I’ve updated my calculation of the Long Range Avoidable Cost (LRAC) for the Visayas that is based on the mechanisms specified in the ERC’s final Decision on Kepco-Salcon contract with CENECO.
The ERC based their permitted pricing to Kepco on a January 2008 Base Date for estimates and permitted certain items to be indexed from that date. The Base Tariff was P4.2511/kWh (based on January 2008).
One of the allowed pass-throughs is the movement in coal prices from that date. Interestingly, coal skyrocked from that date and even more interestingly have settled back to a price (January 2009) that is actually slightly below the January 2008 benchmark. So if the Kepco plant went on-line today, would they be permitted to charge a rate that is approximately P4.2511?
Nope. They would be able to charge a prices that is about 32% higher than that – about P5.61/kWh.
I’ve updated my LRAC model to track prices on a monthly basis, based on actual historical indices, and it can be found (and downloaded) online here.
There are three reasons why the price has gone up over the past 12 months.
#1 – There is an O&M component that is permitted to increase at inflation – a mix of U.S. and Philippine inflation indices.
#2 – Even though coal pricing in January 2008 is about the same as January 2009, there is a currency exchange adjustment permitted and the movement of the Philippine peso vs. the U.S. dollar allowed a 15% increase in both the fuel price and in the capital cost recovery price (that otherwise would be flat except for the currency adjustment).
#3 – Kepco-Salcon can pass on a 12% VAT.
So my model is showing that with all the adjustments, if the Kepco plant went commercial today, the ERC mechanism would permit them to charge a rate that is approximately P5.61/kWh, or about 32% higher than the base price of P4.2511 allowed in the decision.
So when someone tells you the Kepco price is P4.25/kWh, don’t buy it. Or rather, if you can buy power at that price, you better.
