It's more cost effective for the grid to have a localised mesh network of storage it can draw on at peak times. Modern battery domestic storage has the capability to be controlled by your supplier.

Lithium home storage has plummeted in price in the UK

@Discoworx renewables lend themselves to decentralised mesh networks using domestic batteries for grid smoothing takes away a lot of issues with new powerlines and grid scale storage. What you want is a mixed system Currently the fossil companies are fighting tooth and nail to stop it happening, the worldwide fossil subsidies last year was calculated at 7% of global gdp

@Discoworx current nuclear costs x 4 the price of renewable and a lead time to build of 12-15 years In the last 10 years the cost of renewables has dropped by 95%, while I don't expect the same again battery prices should hit the 90% mark Nuclear is cost wise on par with hydro and tidal both have a 100 + year life span and NO decontamination issues or costs

@Discoworx you can run tidal like offshore wind using a slow moving blade like proppelor Their are some trail installations but we haven't invested in it, private companies won't it needs government backing once fully developed it would be an export hit If you install domestic and grid scale batteries you change the demand curve lowering costs by at least 1/2

@Discoworx Hinkley C is now in it's 12th year of building isn't due to be opened for another 3 years and will have a total cost over 35 years including 40 billion in subsidies of 80 billion. The electricity it generates will cost 3.5 times as much as that from the newly opened Dogger bank offshore. To remove peak gas standby plant and replace it with mass storage would cost 30 billion. It would save 30 billion in energy costs in 12 months and every year there after. Octopus offer an overnight rate of 7p per Kwh instead of the daily rate of 20p I have home solar and batteries and any grid electricity I consume even in winter is at the 7p rate. The reason the overnight rate is so cheap is our energy consumption is up to 75% less in the middle of the night as to peak time of 4-7pm with usage being described as a Duck curve. Wind and Nuclear are always ON and it pays to offer people incentives to time shift consumption away from peak periods. The flatter and fatter the duck curve is the cheaper the electricity becomes

Battery prices have been falling rapidly just got some with a new solar install. 3 years ago capital repayment was 15 years now it will be under 6.

Average home uses 8 kwh per day I have 10.4 plus a solar diverter to heat water, the point of the batteries are to open up off peak tariffs and time shift usage.

@drgyt2469 id suggest you spend some money upgrading your insulation. Also In the UK you only need enough storage to cover between 4-7pm As it is my appliances are set to run overnight in the winter using the off peak rate, I also charge up the battery given its winter. People with heat pumps in the UK pre heat and avoid peak time consumption most systems are wet and use a tank The point isn't to be off grid it's to flatten and fatten the demand curve enabling you to get the cheapest rate

@drgyt2469 I've just finished renovation on a 1935 house + extension doubling the ground floor area, it has primary and secondary insulation everywhere I could fit it. The heating came on in October sporadically and will start going off again end of March. The house gets most of its heat from the double glazing which only allows heat in at lower angles as in 1st thing on a morning or during winter sun Secondary insulation isn't expensive it's just a fag to do to an older property, I've primarily used a product called multifoil
