The transition begins: days 1–30
After your Letter of Intent is accepted by your distribution utility, the formal 90-day transition process begins. In the first month, your Retail Electricity Supplier coordinates with the Retail Metering Service Provider (RMSP) to schedule your interval meter installation. This meter records your electricity demand in 5-minute intervals, a significant upgrade from the simple monthly reading your distribution utility meter provides.
During this period, your RES also finalizes the Retail Supply Contract details, confirms your demand profile based on historical billing data, and begins the registration process with the Independent Electricity Market Operator of the Philippines (IEMOP). Your power supply continues normally throughout.
Metering upgrade: days 15–45
The interval meter installation is the most visible step in the transition. A technician from the RMSP visits your facility to install or upgrade your metering equipment. The installation typically takes a few hours and does not require a power interruption. Your facilities team should be available to provide access to the metering location.
Once installed, the interval meter begins recording your consumption and demand data. This data forms the foundation of your itemized billing and the consumption analytics available through your RES's reporting tools.
Regulatory processing: days 30–75
While metering is being set up, your RES completes the regulatory coordination with your distribution utility and IEMOP. This includes confirming your registration as a contestable customer, establishing the billing and settlement arrangements, and coordinating the supply transition date. This is paperwork-intensive work that your RES handles entirely on your behalf.
Go-live and first billing cycle: days 75–90
On your go-live date, your electricity supply formally transitions from your distribution utility's bundled rate to your RES supply arrangement. The physical delivery of electricity does not change, and the same distribution network delivers your power. What changes is your billing relationship: instead of a single-line bill, you receive itemized reporting showing exactly what you pay for generation, transmission, system losses, and other line items.
Your first RES bill typically arrives within 30 days of go-live. Take the time to review it with your RES account manager, who can walk you through each line item and explain how the charges relate to your consumption patterns.
After day 90: ongoing partnership
Once the transition is complete, the ongoing relationship begins. You have access to consumption dashboards, monthly demand reports, and a dedicated account manager. Your RES monitors your usage patterns and can flag anomalies or opportunities for optimization. This is the visibility and partnership that makes open access valuable beyond just the supply arrangement.
