How does the cost and resiliency compare to purchasing energy from the grid?
For reference, I buy 100% wind source power from Xcell @ $0.14 / kWh. Reliability is generally very good, but to compare apples to apples it would cost ~$500 to purchase a backup generator [1] for the 1-2 hours of outages we have every year.
[1]: a battery system would fulfill a similar role, but I'm not sure of the cost -- and for something that I would essentially never use, it may actually be better for the environment to keep the generator.
- winstonford 11y agoGreat question @oconnore. 2 answers. 1. The target price for Ra http://canopyrising.com/#ra http://canopyrising.com/#ra is $600-800, just under what you would pay for a 1kw emergency generator. Initial market is apartment renters in flat-roof, multi-floor urban buildings, who can not run generators indoors b/c of fumes, etc. 2. Battery capacity built into the Cuba table http://canopyrising.com/#cuba http://canopyrising.com/#cuba allows power arbitrage, buying power at the lowest price during off-peak hours to charge up, then drawing from batteries during peak pricing on the grid. In NYC, Conedison sells power for 7-19 cents during the day, but from midnight until 8a, it costs just over a penny. Voluntary time of use programs are common across the country, but few products exist to leverage them. http://www.coned.com/customercentral/energyresvoluntary.asp http://www.coned.com/customercentral/energyresvoluntary.asp
