CAISO has narrowed the scope of a generator interconnection plan that seeks to protect smaller transmission owners from disproportionately high costs.

FERC last week approved the PJM cost allocations for its updated Regional Transmission Expansion Plan, dismissing complaints from Dayton Power and Light.

The Organization of MISO States was unable to achieve consensus on how MISO should revise its cost allocation procedures.

The SPP Regional State Committee (RSC) approved a process for reviewing new members’ effect on regional cost allocation, but not before some changes.

FERC rejected the CAISO effort to refund $217 million that the ISO said were overcharged for payments to generators operating under must-offer obligations.

Kansas City Power & Light’s proposal for addressing SPP transmission cost shifts led to a free-wheeling discussion on transmission pricing and the unintended consequences of proposed Tariff changes at the Strategic Planning Committee meeting Thursday.

MISO's mechanism for allocating charges under its settlement with SPP was certified by a FERC administrative law judge the same day the Market Subcommittee met.

FERC ruled against a proposal by MISO and ITC Holdings that would have allocated the costs of phase angle regulating transformers to PJM and NYISO.

FERC said MISO can continue doling out refunds to Wisconsin utilities, upholding the RTO’s new cost allocation methodology for three system support resource power plants in Michigan’s Upper Peninsula.

Stakeholders support the MISO push to revise its cost allocation process for market efficiency projects, but their suggested approaches are a mixed bag.
