This is really hard to estimate and from my personal experience the
amount of members doesn't matter too much. In fact, I'd say: Completely
ignore the amount of members.

A better approach: Start off by measuring your permanent running
infrastructure (Freezers, Fridge, Routers, Switches). Measure the power
consumption of your lights. That will make up the most of your
electricity bill. Even if you have lots of power tools, it's unlikely
that they run even near 24/7.

At RaumZeitLabor, we have an average power consumption of about
700W-1000W, with 300W min (when our space is closed). That's about 4€
per day and 120€ per month. We discussed power saving stuff more than
once, and the sad truth is: It can be done, but at high implementation
costs. I don't know how much your members pay, but in our case, we need
5 non-discounted members to pay the electricity bill with their
membership fees.
