As reported in the latest issue of Pictures of the Future, Siemens and RWE are planning to use storage heaters to make surplus solar and wind power more usable. In the RWE Wind Heating project, the two companies have worked together with tekmar Regelsysteme GmbH to equip the storage heating systems in two neighborhoods with smart control devices. The storage heaters were programmed to charge their heat stores whenever there was too much sunshine or the wind was blowing. The test phase begun in 2011 has shown that the concept is very effective.
