13 Days of Low Levels of UK Wind Power Rectified by £632 billion of Powerpack 2 Batteries!






The UK’s installed wind power capacity is 19,261 MW
Load Factor for all wind: 30.1%

At 30.1% load factor, 19,261 MW of capacity is generating on average over the year 5,797.6 MW. 

But for a 13 day x 24 hour period (312 hours) it only generated 963.4 MW. 

That’s 4,834.2 MW lower than average. 

For battery storage to make up this shortfall it would have to deliver 
4,834.2 MW x 312 hours: 1,508,270 MWh

At £419,050/MWh, the cost of battery capacity to deliver 1,508,270 MWh is 
£632 billion
THAT’S 632 BILLIONS OF £££££s

The Tesla Powerpack 2 unit has a capacity of 0.2 MWh, so to deliver 1,508,270 MWh would require: 
7,541,350 Powerpack 2 units.

With a base measurement of 1.308m x 0.822m the land area occupied by 7,541,350 Powerpack 2 units would be 
8.1 km2 (2.85km x 2.85km).

The cost of ‘solving’ a random 13 day intermittency issue is when the idiocy of renewable dissolves into lunacy. Talk of breakthroughs in battery technology and wonderful new storage techniques is revealed as pure dreamland fantasy.

  1. I think it may be useful for some to write out the number in full:
    £632,000,000,000.00

  2. It doesn't add up...29/07/2018, 16:06

    If we look at the performance of the Big South Australian Battery, we find that it has a round trip efficiency of only about 80%. That means you'd need another 25% more energy to charge the batteries up in the first place.

    What I have also noticed is that solar power has also been a little inconsistent. Instead of peaking daily at 8GW it has frequently struggled to get above 6GW on supposedly sunny days during our warm spell.

    1. @It doesn't add up,
      Thanks. I would be grateful for reliable, checkable references for the round trip efficiency of this battery

  3. More facts that will be kept from the people who pay for the travesty of reducing their energy reliability.

  4. You could go a long way by making every house install solar and battery storage

    1. Making ,you mean forcing . And who pays for this forced installation of free power
