# How much does it cost to run 24kWh on my diesel generator?

I've got a generator, and I'm wondering since my monthly usage is 719kWh how much would it cost to run the house per day if fuel is \$4/gallon?

• A lot depends on generator efficiency. Model and idea of peak vs average load might help. Jun 15, 2018 at 22:11
• it is not possible for us to answer your question .... think about what you are asking .... the answer is easy, but you are the only one that can answer it Jun 16, 2018 at 0:08
• Your monthly electrical usage figure isn't enough for people to answer, you also need the monthly run hours. If the generator runs 24/7, you're using power at a rate of 1 KW according to your question. If you're using power at the rated capacity of 5 KW and running it 20% of the time, you would have the same monthly usage. At 1 KW, you won't use only 20% of the fuel, you'll use substantially more, so the fuel per KWh will be much higher. Jasper's answer is enough to tell you that at half-capacity, fuel costs will be high, but if accuracy is needed, you'll need to add load/run-time figures. Jun 16, 2018 at 3:16
