  Changes in the profile of prices in wholesale electricity markets prompt
utilities to redesign their tariffs and adjust their time-of-use periods to
ensure a more adequate cost recovery. However, changing the rate structures
could adversely affect commercial consumers by increasing their electricity
bills and hindering their ability to reduce costs using techniques like net
energy metering. As time-of-use periods are adjusted, consumers will need to
rely on the flexibility of distributed energy resources to achieve cost
reductions. This paper explores the effect that Pacific Gas and Electric
Company's redesigned rates have on the electricity bills of consumers with
different demand profiles. Sensitivity analyses are conducted to examine the
effect of asset sizing on reducing costs under each tariff.
