A Texas company has recently announced a huge energy storage project, planning almost 5,000MW of power around the state. If successful, this would increase energy storage capacity by an order of magnitude, all while being on the same state grid.
This could be an interesting model for the UK. Texas is one of the few places in the US where transmission/distribution and generation are legally mandated to be separate. However, that model is ubiquitous in the UK. The business incentives proposed to make such a storage project economically feasible would make an interesting proposal for the UK as well.
The bottom line is that energy storage would solve a huge issue that currently hinders renewable power generation. A workable model on a grid the size of Texas could be a game-changer in one of the last major hurdles renewables have to widespread adoption.
Early last week, Texas transmission and distribution company Oncor announced a proposal to install 5,000 megawatts of battery energy storage on the Texas grid. The words “game-changing” get thrown around a lot about energy storage projects—usually prematurely. But in this case I think there are some clear reasons why Oncor’s proposed deal could be a game-changing development for grid battery energy storage:
