New wind power forecast integrated into ISO-NE processes and control room operations 

More precise information about the predicted electricity output from  wind resources improves dispatch efficiency, helps optimize power output from wind generators

Over the past several years, the amount of wind power connected to the New England high-voltage power grid has increased at a fairly quick pace—from approximately two megawatts (MW) in 2005 to more than 700 MW on the system today. Another 2,000 MW of wind generation has been proposed in the region.

ISO-NE now publishing seven-day wind power forecast

Currently, about 700 megawatts (MW) of wind power generation are connected to the New England electric grid. An additional 2,800 MW of wind power are in the ISO’s generation interconnection queue, representing nearly 40% of all generation projects being proposed for development in the region. The ISO is taking steps to prepare for managing the grid with an increasing amount of this resource, which has operating characteristics different from traditional resources in that the fuel—wind—is available intermittently. One major initiative underway this year is the development of a centralized wind power forecast. In May, the ISO began publishing a seven-day wind forecast for New England. Each weekday, a CSV file is made available on the ISO website that provides an aggregate wind power projection for each hour for the next seven days. The forecast is still under development and is posted for informational purposes only; the full, final forecast should be operational before the end of 2013. The forecast is already providing useful data on the expected output of wind power resources in the region.

Regional Greenhouse Gas Initiative surpasses $1 billion in proceeds

On September 5, the Regional Greenhouse Gas Initiative (RGGI) held its 17th auction of carbon dioxide (CO2) allowances. Generators in the nine RGGI states bought a total of 24.5 million allowances in the auction, one for each ton of CO2 emitted in the compliance period. Bids for the CO2 allowances ranged from $1.93 to $6.51 per allowance, with a clearing price of $1.93, the minimum reserve price for the auction. With states generally holding excess allowances, sales of allowances in auction 17 represented only 65 percent of the 37.9 million allowances offered for sale. Proceeds from the auction amounted to $47.4 million, which the states typically spend on energy efficiency, clean and renewable energy, direct bill assistance, and other consumer benefit programs.

ISO-NE creates energy-efficiency forecast methodology, launches EE forecast working group

ISO New England has created a methodology to generate a long-term energy-efficiency (EE) forecast of the region’s state-sponsored EE programs. The goal is to equip transmission planners with longer-term information about the impacts of growing investment in EE.

Data collection for the initial EE forecast is underway. The ISO has developed a tool to gather information on specific EE programs administered by utility program administrators, especially the production cost of these programs (the cost per megawatt-hour savings). On January 9, 2012, the ISO hosted a webinar for utility program administrators to explain the EE data gathering tool.

Hurricane Irene and the New England power grid

Hurricane Irene will go down in the history books in New England. Massive flooding washed out roads and swept away bridges. High winds toppled trees and took down power lines. ISO New England and the Local Control Centers in the region, working with the owners of the region’s power system infrastructure, were in close communication before, during, and after the storm to ensure a coordinated approach to operation of the region’s power system.
