New York state is acting to keep existing nuclear generators operational in an important power play that's interesting for a number of reasons.

NY regulators propose generous Upstate nuclear subsidies | Syracuse.com
SYRACUSE, N.Y. – State utility regulators today released a proposal to subsidize Upstate nuclear plants with annual payments totaling an estimated $482 million a year.
The proposal from the Public Service Commission staff seems likely to please nuclear plant operators, who say their facilities deserve subsidies for providing carbon-free power, and to infuriate anti-nuclear advocates who want more resources devoted to wind and solar.
The public has a brief opportunity to comment -- until July 18 – an indication that the PSC is likely to rule on the proposal at its Aug. 1 meeting.
Exelon Corp., which owns three of the four Upstate nuclear reactors, recently told the commission that the oldest two facilities might close unless subsidies were approved by September.
Exelon had said similar things about a proposal put to the Illinois legislature to incent existing nuclear units there by
guaranteeing a $42/MWh rate for the generators. Illinois' legislature didn't act, and Exelon announced the closure of Illinois units.
The initial Syracuse.com story embedded Public Service Commission staff's recommendation - knows at POLITICO as
Cuomo's nuclear subsidy plan. From the recommendation:
Replacement of the zero-emission attributes with
equivalent amounts of fossil-fueled attributes would result in
an increase of approximately 31 million metric tons of CO2
emitted into the atmosphere over the next two years, according
to a report issued by The Brattle Group.

Staff is proposing
to subsidize zero-emissions attributes from Zero Carbon Electric
Generating Facilities when there is a public necessity to
encourage their preservation. Payments for zero-emissions
attributes would be based upon the U.S. Interagency Working
Group’s (USIWG) projected social cost of carbon (SCC). This
approach is consistent with the Commission’s approach in setting
guidelines for Benefit-Cost Analysis.
This may be the first payment scheme designed to price energy by the social cost of carbon. The formula is:
RGGI is the Regional Greenhouse Gas Initiative - so if it was trading carbon at what the USIWG considers the social cost of carbon the ZEC would be zero. If the combination of the RGGI credit costs, expected market pricing and capacity payments (in the "rest of state", or ROS zone) was equal to, or greater than, the USIWG's social cost of carbon, the price would be zero.
