AND how we manage our personal energy - for example, adding batteries to arbitrage the cheap daytime energy during the night
- danans 3y agoI do this today with residential batteries on a time-of-use rate plan that is highest between 3PM and midnight (with an average $0.30/kWh price difference between peak and low rates). I end up arbitraging about 5kWh/day (1825kWh/yr ) of usage between those rates, which works out to about ~$500/year in utility bill savings. Compared to the cost of the battery system, that's not much and the payback period is well beyond the life of the battery. In some locations (alas not mine), you can sell your battery's charge back to the grid during, providing grid ancillary services, for an even better ROI. There is still, however, some resistance against opening the gates to leaf-node distributed energy resources from traditional utilities and generators.
