FERC on Monday ordered settlement judge procedures for a dispute involving an American Electric Power subsidiary’s transmission rates (EL17-85).

In August, East Texas Electric Cooperative (ETEC) and Northeast Texas Electric Cooperative (NTEC) filed a joint complaint asking the commission to reduce Southwestern Electric Power Co.’s (SWEPCO) current base return on equity from 11.1% to 8.41% — a 269-basis-point reduction. In granting the co-ops’ request for a hearing on the issue, the commission set a refund effective date of Aug. 31, 2017.

ETEC and NTEC buy power from SWEPCO under a revised supply agreement among the three parties, while NTEC and SWEPCO also have a separate agreement. The 11.1% base ROE in the contracts originated in a formula rate settlement filed by SWEPCO in 2001 for the NTEC contract, and the utility carried over that rate when it filed the ETEC-NTEC agreement in 2009.

The co-ops now contend that capital costs for electric utilities have declined significantly since the ROE was set in the initial agreement. As a result, their ratepayers are overcompensating SWEPCO by $2.43 million annually.

ETEC and NTEC filed testimony from independent consultant J. Bertram Solomon, who argued the 11.1% ROE rested on the commission’s previous one-stage discounted cash flow (DCF) methodology and outdated assumptions about utility debt costs. Updated financial data and the two-step DCF method adopted by FERC in 2015 produced a zone of reasonableness of 6.42 to 10.62% and a median of 8.41%, Solomon’s analysis showed.

SWEPCO asked the commission to dismiss the co-ops’ complaint, saying the 8.41% ROE falls 216 and 191 basis points below the ROEs the commission approved in previous cases involving ISO-NE and MISO, respectively. The utility requested FERC delay any proposed refund effective date by five months, if it set the complaint for hearing.

The commission said it found the co-ops’ DCF analysis to be “adequate” in establishing a sufficient case that SWEPCO’s cost of equity “may have declined significantly below the level of its existing 11.1% base ROE.” FERC said it was unpersuaded by SWEPCO’s arguments against the zone of reasonableness, and it rejected the utility’s request to delay refunds.

“We find no merit in [SWEPCO’s] assertions that the commission should delay any appropriate relief to [its] customers,” FERC said, “and we expressly decline to do.”

The commission said that barring a settlement agreement, it expects to issue a decision by Sept. 30, 2019.

ETEC separately filed complaints against SWEPCO and three other AEP subsidiaries in June, arguing the companies’ base ROE in SPP’s AEP West pricing zone should be reduced from 10.7% to 8.36%. FERC earlier this month established hearing and settlement judge procedures in that case (EL17-76). (See AEP Base ROE Complaints Ordered to Settlement.)
