How much is the typical utility bill for a warehouse in California?

Does anyone know what is a typical utility cost for a warehouse in Northern California (Bay Area)?
We are looking to get a 20,000 sqft warehouse that will operate for 12-15 hours a day.
Main utility usage includes lighting and heating. It will also include a kitchenette with refrigerator and some appliances. There is no heavy machinery or massive electrical appliances/equipments.

Thanks.

5-700$ depends on if all lighting is usd and what kind
