and excellent flexibility were the decisive factors in winning the latest order
from Stadtwerke Schwäbisch Hall. This public utility in Germany’s Swabia region
had already ordered a MAN 12V35/44G TS engine for an existing CHP power plant
back in 2017. It has now placed a follow-up order for an engine of the same
type. This will not merely increase the output of the existing co-generation
plant to a total of 15 MW, but
boost the facility’s efficiency too. Overall efficiency in CHP operation is in
excess of 90 percent.
technologies like CHP make a key contribution to generation controllability in
the context of the energy transition. Gas-powered CHP plants are also set to
become increasingly important in the future in view of the decision to phase
out coal, as their excellent overall efficiency means that they make best use
of resources and so have lower carbon emissions as well,” says Tilman Tütken,
Head of Sales Power Plants, Europe.
Highly efficient technologies like CHP make a key contribution to generation controllbility in the context of the energy transition.
The facility will operate in CHP mode for around
4,000 hours a year and, thanks to the existing district heating
accumulator, can also be disconnected from the heat grid and only used for
power generation. “This means that Stadtwerke Schwäbisch Hall can make optimum
use of the engine’s flexibility and respond to near-term price signals on the
electricity market,” says Tütken.
The MAN 12V35/44G TS gas
in the Schwäbisch Hall CHP plant
Hall is among the municipal trailblazers of the energy transition and
distributed power generation in Germany. In its supply area, it operates
numerous photovoltaic, wind energy, biomass and hydroelectric facilities, which
are perfectly complemented by flexible CHP plants. They generate around 267 GWh of electricity a year, covering around 70 percent
of demand in its grid area. The remainder is fed into the grid by companies who
also operate facilities in accordance with the German Renewable Energy Sources
Act. Stadtwerke Schwäbisch Hall achieved its original vision of covering all
its customers’ electricity requirements from renewable energies by 2030 well
ahead of schedule in early 2019 – thanks in part to having an innovative
partner like MAN Energy Solutions at its side.
