The new design for powering a GE plant in Berlin includes a 400 kW CHP gas engine and a 600 kW solar photovoltaic system with 200 kWh of battery storage. Germany has increasingly high volumes of solar on the grid, and so battery storage makes more and more sense there to retain that hard-earned energy. The flagship project shows off three of our favorite features in energy efficiency and clean technology. Let’s only hope that they replicate it, again and again.
GE Pilot Project Combines Solar, CHP, and Battery Storage
ACHR News, May 27, 2015
GE and project partners Kofler Energies and BELECTRIC announced they are putting a hybrid power plant into operation in Berlin that combines solar photovoltaic with combined heat and power (CHP) technology and battery storage. With an intelligent energy management system and comprehensive operational oversight, power output can be controlled to meet demands highly efficiently.
GE said the plant will not only supply power and heat to the GE Power Conversion production site in Marienfelde, Germany, but it also will feed power into the grid. The system is based on a scalable business model that also can be adapted for larger units.
The centerpiece of the hybrid power plant is a GE Jenbacher J312 gas engine with integrated heat storage and an efficiency level of 89.2 percent. The 400 kW system covers the basic heat load of the site during the heating season and is fueled by energy-efficient natural gas. The plant enables primary energy savings of around 30 percent compared to systems that generate heat and power separately through conventional heating and external electricity procurement.
