ISO-NE launches 2017 Regional Electricity Outlook 

Annual report describes transformation of New England’s power system

ISO New England has published its 2017 Regional Electricity Outlook, an annual report looking at the challenges and trends impacting New England’s power system, as well as the innovative solutions the ISO and regional stakeholders are pursuing to ensure reliable electricity for the region’s homes and businesses—today and into the future. The report and companion webpages look back on the changes in New England’s electricity industry over the past two decades, while exploring the changes currently underway in the region.

A full version of the 2017 Regional Electricity Outlook is available for download.

How a Patriots Super Bowl affects the region’s power grid

The New England Patriots are back in the Super Bowl, set to take on the Atlanta Falcons Sunday night in Texas. Millions of football fans across the region will be watching, and so will ISO New England system operators—not to cheer on the home-town favorite, but to ensure the region’s power grid reliability. Even when the game is thousands of miles away, the Super Bowl can have a big impact on regional electricity demand—before, during, and after the game. Like players celebrating in the end zone after a touchdown, demand spikes and dips throughout the game. Grid operators must closely monitor the fluctuations and be ready to respond quickly. Electricity supply must be kept in precise balance with consumer demand at all times—and failure to do so could result in grid instability.

2016/2017 winter outlook: sufficient electricity supplies expected

Natural gas pipeline constraints remain a concern, Winter Reliability Program implemented

Electricity supplies should be sufficient to meet New England’s consumer demand for electricity this winter, but possible natural gas pipeline constraints could limit electricity production from natural gas power plants. A Winter Reliability Program has been implemented to incentivize gas and oil-fired power plants to procure sufficient fuel before winter begins. View the press release.

As ovens heat up on Thanksgiving Day, so does electricity demand

For many around New England, the ritual is the same: Wake up early on Thanksgiving morning and start prepping dinner, firing up ovens for turkeys, stuffing and pies. The holiday brings a lot more activity than a typical fall Thursday morning and also changes the way ISO New England plans for the region’s energy use that day.

On most fall days, electric demand peaks in the early evening, as people around the region return home and begin household chores like laundry and cooking dinner. But on Thanksgiving, ISO New England’s system operators have seen consumer demand for electricity peak much earlier – often around noon – making it the only day of the year where electricity demand peaks this early.

Summer 2016 recap: Uneventful, until August

Summer 2016 was fairly uneventful until August arrived with its long stretches of hot, humid weather that pushed up demand for air conditioning and the electricity that powers it. Despite a high number of unexpected resource outages on one August day, ISO New England’s control room operators were able to operate the power system reliably that day and throughout the summer.

New energy-storage options emerging in New England; ISO-NE publishes primer and makes FERC filing on market participation

June 22 update: Information added on ISO-NE’s May FERC filing. Proposed project megawatts (MW) were also updated to reflect the withdrawal of 50 MW of battery storage to have been included as part of a proposed new natural-gas-fired generator.

For the first time, grid-scale (or utility-scale) battery storage projects are seeking to join New England’s regional power system. Late last year, three projects with a combined 94 megawatts (MW) in nameplate capacity applied for interconnection in Maine, with one planning to go live by the end of 2016 and the other two in 2019.*
