A rate structure in which the retail price of electricity increases incrementally as a customer reaches certain thresholds (or ‘tiers’) of total monthly usage. In other words, at ‘Tier 1’ (up to XXX kWh/month), a customer pays $0.0X/kWh; while at ‘Tier 2’ usage (above XXX kWh/month) a customer pays $0.XX/kWh.

Unbundled customers receive their electricity generation and distribution services from separate entities. Customers of MCE are considered unbundled customers because they purchase their electricity generation services from MCE and their electricity distribution services from PG&E.

Bundled customers receive both their electricity generation and distribution services from the same entity. If a customer “opts out” of MCE service, they would be a bundled customer of PG&E.
