Negros Power December 2025 Electricity Rates Explained
The drop in Negros Power December 2025 electricity rates results from adjustments in both power supply and transmission charges. While some cost components increased slightly, others declined significantly. When combined, these movements led to a net decrease in electricity rates for December.
This balance shows how changes in demand and system conditions directly affect monthly power pricing.
Power Supply Cost Adjustments
One major factor behind the rate reduction is the update in the Wholesale Electricity Spot Market (WESM) rate. The WESM rate dropped from ₱7.6709 per kWh to ₱6.0475 per kWh, a decrease of ₱1.6304 per kWh.
Lower electricity demand following recent typhoons across the Visayas contributed to this reduction. As demand eased, overall generation charges declined by ₱0.4339 per kWh, helping pull down the total electricity rate for consumers.
Transmission Charge Adjustments
At the same time, transmission-related charges experienced a slight increase. Ancillary Service Charges rose from ₱60.2813 per kW to ₱62.9213 per kW. This adjustment reflects system conditions after the Visayas typhoons and the need to maintain grid stability.
For residential consumers, this change is equivalent to an increase of around ₱0.1932 per kWh. Despite this increase, the impact was smaller than the savings generated from lower power supply costs.
