Walton Electric Membership Corporation Data Access Guide

Walton EMC has deployed AMI smart meters across its territory and exposes hourly interval usage to customers through the myWaltonEMC portal and mobile app. Customers can view and export hourly, daily, and monthly consumption with weather/degree-day overlays. Sub-hourly (15-minute) data and standardized Green Button exports are not available, and there is no third-party interval data access program.

Third-party access to a customer's data requires a manual, written customer authorization submitted to Walton EMC, after which data is typically delivered by export or email.

Walton EMC serves all commercial and industrial members on a single tariff: the Standard Commercial Electric Rate (GS-12). It is a declining-block energy rate tied to billing demand, with the demand-based minimum bill ($50 + $5.25/kW over 5 kW) functioning as an effective demand charge. Billing demand is the highest 15-minute kW over the current month and preceding 11 months, with strong summer ratchet rules (85% of the highest summer peak carries into winter months), so peak management has an outsized, year-long effect. Excess reactive power (kVAR over half the kW) is billed at $0.25/kVAR, making power factor correction relevant for larger loads.
