Demand Side Flexibility in Production
Understanding flexibility and means of control
High speed balancing facility (gas turbine plant)

Type of flexibility:

Example: Preferred control for balancing facility

Include availability of renewable energy into productionplanning Time frame ~ 3 days
Show current energy availability at production machinein order to provide flexibility to operator
 Time frame ~ 3 hours

Load profile – high speed balancing

Closed loop control of production equipment based on
current renewable energy availability
 Time frame ~ < 1 min.

Optimization process

One optimization per grid connection
 Input: Price time series, flexibility time slots,opportunity costs
 Minimize target function: Total costs (powersupply, network access, opportunity costs)

Brazing furnace with 3 typical production related load profiles

 Degrees of freedom: Load profile of flexible
processes („typical“) can be shifted within the timeslot. Max. power restrictions not to be exceeded.
 Results: Starting times of flexible processes andload forecast

Combining Expertise in Renewables and Hydrogen
Outlook for a region with “energy & transition” expertise
Examples for potential future projects in East Germany

Lignite regions

Power-to-Gas. Government have recently launched their callfor “Reallabor“ applications (“reality labs“ = showcases at ahigh Technology Readyness Level) with a focus on Power-toGas**. Up to EUR 100 mio. funding per year. Reference Plant
Lausitz selected for realization.
Phasing out coal. Most likely, lignite will be phased out by2038. Strong political attention for a major transformation
effort. Currently, there is intensive discussion on perspectives
for former coal regions. Hydrogen & sector coupling as
promising approaches.

** Call by BMWi (Federal Ministry for Economic Affairs and Energy) is available online (only in German):

Driver and barriers for industrial load management

Energy costs are small compared to total production costs (processes looked at above)

Barriers

High implementation effort (change in manufacturing setup)
Future competition: Flexible power applications, e.g. e-mobility, P2G and power storages

Increase of renewables installation/ decrease of controllable power generation
New energy services (e.g. flexible electricity tariffs)

Drivers

Flexibility friendly or obligate regulation
Synergies with predictive maintenance and energy efficiency measures
Increasing digitalization of production
Increasing demand of carbon neutral power
