Tesla Powerwalls offer seamless home battery backup during any severe weather or outage. It is a fixed monthly resiliency package for storage paired with solar for extended backup power. This is a significant savings compared with the typical retail price of the systems. You receive this discount because you’ll be sharing energy with GMP during peak energy times (like heat waves) which helps to reduce costs (and carbon emissions) for all GMP customers. We use the clean stored energy instead of having to purchase costly, often dirtier, power during peak times and all GMP customers share the savings. If severe weather is in the forecast, we work to make sure you have the backup energy you need, in the event of an outage.
