Province of Siquijor Electric Cooperative

What Province of Siquijor Electric Cooperative does

Province of Siquijor Electric Cooperative, Inc. (PROSIELCO) is a member-owned electric cooperative incorporated on December 22, 1977, and operating since October 2, 1982, that holds the exclusive franchise to distribute electricity across the entire Province of Siquijor in the Philippines. Headquartered in Larena, Siquijor, the cooperative serves approximately 30,998 active consumers and 33,123 members across six municipalities (Larena, Siquijor, San Juan, Lazi, Maria, and Enrique Villanueva) and 134 barangays, supported by a workforce of 82 employees. PROSIELCO operates a conventional electric power distribution network — including distribution transformers, steel poles, conductors, and kWh meters — with a peak load of 4.559 MW, a base load of 3.119 MW, a 97% system power factor, a 68% load factor, and a 9.3% system loss rate. The cooperative is classified by the National Electrification Administration as a Large electric cooperative with the highest AAA categorization, indicating top-tier operational and financial performance.

PROSIELCO generates revenue through usage-based electricity distribution charges billed monthly to member-consumers, with rates published as unbundled tariffs covering generation, transmission, distribution, and regulatory pass-through components. The cooperative procures wholesale power under a Power Supply Agreement (PSA); the current 15-year agreement with Vivant Energy, signed December 30, 2025, supplies 11 MW of diesel-generated capacity from a plant in Maria municipality, replacing former supplier SIPCOR after the provincial government shut it down in August 2025 for regulatory violations that caused up to 20-hour daily outages. Two pending ERC cases (2026-027 RC and 2026-064 RC) indicate ongoing efforts to diversify supply. Customer segments are horizontally segmented across residential (primary), commercial, and industrial consumers within the franchise area.

The go-to-market is direct-to-consumer within a regulated monopoly franchise: PROSIELCO delivers electricity through its own physical distribution network and communicates with members through its website (prosielco.com), monthly published power rates, procurement notices, and ERC regulatory filings. The cooperative pursues infrastructure expansion through the Barangay Line Enhancement Program (BLEP 2025) and the Total Electrification Program with the Department of Energy (TEP-DOE 2026), and sources materials through its ongoing Regular Procurement Program (RPH). It is not publicly traded, has no parent company, no subsidiaries, and no external private equity or venture capital backing.

Three partnerships are on record, tiered core and minor.

• Vivant Energy (Vivant Corporation subsidiary)coreStrategic or Co-development Partner · 30 December 2025Vivant Energy, a subsidiary of Cebu-based Vivant Corporation owned by the Garcia-Escaño family, signed a 15-year power supply agreement with PROSIELCO to supply electricity to Siquijor province. The agreement delivers 11 megawatts of capacity from Vivant's diesel power plant in Maria municipality to six towns across the province. This partnership was established following the shutdown of the previous provider SIPCOR (owned by the Villar family) in August 2025 due to operational and regulatory violations that caused severe power outages lasting up to 20 hours daily.
• Siquijor Island Power Corporation (SIPCOR)minorOthersPrevious power provider to PROSIELCO. SIPCOR was owned by the Villar family and was shut down by the provincial government in August 2025 for operational and regulatory violations. The shutdown followed severe energy crisis in 2025 with residents experiencing daily power outages lasting up to 20 hours. SIPCOR was the power provider noted in the corporate profile but has been replaced by Vivant Energy.

Direct peers

• Bohol Electric Cooperative (BOHECO I): An electric cooperative serving the province of Bohol, neighboring Siquijor. Closely comparable to PROSIELCO as a member-owned distribution cooperative under NEA oversight, serving a similar Visayas island-province customer base with comparable scale and regulatory framework.
• Bohol Light Company Inc. A privately-held electric distribution utility serving Tagbilaran City and nearby municipalities on Bohol island, neighboring Siquijor. Operates a similar franchise-based island distribution model, making it the closest functional peer to PROSIELCO in terms of scale, customer base, and island-grid operations.
• Visayan Electric Company (VECO): The second-largest private distribution utility in the Philippines, serving the greater Cebu metropolitan area. Comparable to PROSIELCO as a franchised electric distribution utility under ERC regulation, though operating at significantly larger scale (hundreds of MW vs PROSIELCO's ~4.5 MW peak).

Broad incumbents

• Manila Electric Company (MERALCO): The largest electric distribution utility in the Philippines, serving Metro Manila and surrounding provinces with over 7 million customers. A broad incumbent comparable to PROSIELCO on regulatory framework and franchise-based distribution economics, though orders of magnitude larger.
• First Gen Corporation: One of the Philippines' largest independent power producers with renewable and conventional generation assets. Relevant comparable as a Philippine energy-sector counterparty and ERC-regulated entity, though generation-focused rather than distribution-focused.
• Aboitiz Power Corporation: A major Philippine power conglomerate with generation, distribution, and retail supply operations across the Visayas and Mindanao. Comparable to PROSIELCO as a major player in the Philippine electricity value chain with interests in distribution and generation across the Visayas region.

Others

• Vivant Energy Corporation: The Garcia-Escaño family-owned power generation company and PROSIELCO's new 15-year PSA partner supplying 11 MW from a diesel plant in Maria, Siquijor. Comparable as a counterparty and adjacent ecosystem player in the Philippine distribution supply chain rather than a competitor.
• National Grid Corporation of the Philippines (NGCP): The private concessionaire operating the Philippines' transmission grid. Comparable as a regulated electricity infrastructure operator under ERC oversight and a necessary counterpart for any distribution utility including PROSIELCO.
