Does anyone have any experience with home power storage without solar? I'm not sure solar is worth it at this time, but the idea of stockpiling electric during off-peak hours might be. The utility provider, Coned, has a voluntary time of usage option which allows lower costs during off-peak hours. I'm thinking one could recharge their batteries during this time and be free from usage during peak times.

This calculation I can do. I don't know anything about battery systems though. Thought?

Pros? Cons?

There is a net loss in the charge discharge cycle that will be difficult to overcome without hefty differences in on and off peak rates

Thanks. That's interesting. Is there any calculation or rough estimate on losses?

Prices for electric should be pretty close to the following:

Standard: $0.31/kwh

Using peak/non-peak
Peak: $0.42/kwh
Off-peak: $0.14/kwh

Unless you have a large farming operation, I don't think that you would use enough electricity for it to make a difference. Battery systems are expensive. Plus batteries degrade overtime. I would think that the cost of the batteries would eat up any savings you would have.

I'd like to know too, those rates are crazy high. Ours (below) are much less, and no peak/off peak difference for residential.


$0.085578per kWh for the first 600 kWh


$0.104157per kWh for all over 600 kWh

Wow!! Our rates are .027/kwh. AND I complained when I moved from a county that was charging .023!!

At those rates.....YOUR water heater, stove, furnace, clothes dryer need to run on natural gas or propane. Forget batteries....get rid of everything with a electrical heating element and also shut off phantom loads.

Looks like island electricity. You rarely find electricity that expensive on the mainland.
