I think that last part, of using BES at substations instead of adding transmission capacity is a point that is probably underestimated currently. If they place storage at local substations, you handle 4 different items concurrently. 1. Outages upstream to a substation can be temporarily mitigated by BES. 2. Pricing of peak power can be offset, saving the utilities money for residential and other non ToU customers. 3. Reduce the need for additional transmission lines. 4.Customers with solar/wind net metering have less of a power swing influence on the grid as a whole.There is more TE news, now from Australia
Lyndon Rive, who's position at Tesla is now head of energy products, was speaking on Thursday (yes, Thursday already happening down below) at the Australian launch event for PowerWall 2 and PowerPack 2. Here is the salient points reported by Australian publication REneweconomy.com:
- SA power crisis, which culminated in a large black-out event back in September, could be solved by adding 100-300MWh of storage, and Tesla is ready to help, in under 100 days (with the reference to the Mira Loma Substation project installed in 90 days). Rives indicated that Tesla is in negotiations with Australian utilities:
- Tesla has "big pipeline" of grid-scale battery storage projects
- Rives specifically addressed use of BES as a way to avoid building additional transmission capacity - an application that can have much better return than just time arbitrage or avoidance of peak charges.
I truly think that TE is a product that utilities really need, but they just don't know they need it. As such, BES is likely to really take off at the PowerPack level in the next few years as examples of success begin to penetrate the minds of the utilities. This is a great way to preserve profits.
