V. SCWC's Proposed Rate Design

SCWC states that it is not proposing to make any changes to the existing structure of any BVES rates, and is only proposing a rate increase to recover the revenue requirement for the generating facility.

SCWC has five customer classes or tariffs within the residential group and three tariff schedules within the commercial group. The residential tariffs include full-time customers residing in Bear Valley, low-income customers, multi-family customers that are sub-metered and multi-family customers that are not sub-metered, and residential customers that are part-time and seasonal. Residential customers who are part-time or seasonal, and constitute approximately 65% of all residential customers, do not receive a baseline allowance.⁹ Full-time residential customers pay a monthly service charge, and an increasing energy block rate. The energy block rate has three tiers, with the first energy block equal to the baseline allowance. Part-time or seasonal customers pay a monthly service charge, and a single energy charge that applies to all customer usage. These customers are subject to a minimum monthly bill of $23 per month regardless of usage.¹⁰

SCWC has three tariffs for its BVES commercial customers (A-1, A-2, and A-3). Commercial customers qualify for a specific tariff based on maximum monthly kWh customer consumption. Each tariff has two tier energy rates, such that the second tier rate is greater than the first tier rate.

The interruptible tariff for the four Large Power customers includes a monthly fixed charge comprised of a meter charge and an availability charge, time of use demand charges, and time of use energy charges.

The street lighting class is the final customer group. Monthly charges are calculated on a per lamp basis and vary by type of lamp. Energy charges are based on a single rate.
