average kWh usage per year??

[KustomKreation]

So i have just rented my newest (and hopefully final for a long time) workshop space, and for the first time having to set up my own electricity contract with a provider. In the past i haven't had to do this as the electricity usage was included in the rent.

I have most of the main machines (table saw , jointer, thicknesser,mitre saw etc etc.) and the average power of each is around 2kW.

My shop is quite a busy one and is used on a day to day bases by at least two of us.

What would you say the average kWh per year would be for a busy shop running the machines day to day plus the addition of lights etc??

Pull the usage from your last shop. They shouldn't have a problem providing that. I do fairly often.

it's not possible to do it from my last place due to the type of place it was. i found that the average for a household is about 3000kWh per month, so i would say my shop might run at about 4000kWh per month, due to the higher power consumption of the machines. which gives me 48,000kWh per year , then if i add an over head and round it up to about 60,000kWh per year. Does this seem like a reasonable figure?

i found that the average for a household is about 3000kWh per month.

Do those people live in malls?

My state's average is 731 kWh/mo, my own home uses ~ 650.

WTF ? Are they running 500 Watt bulbs in all 179 rooms?

For August, my kWh hours was 989 for a cost of $137.32. This includes the main house, the guest house and the shop. A/C for the houses and a lot of work in the shop. A large number of machines are 220 volt. I have a lot of power hungery monsters. My highest in 19 yrs has never been higher than 1200 kWh.

Where did you get your numbers from? Southern or western states?

You can make an estimate by taking the power consumed by the tool in kW (1HP is approximately equal to 0.75kW for tools labeled in HP) and multiplying it by the number of hours per month you expect it to run. Make these estimates for all your tools and add them up. Make sure to consider your heating and cooling systems if those are electric, your light fixtures, and add a little for overhead.

Example: 2 HP dust collector running four 40 hour weeks.

2HP * 0.75 * 40 * 4 = 240 kwH of energy consumed by the dust collector over four 40 hour work weeks.

Example: Twenty 32W fluorescent light fixtures running 10 hours per day every day.

20 * 0.032 * 10 * 30 = 192 kWh energy consumed per month

BTW, residential usage estimates vary a lot based on what area of the world you are from and what type of fuel is used for central heating and water heating. Most of our energy at home is used heating and cooling, so depending on whether your water heater, stove and HVAC uses electricity or gas greatly changes the typical monthly electricity use.

If you guys check my link, you'd see that all US regions are represented.

2kW/mo for residential service is way above average, everywhere in the US.

I've never heard of an electricity contract... Shouldn't you just pay for what you use?

In areas where you can choose an electric provider, some providers offer discounts with a contract.

The alternate providers did not work for me. After lots of promises, lies, and contract mumbo-jumbo in mice type, I ended up back with "The Electric Company"...
