Why isn't electricity cheaper?


#864

Yes that quote by the head of the UK National Grid is bizarre.

The vast majority of of electricity customers will continue what they want now: 99.99% reliability, a monthly bill, a stable price.

A lot of what he says is propaganda to appeal to policymakers and regulators. This is inevitable in heavily regulated industries like this.

Everyone want so save the world…but looks like we are going to pay through the nose for it

What is the
proposed
Levy for period 2017 The proposed PSO Levy for the period 1stOctober 2017to 30th
September 2017 is €496.5million.This proposed
figure is approximately €104.1 million (27%)more than the PSO Levy for the previous
period.
A number of drivers are contributing to the increase in the 2017/18 PSO levy, principally increased
renewable generation and the 2015/16 R-factor. Other drivers, including
an increase in the benchmark price, are exerting downward pressure

Sounds like a good idea, but, will it be big enough to carry the load while they spin up a conventional power station to cover shortfalls from the renewables.

just goes to show the advantages of Concentrated Solar Power massive solar plants (with molten salt store etc) over simple PV

e.g.

needs water for cleaning though

For comparison, Turlough Hill can generate 292MW for 6 hours (so it stores a little bit under 1800 MWh).

The Tesla plan is effectively infinitely scalable to need unlike Turlough.

And also has the advantage of being able to function with distributed storage, so rather than having one huge plant with all the power concentrated, you can have power stored in each and every street if you so desire. This would reduce transmission losses.

They can then be charged up by householders as well as commercial renewable sources.

Transmission losses would be reduced but small scale generation is extremely difficult to predict.
This would result in increased reserve requirements which may mean increased costs overall.

It is much more likely to contribute to reduce overall costs on larger scales controlled by the TSO.
Battery storage combined with wind(which has a real negative value when it blows during low demand periods) would appear to be an ideal combination


#873

I was thinking along the lines of having both large scale as well as small scale local storage, even though the power stored in the small scale sites could be very difficult to predict. The larger scale battery sites can use the smaller local sites to pull or push power if required while working with the conventional generators including hydro.

It’s a system, rather than individual components that could make it a very efficient and reliable method of power generation and storage.


#874

That could work.
Given the likely widespread use of electric cars, I can see something similar being implemented with them


#875

Another new electricity supplier, JustEnergy.ie
They will offer a household unlimited electricity for a set price per month, based on current usage, hoping to attract fixed-income customers.
Will offer gas before year end.

Where’s that Bitcoin mining thread gone…

get ready for your (not-so) smart meter

ah shure it’ll cost you €5/year but you’ll be savin’ €20/year

Unsubsidised solar coming in at about 2 cent per Kw/hr

thinkprogress.org/stunner-lowes … 620d04010/

For context the cost of electricity in Ireland is about 14-16 cent per kw/hr

At the 2 cent per Kw/hr the cost of distribution will exceed the cost of generation, making local generation the way to go.

Man dismissed by ESB considered security risk to national infrastructure

Would this role have any responsibility for mitigating risk of copper theft?

What is going on here?
irishtimes.com/business/ene … 0?mode=amp

Eirgrid announces new payment structure for electricity suppliers, and now suppliers are shutting down their power plants
fora.ie/dublin-power-plants-clo … 2-Jan2018/
We can barely supply enough juice to provide a standard of living that we are accustomed to, and now the bonkers decision to have all forms of motor propelled transport powered via electricity and the supply loads needed to charge them. And now electricty suppliers are shutting off the juice.


#881

The least efficient power stations lost out in the auction.
Capacity payments are payments to generators to maintain and upgrade their facilities not to generate electricity
Huntstown and Kilroot are older generating facilities which i assume are less efficient.
Kilroot AFAIK was scheduled to close sometime after 2020 AFAIK


#882

All forms of motor transport is going electric now, really, when was this decision announced

Don’t worry about EVs causing problems for the grid, thats from the Jermy Clarkson school of Science and Engineering


#883

It has not been decided here yet, but major countries have decided to ban petrol/diesel in the next 20 years, including Norway in 7 years time
