FERC on Thursday ordered Federal Power Act Section 206 proceedings for five SPP transmission owners seeking to develop projects under the RTO’s Order 1000 competitive solicitation process.

The commission accepted revised formula rate templates and protocols for ATX Southwest (ER15-1809-001, EL18-12); Transource Kansas (ER15-958-003, EL18-13, ER15-958-004); Midwest Power Transmission Arkansas (ER15-2236-001, EL18-14); and Kanstar Transmission (ER15-2237-001, EL18-15, ER15-2237-003). But the commission ordered 206 proceedings because the companies’ filings did not provide for inclusion in their annual updates sufficient descriptions and justifications for the allocation of costs between them and their affiliates.

FERC also set a 206 proceeding for South Central MCN, saying its revised protocols “attempt to define the scope of future filings” under FPA Section 205 (ER15-2594-003, ER17-953, EL18-16). The commission said South Central had provided an adequate description of its cost allocation methodology as required by an order in October 2015.
