Control energy market: Green electricity is used as a flexible minute and secondary reserve

The balancing energy market is often still one of the great unknowns for operators of decentralized, renewable energy systems. However, a stranger who has a great fascination and attraction. The comparatively young energy market for control energy there is growing interest especially from operators of biogas plants and wood power plants. Why? The strength of renewable bioenergy is its storability and the resulting flexibility. These are exactly the characteristics that are required for the provision of the Minute reserve and Secondary reserve in the balancing energy market.

Flexibility in the balancing energy market

A current release from Next Kraftwerke GmbH, which focuses on the Direct marketing of green electricity with a virtual power plant (Focus on bio-electricity). In another article you will also find information on the topics Market premium and flexibility premium, which are closely linked to direct marketing.

"Next Pool" virtual power plant approved in all control areas

Communication of the Next power plants GmbH from the 08.07.2013.

With the successful prequalification in the control areas of all four transmission system operators, the Cologne-based company Next Kraftwerke is entering Germany's market for control energy.

Since July 8.7.2013th XNUMX it is "Next Pool" virtual power plant Approved in all four control areas and then markets the flexibility of the connected decentralized power generators in southwestern Germany. In particular, biogas plants and wood-fired CHP plants are suitable for providing control energy from renewable energies and are accordingly strongly represented in the “Next Pool” virtual power plant.

Since the beginning of 2012, Next Kraftwerke has been able to prequalify a flexible system output of 119 megawatts for the minute reserve segment and 53 megawatts for the secondary reserve segment.

Hendrik Sämisch, founder and managing director of Next Kraftwerke, sees the successful Germany-wide approval as an important step for the company: “To our knowledge, we are the first virtual power plant for renewable energies that has entered the market in all four control areas. Our previous experience in the minute reserve and secondary reserve segments confirm that the producers of electricity from renewable energies are able to compensate for fluctuations in the German power grid. In the area of ​​the technically demanding secondary reserve in particular, renewable energies were often not expected to do this. However, the systems networked in our virtual power plant have proven in this segment in many secondary reserve calls that they are flexible enough to react to fluctuations in the power grid within seconds. ”

Amendment of the Renewable Energy Sources Act (EEG) in 2012  “Amendment of the Renewable Energy Sources Act 2012”), the way for renewable energies to participate in the control energy market was paved in order to promote the system integration of green electricity producers. The virtual power plant "Next Pool" networks the decentralized generation systems with control technology and then switches the connected systems according to the needs of the transmission system operator, whose task it is to ensure network stability. Renewable energies are already making a contribution to German security of supply by taking responsibility for system stability.
