Long-term forecasts: Electricity usage will remain flat and peak demand is expected to grow slowly

ISO-NE has published its annual CELT, energy efficiency, and PV forecasts

ISO New England has published its 2016-2025 Forecast Report of Capacity, Energy, Loads, and Transmission (CELT), a primary source for assumptions used in ISO system planning and reliability studies. It provides a 10-year snapshot of the New England power system, including the total generating capacity of resources in the region, the breakdown of the region’s generators by fuel type, a link to the list of transmission projects proposed, planned, and under construction to ensure system reliability, and the long-term forecast for growth in energy use and peak demand. ISO New England’s long-term forecast for electricity use is developed each year using state and regional economic forecasts, 40 years of weather history in New England, and other factors. The CELT also includes results from the ISO’s latest energy-efficiency (EE) forecast and solar photovoltaic (PV) forecast, which project the load-reducing effects of EE resources and “behind-the-meter” PV resources connected at customer sites to local distribution systems.

2016 summer outlook: sufficient electricity supplies expected

Some natural gas generators may need to get their fuel from other sources during pipeline construction

Under normal weather conditions of 90 degrees Fahrenheit (F), electricity resources should be sufficient to meet consumer demand this summer, with a forecasted peak of 26,704 MW megawatts (MW). Extreme weather of 94°F could push up electricity demand to 29,042 MW. Construction work on the region’s natural gas pipeline infrastructure will require some power plants to obtain fuel from different sources. View the press release.

ISO-NE marks Earth Day 2016 with an update on energy-efficiency, solar, and wind resources in New England

How the region is on its way to meeting states’ “green power” goals

New Englanders take note: as the world marks the 46th annual Earth Day on Friday, April 22, widespread efforts are well underway here, in our six-state region, to develop cleaner sources of electric energy and reduce electricity use. ISO New England has been working closely with both the states and industry stakeholders to help quantify and integrate regional developments related to energy-efficiency (EE) programs and wind and solar resources, two renewable sources of power.

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.
