Whereas there were prices recently of £1,000 per MWh, this week it was £0 or less when demand was balanced by supply. Putin isn't winning this. He's a bad, bad boy. 0 Quote Link to comment Share on other sites More sharing options...

We should be building the capacity for nuclear to provide more. Gas, coal and oil capability should be retained for additional capacity if ever needed, but there is really no reason why the UK cannot source 100% of its electricity from a combination of solar, wind, nuclear and hydro. 0 Quote Link to comment Share on other sites More sharing options...

If you pay by DD and you disagree with any change to the amount you can phone the supplier and discuss the change. If they refuse to reduce it and proceed to take the payment you can tell your bank that you aren't paying it under the DD guarantee and they are required to restore the funds and contact the company. I have done this many times in the past. You just have to know your rights https://www.directdebit.co.uk/direct-debit-explained/direct-debit-guarantee/ If you keep a low balance and your DD fails, you will be charged by the bank and possibly the DD recipient also. Do cash app transfers have the same protections? Zelle, Venmo, etc? 0 Quote Link to comment Share on other sites More sharing options...
cb_diamond Posted October 9, 2022 Share Posted October 9, 2022 Knowing how things were likely to be this winter I didn't do my normal DD reduction from March to October that I have done in previous years, from £130 p/m to around £70 for my combined gas and electricity. As a result and with trying to be more energy efficient as well as having a very energy efficient new build I'm in the odd situation where I've built up an awful lot of credit (plus the govt subsidy) and could easily reduce my payments and get through the winter paying less than last year. 0 Quote Link to comment Share on other sites More sharing options...

We should have been doing that for decades already. The fact that we aren't is the root cause of our problems. The question is whether we have anyone in charge with the ability and desire to solve this issue or not. How big are you planning on these batteries being? Where are we building them? How do you plan on generating enough electricity over and above demand to charge them? And how often will they need replacing? Storing energy generated from wind and solar sounds great, but there is a negative environmental impact from doing so that, at the scale required, negates many of the environmental benefits from using wind etc to generate the electricity in the first place. 0 Quote Link to comment Share on other sites More sharing options...

Unless im missing something why not, under normal circumstances, just set your DD to around £100pm and leave it there? 0 Quote Link to comment Share on other sites More sharing options...

The question isn't what methods there are since Oaksoft is stating that the investment was needed long ago. Alternative methods include Hydrogen, pumped storage or compressed air. 0 Quote Link to comment Share on other sites More sharing options...

Shadow Play Posted October 9, 2022 Share Posted October 9, 2022 (edited) 8 minutes ago, Todd_is_God said: Other than batteries, what methods of storing energy to feed the National Grid are there? I looked into this recently. The following was what I found. I’ve absolutely no idea how costly or efficient any of these would be. Also no idea if they could truly be scaled up to cover the whole of the UK. ETA Could nuclear power not be used for when the sun isn’t shining and / or the wind isn’t blowing? Would that not be cheaper and perhaps even better for the environment than some ideas listed below (assuming something doesn’t go wrong)? Pumped hydroelectric. Electricity is used to pump water up to a reservoir. When water is released from the reservoir, it flows down through a turbine to generate electricity. Compressed air. Electricity is used to compress air at up to 1,000 pounds per square inch and store it, often in underground caverns. When electricity demand is high, the pressurized air is released to generate electricity through an expansion turbine generator. Flywheels. Electricity is used to accelerate a flywheel (a type of rotor) through which the energy is conserved as kinetic rotational energy. When the energy is needed, the spinning force of the flywheel is used to turn a generator. Some flywheels use magnetic bearings, operate in a vacuum to reduce drag, and can attain rotational speeds up to 60,000 revolutions per minute. Batteries. Similar to common rechargeable batteries, very large batteries can store electricity until it is needed. These systems can use lithium ion, lead acid, lithium iron or other battery technologies. Thermal energy storage. Electricity can be used to produce thermal energy, which can be stored until it is needed. For example, electricity can be used to produce chilled water or ice during times of low demand and later used for cooling during periods of peak electricity consumption.

Moomintroll Posted October 9, 2022 Share Posted October 9, 2022 Reliable energy storage is the quantum leap forward we need to be self sustaining, Scotland has abundant Wind,Solar & Tidal energy sources & will be a huge net exporter when capture technology is able to smooth out the ebbs & flows. Sorry @Todd_is_God, just being a grumpy dick. 1 Quote Link to comment Share on other sites More sharing options...

Bairnardo Posted October 9, 2022 Share Posted October 9, 2022 Theres an enormous storage potential in incentivising people to have EVs and keep them plugged in and available to take power. 0 Quote Link to comment Share on other sites More sharing options...
