… towards smart grids
• development decentralized power plants >> down–top
middle size GUD, CHP und Mini CHP
BIPV (building integrated PV) - with high direct electricity use …
• demand-site management (industry, large consumer, ..)
• „storage battery“ (e- mobility, ……)
• power to gas and power to heat
• „Buildings as power plant“
on the way to smart buildings …
