Taken from an article in REnewEconomy:
Investment bank Morgan Stanley says the global electricity utility industry is still underestimating the potential of EV maker Tesla to achieve a dramatic reduction in battery storage costs, luring more and more consumers to go off grid.
Tesla announced building a giga factory for manufacturing batteries. This could indeed turn the energy marked upside down.
For the US, Morgan Stanley predicts a tipping point that would cause customers to seek an off grid approach. They are setting three categories of how energy storage would be used:
- On the grid, but net zero grid power usage. Under this approach, a customer’s solar panels produce excess power during the day (which is sold back to the grid), and at night the customer draws power from the grid. This approach could result in low or net zero usage of power produced by large-scale power plants attached to the grid.
- On the grid, partial grid power usage. This approach is often taken in Europe, where solar panel systems are not sized to fully allow customers to eliminate their net usage of power from the grid, and where economics and regulation mean moving fully off grid is very unlikely. It is thus unlikely that such customers pursue a fully off grid approach.
- Fully off grid. In this approach, consumers fully depend on their on-site power generation, using storage and a power management system to provide power to the home when needed. Consumers could choose this approach for a number of reasons. For instance, in select markets, customers who choose to net meter as in the on-grid approach described above, have to pay a large non-bypassable, fixed grid charge; these consumers have an incentive to go fully off grid.
It seems that 1.) and 2.) fall right into the usage scenarios of the solar UPS controller. Hopefully the Tesla factory gets operational soon because sealed lead acid batteries are only the second best choice.
Another quote from the article:
Morgan Stanley says it is the scale of Tesla’s battery production, even for its own use as an auto manufacturer, that thrusts the company into ‘key player’ status for grid storage.
Tesla Model S (85 kWh) can store enough energy to power the average US household for 3.5 days.
