Rockland Electric Company (RECO)

(b)
In January 2016, the NJBPU approved RECO’s plan to spend $15.7 million in capital over three years to harden its electric system against storms, the costs of which RECO, beginning in 2017, is collecting through a customer surcharge.

In January 2017, RECO filed a request with FERC for an increase to its annual transmission revenue requirement from $11.8 million to $19.7 million. The filing reflects a return on common equity of 10.7 percent and a common equity ratio of 48 percent.

Other Regulatory Matters
At its August 2, 2017 meeting, the New York State Public Service Commission (NYSPSC) voted to issue an order in its proceeding investigating an April 21, 2017 Metropolitan Transportation Authority (MTA) subway power outage. The NYSPSC indicated that the outage resulted from a failure of CECONY’s electricity supply to a subway station and led to a loss of the subway signals. The NYSPSC also indicated that the company’s failure to document the rerouting of secondary services to the MTA facility significantly delayed repair. The company anticipates that, pursuant to the NYSPSC order, it will be required to take certain actions, including performing inspections of electrical equipment that serves the MTA system, analyzing power supply and power quality events affecting the MTA’s signaling services, providing new monitoring and other equipment and filing monthly reports with the NYSPSC on all of the company's activities related to the MTA system. In July 2017, the Chairman of the NYSPSC notified the company that the April 21, 2017 subway power outage incident will likely result in a prudence review of the reasonableness of CECONY’s actions and conduct. The company does not anticipate that the NYSPSC order will commence a prudence review or address cost recovery. The company is unable to estimate the amount or range of its possible costs related to this matter.
