If you live in Ilocos Region (Region I), your electricity bill almost certainly does not come from Meralco. A mix of local electric cooperatives (meralco does not serve this region) handles distribution here, and rates, fixed charges, and even the billing cycle can look different from the Metro Manila numbers most online calculators assume. That gap is exactly why a single national "average bill" estimate is often wrong by hundreds of pesos for households outside NCR.
This page pulls together the specific data for Ilocos Region (Region I) — Ilocos Norte, Ilocos Sur, La Union, and Pangasinan — so you can estimate your bill, find your water district, and check whether rooftop solar pencils out, using numbers built for this region instead of Metro Manila defaults.

Electricity in Ilocos Region (Region I)
A mix of local electric cooperatives (meralco does not serve this region) is the primary distribution arrangement across Ilocos Norte, Ilocos Sur, La Union, and Pangasinan. Ilocos Norte hosts the Bangui Bay wind farm and Burgos wind/solar installations — the region has some of the country's earliest large-scale renewable energy projects.
Because rates outside Meralco's franchise area are set independently by each cooperative or utility and approved by the Energy Regulatory Commission (ERC) on its own schedule, two towns in the same region can post noticeably different per-kWh charges. Use the estimator above as a planning range, then confirm the exact posted rate with your local utility before budgeting.
