Regional air emissions 2017: long-term reduction trends continue 

Since 2001, SO2 down 98%, NOx down 74%, CO2 down 34%

Note: This article was updated following the publication of the final 2017 ISO New England Electric Generator Air Emissions Report.

Regional emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) declined in 2017 compared to the previous year, according to data compiled for the 2017 ISO New England Electric Generator Air Emissions Report. The lower emissions were due largely to a decline in electricity generation by power plants that use fossil fuels. The year-over-year declines continued long-term reductions in the emissions produced by New England power plants.

Spotlight video: An integrated approach to wind power

Over the past decade, wind power has grown significantly in New England, accounting for more than 3,300 gigawatt hours of production in the region’s wholesale markets in 2018. ISO New England has produced a trio of videos detailing the steps taken behind the scenes over the years to integrate wind resources into the region’s power system. The ISO has worked diligently to weave wind energy into our operations, markets, and system planning procedures. These efforts have laid a solid foundation as developers look to add more wind power, especially offshore, to the system in the coming decade.

ISO-NE analyzes potential impact of offshore wind during historic cold spell

Acting on a request from the Massachusetts Clean Energy Center (MassCEC), ISO New England recently released a high-level assessment of the potential impact of offshore wind on the region’s power system during the historic cold snap from December 24, 2017 to January 8, 2018.

Earth Day 2018: Setting regional solar and wind power records in New England

This Earth Day (Sunday, April 22)—or any day—you can learn about the role that renewables and other clean-energy resources are playing in the region by visiting ISO New England’s Key Grid and Market Stats and Grid in Transition webpages. Following are some snapshots of where the region stands, with links to learn more.

ISO-NE, NEPOOL, and PTO AC make joint filing regarding the interconnection clustering methodology 

Update 11/1/2017: FERC has issued its order accepting the interconnection queue clustering revisions. FERC rejected all protests and determined that the clustering revisions increase efficiencies, better inform the decisions of project developers, and allow project developers to share the costs of the upgrades necessary to accommodate their interconnection. By allowing interconnection requests to be studied in a cluster, the clustering revisions should provide a means to relieve the queue backlog in northern and western Maine, which is one of the primary obstacles to interconnections in that region.

Significant price variation on May 18 highlights operational challenges of operating the grid during spring and fall

Real-time prices ranged from a high of $758.88 MWh in the northeastern Massachusetts and Boston pricing zone to a low of -$71.07 MWh price for power from New Brunswick

Thursday, May 18, 2017, was a hot one. If you have an interest in energy, you may have checked the New England locational marginal pricing (LMP) map that day, expecting to see prices rise across the region, responding to the hotter than normal weather. Instead, you saw an unusual, rainbow-like effect on the map, indicating a wide variation in real-time wholesale electricity prices. The real-time price spread was caused by challenging power grid circumstances that can occur mainly during spring and fall (but also any time of year, depending on resource availability): when unseasonable weather drives a spike in demand while major energy infrastructure is offline for maintenance.
