The Connecticut Public Utilities Regulatory Authority (PURA), in an Oct. 5 final decision, granted approval to Connecticut Light and Power (CL&P) d/b/a Eversource Energy (NYSE:ES) to conduct commissioning tests and energize the facilities related the Towantic switching station, as necessary during construction, and following completion of the project.
As noted in the decision, Eversource in August filed with the PURA an application seeking approval of the Towantic Switching Station and 1575, 1585 and 1990 Lines Modification Project, which covers 7.1 miles in length, and includes building the switching station adjacent to the Towantic generating station, as well as modifying transmission facilities from the Bunker Hill substation to Structure 1446 near the Oxford substation by way of the new switching station.
The project 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 interconnection is in accordance with the large generator interconnection procedure that is included in Schedule 22 of the ISO New England (ISO-NE) tariff, 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.
Project construction is scheduled to conclude in October 2017, the PURA said.
The PURA said that it “finds that the company has satisfied all of the application requirements and grants approval of construction at the location cited.”
Eversource is to advise the PURA of the date on which construction is completed, the PURA said, adding that it will not require a field inspection.
