Consumer Advocates Push for More Power Generation in Mindanao to Combat Rising Electricity Costs

Amid rising electricity rates across parts of the Davao Region, a consumer advocacy group is pushing the Department of Energy (DOE) and the Mindanao Development Authority (MinDA) to expand efforts attracting power generation investments to Mindanao. The group argues that a larger, more diversified power supply base is essential to insulating consumers from price volatility in the Wholesale Electricity Spot Market (WESM).

The call comes as multiple electric utilities and distribution companies in the region have announced rate increases in recent months, primarily driven by higher generation costs and elevated pricing in WESM, where electricity trades in real time to meet immediate supply needs.

In a statement released July 6, the Davao Consumer Movement highlighted that recent electricity adjustments expose a critical vulnerability in Mindanao's power sector. As available supply tightens, many power distributors face greater exposure to spot market fluctuations, leading to elevated generation charges passed directly to consumers.

"The latest adjustments in electricity rates highlight a broader challenge facing the region's power sector. As supply tightens, many power distributors have become more exposed to fluctuations in prices at the Wholesale Electricity Spot Market (WESM), resulting in higher generation charges that are ultimately passed on to consumers," the organization stated.

Utilities with heavier reliance on WESM face heightened vulnerability to sudden price spikes, particularly during periods of constrained capacity, peak demand, or unexpected power plant outages.

Distribution company data from May and June 2026 illustrates varying degrees of WESM dependence across the Davao Region. Northern Davao Electric Cooperative (Nordeco) sourced 73.63 percent of electricity from the spot market. Davao Light and Power Co. drew approximately 40 percent of supply from WESM. Davao Oriental Electric Cooperative (Doreco) relied on the market for 12.87 percent of its requirements, while Davao del Sur Electric Cooperative (Dasureco) obtained just 0.53 percent from WESM during the comparable period.

These figures underscore how a utility's power supply composition directly shapes the generation charges appearing on consumer bills. Generation costs represent the largest element of residential electricity expenses and reflect the actual expense of purchasing electricity from suppliers. When utilities source substantial power from WESM, they become more susceptible to market price movements, especially when reserve capacity runs thin.

Industry specialists have long recognized WESM's essential function in maintaining electricity availability, allowing utilities to acquire supplemental power during demand surges. However, spot market participation is intended to function alongside—not replace—long-term supply contracts, which typically offer more predictable pricing and stability.

The Davao Consumer Movement stressed that maintaining equilibrium between contracted capacity and selective WESM participation can help shield consumers from sudden price jumps while preserving adequate supply during peak periods.

"The data also underscores the value of maintaining a balanced power supply portfolio. Long-term bilateral power supply agreements, complemented by prudent participation in WESM, can help cushion consumers from sudden spikes in spot market prices while ensuring sufficient electricity supply," the advocacy group emphasized.

The organization also appealed to the DOE and MinDA to sustain promotion of an investment environment supporting development of new power facilities—encompassing both traditional and renewable generation—to fulfill Mindanao's rising electricity demand.

The DOE has consistently projected strong electricity consumption growth across Mindanao as regional economies expand, industrial operations scale, and urban areas develop. National authorities have equally prioritized renewable energy, energy storage systems, and generating capacity expansion to enhance grid reliability and maintain adequate operational reserves.

MinDA has consistently designated energy reliability as fundamental to Mindanao's economic trajectory, underscoring that accessible and reasonably priced electricity proves critical to drawing business investment and supporting regional industries.

The Davao Consumer Movement concluded that expanding generation infrastructure and broadening power source diversity would reduce long-term reliance on WESM, contributing to more stable electricity pricing for both households and enterprises.

"Mindanao's growing economy requires a power sector that is both reliable and affordable. Encouraging new investments in power generation today is a long-term consumer protection measure that can help provide more stable electricity prices for households and businesses in the years ahead," the group concluded.
