LichtBlick is a large German utility that sells only renewable energy to their customers.
A couple of years ago they started rolling out “home power plants” (Zuhausekraftwerk) in cooperation with Volkswagen.
These are small gas burning units that use the heat for heating houses or providing hot water. This cogeneration process means that around 90 percent of the gas energy is used.
Now they announced that they are going to add Powerwall storage to their existing base of 1,000 home power plants.
They join a long line of other people who want to get their hands on these Powerwall units. Since LichtBlick will probably buy larger numbers, maybe they can get in front of that line.
