Consumers stand to suffer from soaring electricity rates should the Department of Energy’s (DoE) proposed strategy of 100-percent firm contracting for ancillary services (AS) prevail, according to the National Grid Corporation of the Philippines (NGCP).
The DoE has been reiterating the dispatch of ancillary services as a response to thin operating margins and possible load dropping in the Luzon grid at various points this year due to multiple power plants on extended outage.
The NGCP explained that the initial simulations show that power rates can see an upsurge of P0.64 per kilowatt-hour (kWh) for Luzon, P0.54 per kWh for the Visayas, and P1.39 per kWh for Mindanao.
For a household consuming 200 kWh, this means an additional P128 in electric bills of consumers from Luzon, P108 for those in Visayas, and P278 for those in Mindanao.
The NGCP has repeatedly clarified that ancillary services are not meant to replace baseload plants or for any long-term or continuous use. Instead, ancillary services are a stop-gap measure, dispatched only to stabilize and balance the grid in cases of power supply and demand imbalance.
“In times when supply is sufficient, it is meant to run only long enough to bridge the gap between the loss of supply event, and the time that replacement power can be scheduled by the Independent Electricity Market Operator of the Philippines, Inc. (IEMOP), usually within the succeeding hour or two. It should not run for days, weeks, or months on end without violating the EPIRA and prevailing regulatory approvals,” the NGCP said, referring to the “Electric Power Industry Reform Act of 2001”
Under the DoE’s strategy, however, NGCP is being compelled to procure all of its ancillary services requirements under 100-percent firm contract, wherein AS providers will be paid for 24/7 availability, regardless of actual or absent utilization.
NGCP currently contracts both firm and non-firm arrangements for its ancillary services.
The power transmission operator stressed that AS are services, not energy “reserves” that the grid can tap for extended periods of time should major power plants falter. Thus, shifting from the current non-firm arrangements to a firm arrangement will not solve the current lack in supply, as they are taken from the same pool of power plant suppliers, NGCP said.
“Shifting to firm contracting is not the solution to the power supply shortage. We get our power to support AS from the same pool of generators, many of which went on unscheduled shutdowns, and whose current collective output is not enough to meet consumer demand. Signing a firm contract will not make a large capacity power plant magically appear with the stroke of a pen. The only thing that changes is the charging mechanism,” the company explained.
Furthermore, the NGCP noted that many of the power plants asking for firm contracts run on diesel fuel. “Contracting diesel-run power plants for AS, especially if the diesel plants are decrepit and inefficient, will not only be counterproductive, it will drastically hike electricity rates. AS costs are pass-on costs that NGCP does not profit from,” it added.
Even as it is privately owned, NGCP comports its operations in full understanding that its transmission service is a public utility.
It further said that “because of the staggering increase consumers may face in their next power bill if NGCP will be forced to do this, we are hoping that the Energy Regulatory Commission (ERC) should be, at the very least, consulted and given the opportunity to review the policy and study its full impact on the consumers.”
The grid operator rallies on the long-term solution of installing new baseload power plants to meet burgeoning demand.
