAI to draft this Transmission Expansion White Paper in order to review the potential and actual drivers of transmission expansion activities in New York State and its neighboring control areas. While PJM and ISO-NE have facilitated a great deal of investment in transmission expansion projects to address reliability, it appears that the NYISO will be able to best promote transmission expansion through the development of its economic planning process and the Congestion Assessment and Resource Integration Studies which will begin after the 2009 CRP is issued.

Fuel Diversity in the New York Electricity Market
Fuel diversity is a crucial component of the reliable and efficient operation of wholesale electricity systems. This NYISO white paper, developed with assistance from the Analysis Group, explores the significance of fuel diversity and its impact on the New York electricity market.

This paper identifies trends that have led to the electric industry’s focus on fuel diversity. It examines various meanings of fuel diversity within an electricity market; discusses various economic, reliability and environmental dimensions of fuel diversity; explores the impacts of various events on fuel or technology-dependent energy systems; looks at approaches used in other regions to address fuel diversity; and identifies options to address fuel diversity that are both well aligned and poorly aligned with New York’s electricity markets.

Transmission report from WIRES

Transmission and storage. Storage and transmission. Perhaps the major challenges standing in the way of making full use of the on-land wind resources in New York and beyond.

Enter a new transmission report.

Earlier this month an industry group fashioning itself WIRES (Working Group for Investment in Reliable and Economic Electric Systems) released a report that intends to be “a thorough exposition of the methods currently employed by various states, industry, and investors to integrate [] locationally-constrained resources [such as wind]  into the electric grid.”

It indicates a number of “most effective” practices. These are:

  • Regional transmission planning is crucial. That is, the grid upgrades should not just be state or local issues. 
  • The variability of wind and other resources can be diversified through regional operations and planning. Together with better forecasting, WIRES believes such practices can greatly enhance the ability, and reduce costs, of bringing more wind onto the grid. (The report cites a New York study on point.)
  • Appropriate cost allocation and cost recovery will contribute significatnly to promoting investment in needed transmission.
  • And The queue proceses now employed by RTOs [such as NYISO] constitute a critical “gating” issue that must be addressed before issues associatied with transmission access or dispatch can rise to an equivalent level of importance. (Note: NYISO is currently examining its queue procedures.)

The report concludes:

This Report [] highlights a major new challenge: how to efficiently interconnect and integrate into the grid the location-constrained and often-variable clean energy resources that have become the focus of so much domestic energy policy. This is particularly important at a time when the Nation is poised to increase its use of renewable and other location-constrained forms of electric generation and to target significant reductions in greenhouse gas emissions. WIRES believes this Report will be a significant contribution to meeting the need for clean energy through infrastructure enhancement.

New York State wind power expands

Schenectady Daily Gazette (9/28) reports on expansion of wind industry in New York:

Wind power will soon become a bigger part of the state’s energy picture. In September, there were over 700 megawatts of wind generating capacity in commercial operation in New York. By next summer, wind capacity is expected to grow to more than 1,200 megawatts, while proposed projects would add another 6,500 megawatts of wind capacity by 2011. The New York Independent System Operator is already preparing for the increase in wind power.

NYISO ready for more wind generation on electricity grid

The New York Independent System Operator (NYISO) announced today that it

has introduced system and operating changes to better utilize New York State’s existing wind resources, and pave the way for continued growth of economical, emission-free, renewable power resources in the Empire State.

(NYISO had announced its plan to do just that last April.)

NYISO contracted with a leading provider of wind resource information (AWS Truewind) to obtain wind power forecasts for each wind power project in the state, based on meteorological data and historical operating characteristics of each. Those data are then fed directly into the NYISO operational systems that determine the balance of load and generation.

NYISO indicates that it is one of the first ISO/RTOs in the country to implement such a system, which is considered a “best practice” in the industry worldwide.

NYISO further reports that as of September 1, 2008, there were over 700 megawatts (MWs) of wind generating capacity in commercial operation in New York state, and that wind capacity in New York is projected to grow to more than 1,200 MW by the summer of 2009.

New York wind energy developments

Offshore wind gaining traction

Wall Street Journal (9/3) reports on the increasing interest in offshore facilities, particularly off the east coast of the United States, where a relatively shallow outer continental helps to contain the potential cost (and viewshed challenges) of siting offshore wind facilities:

…And New York City officials are talking with wind-power developers about erecting turbines on a massive tract of the Atlantic Ocean about 25 miles from Manhattan. Offshore wind power seems likely to be the largest source of renewable energy for the city, says James Gallagher, senior vice president for energy policy for the New York Economic Development Corp. The idea is part of a broader plan by New York Mayor Michael Bloomberg to curb the growth in the city’s demand for fossil-fueled energy.

US National Renewable Energy Laboratory calculates economic, environmental savings

This item is from earlier in the summer, but of note. A “down and dirty” study by the National Renewable Energy Laboratory (of the US Department of Energy) finds that the:

economic benefits from 1000 MW [megawatts] of development in New York to be $1.3 billion, annual CO2 reductions are estimated at 2.5  million tons, and annual water savings are 1,230  million gallons.

New York recently had some 8500 MW of nameplate wind generation in the NYISO queue.
