DOE backs ERC plan for regional WESM secondary price caps in Visayas and Mindanao
Published · Updated
What happened
The Department of Energy publicly backed the Energy Regulatory Commission's plan to apply regional secondary price caps in the Wholesale Electricity Spot Market for the Visayas and Mindanao after recent grid stress episodes. DOE said ERC modeling indicated the Visayas average August spot price would have been PHP 8.47/kWh instead of PHP 18.59/kWh if the cap had been in place.
Why it matters
This is a same-cycle policy intervention in the spot power market after recent red alerts in the Visayas. It can change generator bidding behavior, spot-price formation, and retail pass-through expectations in two major grids as regulators weigh consumer relief against investment and reliability signals.
The Department of Energy said on September 16 it supports an Energy Regulatory Commission proposal to impose regional secondary price caps in the Wholesale Electricity Spot Market for the Visayas and Mindanao. The DOE cited ERC simulations showing the Visayas average price for August could have been reduced to PHP 8.47/kWh from PHP 18.59/kWh under the proposed mechanism. The move follows repeated grid stress and red alerts in the Visayas, and puts immediate focus on how fast regulators can translate the proposal into an enforceable market intervention without weakening supply incentives.
