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.*

ISO-NE incorporates wind-powered resources into real-time dispatch with Do Not Exceed Dispatch Project

The change helps improve price formation in the markets and marks an important milestone in ISO New England’s efforts to efficiently integrate renewable resources

On May 25, the region’s wind-powered resources and intermittent hydro resources began taking electronic dispatch instructions from ISO New England for the first time and became eligible to set real-time prices in the wholesale electricity marketplace. These changes were effected by the Do Not Exceed (DNE) Dispatch Project in which the ISO worked with stakeholders to implement a modified electronic dispatch method for these intermittent resources.

FERC approves reliability program for winters 2015/2016, 2016/2017, and 2017/2018

Proposal selected is nearly identical to last year’s program

On July 15, 2015, ISO New England and the New England Power Pool (NEPOOL) filed alternative Winter Reliability Program (WRP) proposals with the Federal Energy Regulatory Commission (FERC) to address the region’s well-documented reliability challenges over the next three winters.

Building on the critical role the first and second Winter Reliability programs’ played in ensuring power system reliability through two difficult winters, the proposals for winters 2015/2016, 2016/2017, and 2017/2018 were designed to carry the region through until 2018, when new market-based performance incentives will go into effect that are expected to address the region’s reliability concerns.

New England governors to explore expansion of Canadian hydro-power imports

On June 17, five New England states announced a collaborative effort to explore expanding the import of large amounts of Canadian hydro power into the region. Connecticut, Massachusetts, Maine, Rhode Island, and Vermont agreed to the regional initiative as a way to help meet carbon emission limits and reduce electricity costs.

According to the press release, “the New England States Committee on Electricity (NESCOE) is charged with evaluating the opportunities, options, and issues relating to the expansion of hydro imports in New England. The states will consider those findings and, as warranted, incorporate them into a strategic plan to be presented to the New England governors for their consideration later this year.”

The study will be tied into NESCOE’s current work on a coordinated regional procurement for renewable energy as directed by a 2012 resolution by the New England governors.
