CO SB009

Adds new statute 40-2-130 establishing a consumer right to install, interconnect, and use energy storage systems on residential property without unnecessary restrictions or discriminatory rates.

Defines "energy storage system" as any commercially available customer-sited system including batteries and batteries paired with on-site generation capable of storing and delivering energy through chemical, thermal, mechanical, or other means.

Requires the Colorado Public Utilities Commission to adopt rules allowing energy storage system installation and use by utility customers, with approval processes that are simple, streamlined, and affordable.

Prohibits utilities from requiring additional customer-sited meters beyond a single net energy meter for monitoring energy storage systems, except the Commission may authorize metering requirements for certain large systems.

Applies to qualifying retail utilities but excludes municipally owned utilities and cooperative electric associations; takes effect August 8, 2018, unless subject to a successful referendum petition requiring voter approval in November 2018.
