He added that consumers may save even more compared to gas plants. Leviste cited as example the 500-MW supply line in the past three months by First Gas Philippines Corp. to Meralco at an average rate of P5.44 per kWh inclusive of value-added tax. Solar Philippines's offer came after Meralco declared a failure of bidding in a competitive selection process (CSP), in which no company qualified to challenge the proposal of First NatGas in light of the CSP's requirement that "the fuel for the generation of the Price Challenger must be the same as the Original Power Supplier, which is natural gas." Since it was a failed bid, Solar Philippines said Meralco may now choose whether to rebid this under the same terms, or amend the terms to allow other technologies to compete on the basis of cost. A decision could be reached by end of this month.
