FERC on April 26 approved a settlement requiring the Twin Ridges wind farm in Somerset, Pa., to pay ReliabilityFirst $30,000 over a “litany” of reliability standard deficiencies at the facility.
The commission said in a filing that it would not further review the settlement, filed by NERC in its monthly spreadsheet notice of penalty March 28 along with a separate spreadsheet NOP concerning violations of NERC’s Critical Infrastructure Protection standards (NP24-6).
Exus Management Partners, which claims to manage renewable energy assets worldwide with a total capacity of 11 GW, reportedly acquired the Twin Ridges facility in March from global energy developer Vitol. However, the settlement stems from five self-reports submitted to RF in July and August 2021, the year before Vitol purchased the wind farm from a private equity fund managed by BlackRock.
An operations and maintenance (O&M) company employed by BlackRock informed RF in July 2021 that the plant was in violation of PRC-005-6 (Protection system, automatic reclosing and sudden pressure relaying maintenance). The following month it submitted additional reports of infringements of COM-002-4 (Operating personnel communications protocols) and VAR-002-4.1 (Generator operation for maintaining network voltage schedules).
According to the first self-report, the Twin Ridge owners did not perform required maintenance on several protection system components, including the facility’s only sudden pressure relay, its battery bank and each of its lockout relays. The violation began Jan. 1, 2016, when PRC-005-6 became enforceable, and ended Oct. 20, 2021, when Twin Ridges finished mitigation activities. These included performing the skipped maintenance and implementing annual reviews of its protection system inventory and maintenance activities.
Regarding the COM-002-4 violation, the O&M company reported that “there was no formal program for communications training of the entity’s operating personnel under the previous ownership,” or at least no program for which records could be found. The violation lasted from July 1, 2016 — the effective date of the standard — to Dec. 6, 2020, when the owners finished training operating personnel in the relevant communications process.
The three VAR-002-4.1 infringements similarly involved a lack of records establishing that required maintenance had been performed. Noncompliance began Dec. 22, 2017, the day after RF audited the facility, and ended in January 2022 when the entity adopted new control-room alarm capabilities, a corporationwide VAR-002 procedure and training for operations personnel.
RF attributed all violations to a fumbled ownership transition, suggesting that records were mislaid during interactions between “multiple owners and O&M companies,” along with a lack of oversight by the facility’s former owners and operators in the case of the VAR-002-4.1 violations. It assessed a moderate risk from all the infringements, noting that the small size of the facility limited “its overall … impact and the potential magnitude of harm.”
While the regional entity observed that entities “will not be excused from [their] compliance and reliability responsibilities … merely because [they are] small,” it also remarked on the “proactive actions of new owners and a new O&M,” crediting both BlackRock (which it referred to as the “2018 owner”) and Vitol (the “2022 owner”). RF said it decided to limit the penalty in order to “promote the transparent review and self-reporting seen here.”
