Description (excerpt):

We use simulated load and PV generation profiles, based on 17 years of weather data for 15 cities, various building characteristics, 9 PV system sizes, and 4 panel orientations

• Demand charge savings are calculated for demand charge designs with and without seasonally varying prices and ratchets, and for various peak period definitions and averaging intervals

• This study focuses on demand charge savings from solar, alone, without storage or load management; upcoming work will examine demand charge savings from solar plus storage

• This study focuses on residential customers; upcoming work will focus on commercial customers

• This study focuses on implications of demand charges for solar customers; upcoming work will consider how customer bill savings align with utility cost savings from distributed solar
