Residential Demand Charges in Colorado
In 2016, Public Service Company of Colorado (PSCo) filed a request for rate design modifications, including a tiered monthly “Grid Use Charge” for all residential customers and a voluntary residential demand – time-of-use rate. The Company’s stated intent for the proposed Grid Use Charge was to act as an interim step before the implementation of a demand charge. On behalf of Energy Outreach Colorado, Synapse conducted an analysis of PSCo’s proposal and Tim Woolf provided expert testimony before the Colorado Public Utilities Commission. Synapse’s testimony challenged the Company’s proposal to move residential customers toward demand charges because such charges are inconsistent with fundamental rate design principles, create inefficient price signals, are complex and difficult for residential customers to respond to, place undue burden on low-usage and low-income customers, and may ultimately increase long-term electricity costs.
