Beating the heat: How ISO-NE prepares for summer peak demand

As the region gears up for a season of fun in the sun, ISO New England prepares for conditions unique to the hot, humid summer months. Peak demand brought on by warmer weather and an increased reliance on energy-intensive technologies, such as air conditioning, can create complex challenges for the grid operator.

To maintain a reliable supply of electricity to New England’s residents and businesses, the ISO’s System Operations team must rely on carefully planned procedures to increase power generation and curb consumption during periods when demand for electricity threatens to exceed available capacity and reserves. High consumer demand or unplanned resource outages—when a transmission line or generator suddenly goes offline—are typically the reasons for these procedures to be enacted.

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.
