Enabling a distribution network in the Czech Republic to reduce monthly payments and avoid penalties
Wattstor partnered with Ista Solar to create a battery and solar system for an electricity distribution network. The seamless solution delivered intelligent storage to ensure it transmitted electricity within grid constraints, avoiding high penalties.
The KD Energo EMS Project Challenge
KD Energo is a network distribution company in the Czech Republic. The main activity of the company is the production, distribution and sale of energy in the industrial area in Králové Dvór and its immediate surroundings.
- ENERGO KD is connected from the Tetín substation at the 110kV level.
- Two 22 kV lines with a transmission capacity of 22 MW lead from the Tetín substation.
- The supply lines are led to the input substation with three transformers 22 / 5.25 kV, 6.3 MVA.
- A backup line with a transmission capacity of 2 MW is available.
The partner – Ista Solar
Ista Solar builds custom-made power plants from cutting-edge technologies with a combined 25-year warranty for the entire system. The long service life and full functionality of the system will ensure the production of electricity for decades.
The customer has a local distribution system, where they have high peak-demands, therefore the distribution network has to pay for higher reserved capacity or face penalties for crossing the reserved capacity.
The interesting part about this particular project is that due to the nature of the network, the 2 battery energy storage systems (BESS) are located 10km apart, along with a solar PV installation for charging the batteries when required.
Wattstor’s combined EMS and energy storage controls the demand for electricity and injects power from batteries whenever it is needed through peak-shaving applications.
Wattstor installed the solution over the course of 2 days in 2 separate phases. We worked with ISTA Solar, who did the physical installation, while Wattstor delivered the system intelligence (EMS/BESS), covered the logistics of the project, collaborated on the design and commissioned the system on site.
