More than 45% — about 13,650 MW—of the total generating capacity in New England uses natural gas as its primary fuel. Out of this gas-fired capacity, ISO-NE's Winter Outlook has identified 4,220 MW of natural gas-fired generation at risk of not being able to get fuel when needed due to constraints on interstate natural gas pipelines.
As in 2013 and 2014, in 2015 ISO-NE again proposed a Winter Reliability Program to address concerns over reliability. The 2015-2016 program includes 4 main components: oil, LNG, demand response, and dual-fuel commissioning. According to a December 2015 presentation to the NEPOOL Participants Committee, program participation and expected cost exposure breaks down as follows:
Oil Program
- 81 units submitted intent to provide 4.464 million barrels
- Total eligible oil is anticipated to be 2.965 million barrels
- Total oil program cost exposure is anticipated to be $38.25M (@$12.90/barrel
LNG Program
- 8 units submitted intent to provide at least 1.42 million MMBTU
- Total eligible LNG is 1.278 million MMBTU
- Total LNG program cost exposure is anticipated to be $2.75M (@$2.15/MMBTU
Demand Response Program
- 7 assets submitted an intent to participate; 6 accepted by ISO-NE, to provide at least 26.5 MW of interruption capability
- Total DR program cost exposure is anticipated to be $132K
Dual-fuel Commissioning Program
- 6 units submitted intent to commission Dual Fuel Capability
- 4 units for 2014/15 (1,039 MW)
- 2 units for 2015/16 (735 MW)
- Total additional winter seasonal claimed capability represented: 1,774 MW
ISO-NE will release additional information on actual 2015/2016 Winter Reliability Program operations and costs over the winter period.
