Joyce McLaren of NREL has compiled useful data on utility kW demand charges, previously untracked by the EIA. The raw data can be combed through here but I thought I might quickly summarize the main points of NREL’s white paper and Joyce’s September 19th powerpoint.

  1. $15/kW is about where batteries overtake battery-less solar.
  2. 70% of commercial load is on demand charges

And as one of our recent blog posts documents, in markets with low energy costs and high demand charges, battery-based solar offers quickest economic payback.
