Grid-scale battery costs: $/kW or $/kWh?
…to rapidly add MW, then the grid is going to fall over. This is why we care predominantly about batteries producing MW. https://thundersaidenergy.com/2022/09/01/solar-volatility-tell-me-lies-tell-me-sweet-little-lies/ https://thundersaidenergy.com/2021/06/24/power-grids-hell-is-a-hot-still-summers-day/ Grid-scale batteries will tend to minimize…
Solar volatility: interconnectors versus batteries?
The solar energy reaching a given point on Earth’s surface varies by +/- 6% each year. These annual fluctuations are 96% correlated over tens of miles. And no battery can…
