COGEN EUROPE RECOGNIZES STADTWERKE KIEL FOR MARKET DEVELOPMENT, GERMAN UTILITY’S FLAGSHIP PROJECT PR
Thursday, June 23, 2016

Source: General Electric

MILAN - GE’s Distributed Power announced that a 190-megawatt (MW) natural gas cogeneration plant being developed by municipal utility Stadtwerke Kiel in northern Germany has received a COGEN Europe 2016 Recognition Award for Market Development. The projected power plant will be powered by 20 of GE’s 9.5-MW Jenbacher J920 FleXtra gas engines, GE’s most powerful gas engine in its reciprocating engine portfolio.

The award was announced during the POWER-GEN Europe exhibition and conference in Milan. Andreas Halberschmidt, commercial project manager, Stadtwerke Kiel AG, accepted the award on behalf of Stadtwerke Kiel. POWER-GEN Europe hosts a comprehensive world-class conference program with an established legacy. This premier conference hosts leading organizations and high-level influencers at one of the most prestigious events in the power generation industry.

Expected to be available in October 2018, the new cogeneration plant will replace an existing older coal-fired power plant and supply the region with 190 MW of electric power and 192 MW of thermal power for the local district heating network. The new power plant’s total efficiency will be greater than 90 percent, and its electrical efficiency will be 45 percent.

As a nationwide unique project, the new cogeneration plant being developed already is considered a model, setting new flexibility, efficiency and environmental sustainability standards under Germany’s "Energiewende" transition to cleaner energy sources, including renewables and more efficient natural gas cogeneration systems.

The Stadtwerke Kiel project is divided into two phases. The initial project involves the planning and construction of the pump house to connect to the district heating system, the electrode boiler and heat storage as well as scheduling and obtaining operating approval for the entire system, including gas engines. The second phase of the project, including construction of the gas engine power plant, depends on the notification of the cogeneration law by the E.U. Commission in Brussels.

The 20 Jenbacher J920 FleXtra gas engines forming the heart of the plant will provide a great contribution to grid stability. The operating flexibility of the modular power plant enables it to provide balancing power, while the integration of an electrode boiler (power-to-heat) used during periods of surplus of electricity from renewables provides an extremely flexible and economical solution. This ensures not only the regional energy supply, but also guarantees operational cost-effectiveness. Compared with the previous coal-fired power plant, annual carbon dioxide emissions are expected to be reduced from 1.8 million tons to approximately 540,000 tons.

MTU ONSITE ENERGY GENSET AT STADTWERKE AMBERG SUPPLYING BALANCING ENERGY
Wednesday, June 22, 2016

FRIEDRICHSHAFEN, Germany - The local public utility in Amberg, the Stadtwerke Amberg, in Bavaria has been supplying load-balancing energy since June 2016 using a combined heat and power (CHP) plant from MTU Onsite Energy. This helps the network operator deal with unforeseen frequency variations in the power grid. The brand MTU Onsite Energy is part of Rolls-Royce Power Systems.

Dipl. Ing. (FH) Wolfgang Hüttner from Stadtwerke Amberg said: "Our CHP plant has been feeding power into the public grid system for one and a half years now, also producing heat for the local district heating system. We're now able to supply also positive and negative balancing power. These extra sales are an attractive business proposition for us, and we're pleased to be able to contribute in this way to making the power grid more stable and, as a result, performing an important contribution to the energy turnaround." The CHP plant is based on an MTU Onsite Energy 20V 4000 genset delivering around 2,000 kW of electrical power an approximately 2,200 kW of thermal energy.

MTU Onsite Energy and energy service provider EnerNOC are offering a joint solution to help genset operators run their systems more economically and market available balancing energy. Under this arrangement, MTU Onsite Energy CHP plants and standby gensets can be connected easily via an interface box to a virtual power plant. In that way they will help to balance out fluctuations in the power grid according to demand and availability.

Due to the gradual phase-out of conventional power stations in Germany and the expansion of renewable energies, it is becoming more of a challenge to keep the power grid at a constant 50 Hz. If more or less electricity is fed into the grid than the amount used, the grid has to be stabilized by means of load-balancing energy.

When the frequency has to be increased, power can be fed into the grid via the EnerNOC virtual power station (positive load-balancing). This can be provided, say, by standby gensets not constantly generating power. If the grid frequency is too high, the system can reduce the amount of electricity it feeds into the grid. This negative load-balancing is achieved by having bio-gas or natural gas-fired CHP plants reduce their otherwise constant output for short periods of time. Those operating MTU Onsite Energy CHP plants are now able to offer up to 80 percent of their rated power as negative secondary load-balancing power (instead of the customary 50 percent). Secondary load-balancing power must be supplied within five minutes.
