Map of Content for the market-trading and contracting layer: the Wholesale Electricity Spot Market, the retail and bilateral arrangements that sit alongside it, and the reserve, dispatch, and certificate mechanisms that settle what gets paid to whom. This page links out to existing concepts/, entities/, and programs/ pages — it moves nothing and duplicates nothing.

Belongs here: a page about how power is bought, sold, dispatched, or settled — market participation, contracting mechanics, or a market body’s role. Regulation of the grid infrastructure itself belongs in Topic: Grid and Transmission ; renewable-specific support mechanisms (feed-in tariff, GEAP, net metering) belong in Topic: Renewable Energy Policy and Support .

Pages

  • Wholesale Electricity Spot Market (WESM) — the central real-time trading platform under EPIRA where generation companies and large consumers exchange power, operated by IEMOP under DOE-approved rules; the page to read on how the spot market itself works.
  • Retail Competition and Open Access (RCOA) — the EPIRA framework letting contestable customers choose their own electricity supplier instead of their franchise distribution utility; the page to read on customer-choice eligibility and supplier switching.
  • Power Supply Agreement (PSA) — the bilateral contract between a generation company and a distribution utility or large customer, the primary way a DU secures power supply outside the spot market; the page to read on contracted, as opposed to spot, power procurement.
  • Competitive Selection Process (CSP) — the mandatory least-cost competitive bidding that distribution utilities and electric cooperatives must run before signing a PSA for their captive market; the page to read on CSP obligations and exemptions.
  • Renewable Energy Market (REM) — the trading venue for Renewable Energy Certificates, where Mandated Participants buy RECs to discharge their Renewable Portfolio Standards obligation; the page to read on how the RPS obligation is actually met, as distinct from the standard itself.
  • Reserve Market and Electricity Derivatives (WESM) — the co-optimized ancillary-service mechanism inside WESM that schedules and prices contingency reserves alongside energy dispatch; the page to read on how the market keeps the grid stable against sudden shortfalls.
  • Ancillary Services (AS) — the services the System Operator must procure to hold grid frequency, voltage, and fault-recovery capability within Grid Code limits. Cross-listed on Topic: Grid and Transmission as a System Operator obligation; here it is a traded, settled market product, and the page to read on how AS is bought and paid for.
  • Preferential Dispatch (RE in WESM) — the two-tier dispatch priority WESM grants to qualified renewable generating units; the page to read on how RE output gets to the front of the dispatch queue.
  • Interim Mindanao Electricity Market (IMEM) — the transitional spot market DOE stood up for the Mindanao grid ahead of its entry into the full WESM; the page to read on Mindanao’s market history before WESM integration.
  • Embedded Generators (EG) — a generating unit connected through a distribution utility’s network rather than directly to the grid, and the licensing, dispatch, and metering rules that follow from that; the page to read on a distribution-connected generator’s market obligations.
  • Lifeline Rate — the subsidized tariff for low-income consumers, delivered as a retail-rate exemption rather than a separate programme; the page to read on how the subsidy is priced into the bill.
  • Independent Electricity Market Operator of the Philippines (IEMOP) — the private non-profit that operates WESM under ERC authorization, having taken over market operations from PEMC; the page to read on who runs the market day to day.
