New interconnect deal worked out for 1,024-MW Hummel/Sunbury project in Pa.

PJM Interconnection on July 30 filed with the Federal Energy Regulatory Commission an executed interconnection service agreement (ISA) with Hummel Station LLC and transmission owner PPL Electric Utilities that supersedes a jumble of other agreements for a new gas-fired power plant at the site of recently-retired coal units at the Sunbury power plant in Pennsylvania.

This new ISA replaces an old ISA entered into among PJM, Corona Power LLC and PPL, effective October 2014. “As a result of the current Interconnection Request (adding a new unit, which increases the overall Maximum Facility Output) and an assignment of the project from Corona Power, LLC to Hummel, the Hummel ISA supersedes: (1) the Corona ISA; (2) the conforming ISA among PJM, Sunbury Generation, LP and PPL, effective January 30, 2009, designated as Service Agreement No. 2107 (‘Sunbury ISA’); and (3) with respect to Sunbury Units #3 and #4, the Interconnection Agreement for the Sunbury Generating Station Operating as a Merchant Power Plant between Sunbury Generation, LLC and PP&L, Inc., effective November 1, 1999, designated as FERC Electric Rate Schedule No. 166, filed with the Commission in Docket No. ER99-3446-000,” said the PJM filing. Those oldest agreements basically covered the retired coal plant.

The new ISA covers the Sunbury Generation Facility, to be located at Shamokin Dam, Pennsylvania. The maximum facility output is 227 MW for the new Unit #5, 208 MW for the new Unit #6, 208 MW for the new Unit #7 and 381 MW for the new Unit #8. That is a total of 1,024 MW. “The stated size of the generating unit includes an increase in the Maximum Facility Output of the generating unit of 381 MW over Interconnection Customer’s previous interconnection,” said the ISA. “This increase is a result of the Interconnection Request associated with this Interconnection Service Agreement.” The agreement covers three new gas combustion generators and one heat recovery steam turbine generator.

Under the new ISA, on or before Dec. 1, 2017, Hummel Station LLC must demonstrate commercial operation of all generating units.

A project contact listed in the ISA is: Hummel Station LLC, 5001 Spring Valley Road, Suite 1150, West Dallas, TX 75244, Attn: Joe Jordan, Director Business Development.

Panda Power Funds announced on Feb. 17 that it had entered into a joint venture with long-time project developer Sunbury Generation LP to develop, finance, construct and operate this project, which led to a major revamp of plans, including an uprate of capacity. 

This project is moving forward in other ways:

  • The Federal Energy Regulatory Commission issued a July 15 notice about an application from UGI Sunbury LLC for a certificate authorizing UGI Sunbury to construct, own, and operate new interstate natural gas pipeline facilities (called the Sunbury Pipeline Project) that will supply this power plant. The estimated cost of the pipeline is $178.2 million. UGI Sunbury said it received binding bids for 180,000 Dth/d of firm transportation service from Hummel Station.
  • The Pennsylvania Department of Environmental Protection said in three notices in the May 30 Pennsylvania Bulletin that it has extended, to June 29, 2018, the expiration date for three air qualiity permits for this project.
