MANILA, Jan. 12 (PNA) — The Department of Energy (DOE) has ordered the Philippine Electricity Market Corporation (PEMC) to make a billing simulation when the trading at the Wholesale Electricity Spot Market (WESM) for the reserve capacity affects schedule and pricing of energy capacities.
In a DOE circular released Monday, it said PEMC is required to make a billing simulation calculation after the billing cycle, which will be circulated to the WESM members, involved in the central scheduling and dispatch of energy and contracted reserves.
Reserves serve as the ready power when some plants go on unplanned outage.
PEMC was also ordered to issue an error notice and conduct market re-runs during the affected trading period.
Power suppliers are also required to submit reserve capacities offer equal to one half-of their day ahead transmission schedule to account for the dispatchable plants.
During irregularities, WESM Market reserve rules will prevail as based on WESM Dispatch Protocol Manual.
The circular said power generators are only allowed to offer reserve capacity, if they have an Ancillary Services Procurement Agreement (ASPA).
These are support services necessary to sustain the transmission capacity and energy that are essential in maintaining the power quality, reliability & security of the Grid. Its primary function is to maintain the load generation balance of the system.
Similarly, the ancillary services offers will also be accepted based on WESM’s dispatch protocol manual.
Generation companies, whom supply power capacities, are also required to run during their allotted time, still based on WESM protocols.
“All trading participants and other WESM members shall comply with the timetable and procedures for scheduling and dispatch that are set out in this protocol and WESM dispatch protocol manual as such procedures apply to them,” it said.
Thus, this ensures that there will be less disorganization in the passing of power supply.
Also, the gen companies are required to offer their full reserve maximum capacity and submit a reserve offer to WESM.
PEMC is the operator of the WESM, while WESM is the market for trading power capacities. (PNA)
