Siemens and Viridity Energy To Cooperate On Virtual Power Plants

Posted on August 13, 2009

As part of the move to convert existing power supply networks into smart grids, Siemens Energy and the American energy service provider Viridity Energy, Conshohocken, Pennsylvania, are to cooperate in the field of virtual power plants. The two companies have now concluded a technology partnership to offer power supply companies and network operators the necessary technology for implementing virtual power plants.

In a virtual power plant, various distributed power generation systems such as engine-based heating power plants, wind turbines, photovoltaic systems, biogas plants and small hydropower plants are combined into a network and controlled as a single power plant. The core element is a decentralized energy management system such as DEMS from Siemens. With DEMS, distributed generating plants can be networked into a smart grid and operated economically with less ecological impact. Network solutions from Viridity also offer market players functions that allow them to manage the availability of energy in the grid more effectively

A virtual power plant solution from Siemens and Viridity provides a more effective way to integrate distributed power generating plants into a power supply grid and represents a further step towards establishing a smart grid. The core element of the joint solution is the decentralized Siemens energy management system DEMS. This acts as the “brain” of a distributed power generator fleet, networking the individual power generation units and controlling them centrally. It thus helps them to operate economically and with less ecological impact, and to harness the full potential of a virtual power plant.

Using the Siemens decentralized energy management system, Viridity sets up virtual power plants adapted to the specific requirements of the operators. Energy efficient and ecological solutions for setting up smart grids are part of the Siemens environmental portfolio.
