MANILA ELECTRIC CO. (Meralco) will refund residential customers at a rate of P0.59 per kilowatt-hour (kWh) in their August electricity bills following approval by the Energy Regulatory Commission (ERC). The refund is part of a P9.5-billion amount approved by the regulator after Meralco over-recovered distribution charges due to delays in the rate-setting process. ENERGY SALES RECOVERYMeralco expects electricity sales within its distribution network to grow this year after recording a recovery in July. Energy sales volume increased by 6.9% in July, with Meralco expecting the growth to be sustained. Meralco is also seeking to capture part of the rooftop solar market through its subsidiary MSpectrum, Inc., which provides solar systems to residential and commercial customers.
