Queue position Z1-090 in the PJM Interconnection project queue is a Corona Power LLC request to interconnect a 381 MW energy (381 MW capacity) resource consisting of one heat recovery steam unit (the new Unit 8).
A System Impact Study from PJM, dated September 2014, said that Units 1, 2, 3, and 4 will be retired at the Sunbury plant, the site for this new facility. The planned Sunbury Units 5, 6, and 7 are not impacted by this project. Queue Z1-090 is located in Monroe Township, Snyder County, Pa., and is currently scheduled for commercial operation on June 1, 2017.
Notable is that while the PJM study doesn’t say this, the Units 1-4 to be replaced are fired by coal.
Z1-090 will interconnect with the PPL Electric Utilities transmission system at the Sunbury 500-kV substation at the same Point of Interconnection as projects X2-025 and X4-019.
The intent of the System Impact Study is to determine a plan, with approximate cost and construction time estimates, to connect the subject generation interconnection project to the PJM network at a location specified by the project developer.
- Project X2-025 of Corona Power, which is subject to a separate interconnection request, facilitates the interconnection to the PJM system of an increase of 643 MW (Maximum Facility Output) at the Sunbury facility, with a commercial operation target of June 1, 2016. That project involves the gas-fired Unit 5 (227 MW), Unit 6 (208 MW) and Unit 7 (208 MW).
- Corona Power’s X4-019 project also has a commercial target operation date of June 1, 2016, and it covers the same new Units 5, 6 and 7.
