A welcome shift occurred in the nation’s power landscape in January, as wholesale electricity prices experienced a notable decline. The Independent Electricity Market Operator of the Philippines reported a significant easing of costs, offering a glimmer of relief to consumers and businesses alike.
The average rate at the Wholesale Electricity Spot Market (WESM) fell by 18.6% compared to the previous month, landing at P3.56 per kilowatt-hour (kWh). This decrease signals a positive trend, driven by improvements in the overall supply situation.
Despite a slight dip in overall power supply – a 5.3% decrease to 19,152 megawatts (MW) between December 26th and January 25th – demand also softened, falling by 7.1% to 12,492 MW. This balance between supply and demand was a key factor in the price reduction.
Luzon, the country’s most populous island, saw a 9% year-on-year increase in average prices, reaching P3.25 per kWh. This rise was directly linked to unexpected outages at several coal and gas-fired power plants, forcing reliance on more expensive alternatives like oil-based generation.
These forced outages removed a substantial 4,811 MW of capacity from Luzon’s grid, creating a temporary strain. The resulting need to activate higher-cost power sources inevitably impacted prices for the region.
However, the news wasn’t uniform across the archipelago. The Visayas and Mindanao regions experienced substantial price drops, providing significant benefits to local energy participants. These areas saw a marked improvement in market conditions.
Spot prices in the Visayas plummeted by 41.2% month-on-month, settling at P4.24 per kWh. Supply decreased modestly, while demand also saw a reduction, contributing to the favorable price environment.
Mindanao witnessed an even more dramatic decrease, with prices falling by 45.5% to P4.27 per kWh. A notable increase in power supply, coupled with a slight decrease in demand, fueled this substantial price reduction.
The composition of the energy mix remained relatively stable, with coal-fired plants continuing to dominate at 58.7% of the market share. Renewable energy sources accounted for 27%, followed by natural gas at 13% and oil-based generation at a minimal 0.5%.
Looking ahead, experts anticipate further improvements in supply as the dry season approaches. The anticipated commissioning of new renewable energy plants is expected to bolster overall capacity and contribute to price stability.
The extension of a key supply contract for a major gas-fired plant in Batangas also provides a degree of certainty, alleviating concerns about potential power sourcing disruptions. This agreement ensures a reliable energy source for a critical region.
However, officials remain cautious, mindful of the extreme heat experienced in the previous year. The hope is that the upcoming dry season won’t replicate the conditions that led to numerous power alerts and strained the grid.
The WESM serves as a vital marketplace where energy companies can secure additional power when their long-term contracts fall short of meeting customer demand. It plays a crucial role in ensuring a stable and reliable electricity supply for the nation.
