Connecticut PURA, in draft decision, grants approval for CL&P to build switching station project

The Connecticut Public Utilities Regulatory Authority (PURA) on Sept. 27 said that it grants approval for Connecticut Light and Power (CL&P) d/b/a Eversource Energy (NYSE:ES) to build the Towantic Switching Station and 1575, 1585 and 1990 Lines Modification Project.

“The authority also grants approval to conduct commissioning tests and energize the facilities as necessary during construction, and following completion of the project,” the PURA said in its “consent calendar proposed final decision,” or draft decision.

As noted on the PURA’s website, the draft decision is to be addressed at the PURA’s Oct. 5 regular meeting.

As the PURA noted, Eversource in late August filed an application requesting that the PURA grant approval of the project, which includes construction of a switching station adjacent to the Towantic generating station and modifying transmission facilities from the Bunker Hill substation to Structure 1446 near the Oxford substation by way of the new Towantic switching station.

As TransmissionHub reported, the project includes:

  • Building a new 115-kV switching station adjacent to the Towantic generating station
  • Modifying 115-kV electric transmission facilities from the Bunker Hill substation, located at Clough Road in Waterbury, south to the Towantic switching station
  • Modifying 115-kV electric transmission facilities from the new switching station south to Structure 1446 near the Oxford substation located at Commerce Drive in Oxford

The project, which covers 7.1 miles in length, is being undertaken by the company to satisfy its obligation to facilitate the installation of the necessary transmission system and transmission system upgrades and equipment for power generator entities that request to interconnect to the CL&P transmission system, the PURA said.

The project, which includes construction in the towns of Waterbury, Middlebury and Oxford, does not involve any new or additional crossings of any other utility facilities, the PURA said.

Construction of the project is scheduled to begin this month and conclude in October 2017, the PURA said.

Among other things, the PURA said that the company is to advise the PURA of the date on which construction is completed.
