Rates lowest in more than five years or since January 2010
MANILA, PHILIPPINES, 7TH September 2015 - Meralco announced that after four consecutive months of reduction, the overall rates for its residential customers this September will go down by PhP0.57 per kilowatthour (kWh). This brings the total reduction to PhP2.13 per kWh over the past five months. This month's reduction also marks the seventh time this year that rates have gone down.
For a typical household consuming 200 kWh, the overall electricity bill will go down by PhP114 compared to last month. At PhP8.55 per kWh, this month's overall rate is lower by PhP1.81 compared to September 2014's PhP10.36 per kWh. Meralco said this is the lowest in more than five years or since January 2010.

Lower generation costs from PSAs and IPPs due to higher dispatch

The reduction in the overall rates was primarily due to the generation charge, which decreased by PhP0.42 per kWh from last month. At PhP4.13 per kWh, this September's generation charge is also the lowest since January 2010.

Several large generating units, namely, South Premiere Power (Ilijan), Sem-Calaca Power, Quezon Power, and Therma Luzon (Pagbilao) improved their dispatch levels in August after experiencing plant outages during the July 2015 supply month. In particular, Ilijan increased dispatch level from only 48% in the July supply month to 81% in August. Ilijan 1 was on a scheduled maintenance in July (affecting 27 days) while Ilijan 2 was derated during the Malampaya gas restriction last July 13-16. Meanwhile, lower fuel costs from Malampaya brought down prices from the First Gen plants (Sta. Rita and San Lorenzo).

Apart from the lower generation costs, adjustments from prior months (e.g., cover cost deductions from Malampaya, following the supply restrictions from previous months) helped further bring down the generation charge for September.

Charges from the WESM, on the other hand, registered a negligible increase of PhP0.006 per kWh.

The share of PSAs, IPPs, and WESM to Meralco's total power requirements, meanwhile, were at 47, 46, and 7 percent, from the previous month's levels of 43, 46, and 11 percent, respectively.

Adjustments in other bill components

In addition to the generation charge, transmission charge also registered a reduction of PhP0.04 per kWh due to lower Power Delivery Service and ancillary service charges. Taxes and other charges likewise went down by PhP0.05 per kWh and PhP0.06 per kWh, respectively.

Meralco's distribution, supply, and metering charges remain unchanged after it registered a reduction last July.

Meralco reiterated that it does not earn from the pass-through charges, such as the generation and transmission charges. Payment for the generation charge goes to the power suppliers, while payment for the transmission charge goes to the National Grid Corporation of the Philippines (NGCP).
