cost of electricity

shx88

Could someone help with this please?


If the price per electrical unit is 13.05c. Find the cost of operating 12.5KW motor continuosly for a period of 8.5 hours.

Thanks

First, divide watts by 1000 to get kilowatts:
watts / 1000 = kW
Then multiply kilowatts by the hours of usage to get kilowatt-hours
kW * hours = kWh
Finally, multiply kilowatt-hours by the cost per:
kWh * (cost per kWh) = cost to operate

Around €13.87

No need to divide in this case, a unit is a kWh (kilowatt-hour) and the machine is rated in kW.
So, a 12.5kW machine running for 8.5 hours will consume 12.5*8.5 = 106.25 kWh.
At €0.1305 per kWh, that's 106.25*0.1305 = €13.87 as pointed out above.
To get the full cost (if the above unit price doesn't include VAT), you'd have to add 13.5% VAT to the above, for a total of €13.87*1.135 = €15.74.

Oh Jaysus I forgot about the taxman!! Don't leave him out op. He is sensitive like that!!

Thanks for the help people

bumping this because:
I notice that the pso levy is increasing to €5.36 per month from 01/10/14.
checked back previous bills and noticed that it also increased in the december bill last year. The difference in this October and last October is 131%. yep, unbelievable one hundred and thirtyone per cent increase in the PSO levy in a year. Who authorises this, presumably the energy regulator and for what purpose? So we can keep bogs open and burn uneconomical peat in generating stations? water tax, property tax and bog tax. What's next?

Just heard it on the Joe Duffy show, glad that somebody else noticed it. Stealth tax, subsidising turf (dirty* and uneconomical) burning electricity generating stations. Something that you would expect in the old eastern block countries.

* if turf is not dirty why is there a carbon tax on peak briquettes?

A 137% increase is really only 37%. The cost of electricity has decreased but the transmission costs have increased as Has the cost of prividing redundancy to the grid so that's where the pso costs has increased th AUP ( average unit price) has decreased

:rolleyes:hi Ted1,

no not talking about the cost of electricity, each company has a slightly different rate. Not talking about transmission, again each company has a different rate (I am with SSE and I think they have the most expensive transmision rate (standing charge)) I am talking about the public service obligation which is the same for all companies as it's government imposed on the companies

from SSE website

Changes to PSO Levy from 1 October 2014

From 1 October 2014 the Public Service Obligation (PSO) Levy is increasing to €5.36 per month (excluding VAT). The PSO Levy applies to all electricity customers under legislation and is charged to all electricity customers regardless of meter type and energy supplier. It is designed to support the national policy objectives of security of energy supply, the use of indigenous fuels such as peat, and the use of renewable energy sources in electricity generation.

it it waddles like a duck, quacks like a duck and looks like a duck - chances are it's a duck. If it looks like tax...............it's tax. And they even charge vat on it: rolleyes:

Your missing the point,
With electricity you pay for the generation and transmission.
Traditionally the generation cists were what it cost to generate the electricity. But with the addition of renewable you now have to pay for reserve capacity,so your paying for fossil plants to sit idle, so that if there's no wind they can kick in. If there was no PSO you would pay more for electricity. So your bills are the same and if not are less than they would be without a pso

confess I am a beaten docket on this.

So having a thought about this: The more wind farms we have - the more fossil plants we have to have lying idle - in case the wind drops and we are dependent on wind energy- the greater the cost of PSO in future years. Could it actually reach the stage where the PSO would be equal to actual usage at some future stage?

Maybe the Brits are right.

I just got a nice letter from Electric Irl saying they were delighted to reduce my ESB by 3%, good customer, loyal, yada, yada, fcuking yada.
What they didn't tell me is that the business PSO crap thingy is going from €1.54 per KVA to €2.85 per KVA.
A rough calculation for me means that my PSO levy is now approx 40% of my electricity usage without the standing charge or vat.
Here's another one. If I fcuked off on holidays for 12 months and didn't as much as turn on a light switch, my 'ESB bill' would be €1766.57 inc vat.
I don't care what this money is going towards, it's a rip off.

Now, I feel a little better :rolleyes:

Edit: I just noticed they didn't charge me for Oct's PSO so my bill looks a little lower than usual. But on the 1st of Jan I'll get hit with 3 months PSO at the new price.

emeldc, sound like you are a beaten docked on this reasoning too.

listened to a discussion on Sean O'Rourke this morning. The greens want lots and lots more wind farms, the other panelist (McCarthy?) said it was nonsense and we should close down all peat burning stations now and keep new and efficient gas burning stations on (we apparently close the more efficient gas stations during times of excess generation) in order to keep these relics of a bygone age open. We also import 'dirty' electricity from Uk. Don't understand this either, maybe it's something to do with not taking nuclear produced electricity.

Upshot of all this is: our carbon footprint since windfarms etc came on the scene is that we are now producing more carbon from electricity generation than the peak of electricity generation in 2007/8.
