Market Intelligence

  • The New York ISO (NYISO) released a report on the implementation of carbon pricing in its wholesale electricity market. The proposal to add the social cost of carbon, which would be determined by the state, into power generators’ market price offers would accelerate the state’s transition to 100% zero-emission energy by 2040 that was mandated by the Climate Leadership and Community Protection Act signed by Governor Andrew Cuomo in June 2019.

  • Under the carbon pricing policy, generators would pay for the social costs of the carbon dioxide emitted by their generation. The policy will thus incentivize investment in clean energy with lower carbon emissions, resulting in market efficiency savings of $280-850 million from 2022 to 2040, according to the report. With approval from NYISO stakeholders, the NYISO Board of Directors, and FERC, the carbon pricing mechanism could become effective as early as the second quarter of 2021.

  • Unitil New Hampshire filed proposed default service rates for the December 2019 through May 2020 period. For residential customers under rate class D, the fixed default service rate will be 10.33 cents/kWh, a 34% increase from the current rate of 7.714 cents/kWh. The fixed default service rate for small commercial customers (G2, OL) will increase 31% from the current rate of 6.872 cents/kWh to 8.987 cents/kWh on December 1st.


  • In the 8-14 day window the northwestern section of the country from the Pacific Northwest to the northern Great Plains will see below average temperatures. Average temperatures will prevail in California. Meanwhile, the southern part of the US and the entire East Coast should expect above average temperatures, with the highest anomalies predicted from Texas east to South Carolina.

  • Wetter than normal conditions are expected for the Pacific Northwest and most of the eastern continental US. Moisture from the Gulf of Mexico will bring above average precipitation to the East, with a chance for more precipitation from a tropical system at the back end of the 8-14 day window. The Rockies and the Southwest are expected to be drier than normal for this time of year.
