Control room as a building block for climate-neutral energy supply

They are causing sleepless nights for German citizens: buzzwords such as “energy transition in the building sector”, “heating law” and “municipal heat planning”. The switch to climate-friendly heating hangs over households like the sword of Damocles. Not so in Schwerin. The capital of Mecklenburg-Western Pomerania has a well-developed district heating network. In fulfilling the requirements of Minister Robert Habeck, Stadtwerke Schwerin is virtually “taking the burden off the shoulders” for a large part of the population. Schwerin is making great strides towards ensuring a sustainable energy supply. Innovative control station technology from JST offers perfect conditions for this decarbonization path not only now, but also in the future.

When the district heating network was built in the 1970s and 1980s, nobody could have imagined just how much the ongoing expansion of district heating would one day provide relief for a hot topic. Today it is clear: while the amendment to the German Building Energy Act is causing unrest up and down the country, around 65 percent of Schwerin’s residents can sit back and relax. The Federal Economics Minister’s demand also applies to them: the switch to renewable energies when installing new heating systems is mandatory (from 01.01.2024). However, as district heating customers, many Schwerin residents do not have their own boiler room. For them, the Stadtwerke take over compliance with the requirements from Berlin.

Schwerin gradually creates basis for "heating act"

A good reason for the local energy supplier not only to systematically expand the district heating network in Germany’s smallest state capital, but also to ensure that the necessary conditions are in place to exceed the government’s standards. The measures required for this are being tackled successively on site. One stage on the way to a sustainable and therefore climate-friendly heat supply: the new control room, which JST – Jungmann Systemtechnik® realized in cooperation with Stadtwerke Schwerin.

Energy supply: from geothermal sources to hydrogen

Fundamental modernization work has recently been carried out at the southern Cogeneration plant site: More efficient and at the same time more environmentally friendly gas turbines, which can also use proportions of green hydrogen for combustion, are just one element of the energy supply. “At the moment, natural gas is still our main source of energy. But our first geothermal plant is now going into operation and we want to continue along this path,” says immission control officer Thomas Vinzelberg, explaining the Schwerin concept, which also includes a supplementary biogas plant.

Control room bundles systems with flexible KVM technology

In other words, many individual building blocks to even exceed the legally required target of 65% climate-friendly energy supply for heat generation in the future. It is precisely at this point that the value of the investment in the new control room becomes clear, especially in the flexible KVM technology MultiConsoling®. The intuitive control room management system can be scaled effortlessly. New, renewable energy systems can be easily integrated. Thomas Vinzelberg: “The solution from JST is an optimal way for us to bring our different systems together in one control room.”

The team of boiler attendants quickly found their feet

The 30-strong team at the Schwerin control room has not only quickly found its way around the convenient real-time operation of its systems. Ergonomic furniture and the clear large-screen visualization are also highly appreciated by the boiler attendants.

Logbooks "are particularly interesting"

Division manager Klaus Rüger, responsible for the operation of the power and heating plants at Stadtwerke Schwerin, sees a particular benefit in the JST myLogin® solution. The software enables a lightning-fast login and logout process directly at the operator’s workstation. Limited authorizations are assigned via a keycard, but individual screen layouts are also saved, for example. “The traceable logbooks are particularly interesting,” says Klaus Rüger, “now we can track every single entry.”

Satisfied? Starting signal for control room no. 2

The experts for energy supply are convinced that they have taken an important step towards the future with the new control room and, looking back, praise the “high reliability” of the JST team. This satisfaction is backed up by another fact: Directly following the expansion at the South site, the go-ahead was given for a project at the Schwerin Lankow power plant site, which is also receiving a new control room with future potential in cooperation with Jungmann Systemtechnik.
