WAL's next project: Implementation of the power supply system at the Tettau Water Treatment Plant begins
April 2021
Following the completion of the design for an independent medium-voltage power supply, the next phase of the project is now underway: E&A has been commissioned by the Lausitz Water Association (WAL) to carry out further planning and implementation for the Tettau water treatment plant.
The initial focus is on integrating the PV system and the energy storage system into the existing medium-voltage grid to ensure that the systems can be commissioned as planned in 2021.
Integration of PV components into the existing grid
As part of the first implementation phase, the feed-in system will be restructured: The medium-voltage feed-in cable supplying the horizontal filter well will be routed through a compact substation (skid-mounted substation). The medium-voltage output from the PV system and the storage unit will also be integrated into this substation. This creates the technical foundation for integrating renewable generation, the targeted use of storage solutions, and increased supply reliability during operation.
Scope of services provided by E&A in phase 1
For the implementation of the first project phase, E&A will provide the following services:
- Preliminary design
- Detailed design
- Preparation of specifications
- Assistance with contract award
- Construction supervision
E&A thus supports the project throughout its entire lifecycle – from planning to implementation.
Outlook: Expansion of the medium-voltage switchgear
In a second phase, the water treatment plant’s medium-voltage switchgear will be renovated and expanded. The goal is to fully integrate the PV system and the energy storage system into the entire medium-voltage grid and to implement an off-grid solution. This will make it possible in the future to operate the water treatment plant independently and stably in the event of a failure.
With this follow-up contract, WAL is consistently continuing its collaboration with E&A.
