E.DIS Netz GmbH

The 35,500 square kilometre grid area of E.DIS Netz GmbH spreads from the Baltic Sea coast to the edge of the Spreewald. In Fürstenwalde/Spree, Demmin and Potsdam one can find the three largest sites of the company, which fulfil important central management functions. Furthermore, the employees of over 40 sites work to ensure the reliable supply of electricity to the region. The company seat of E.DIS Netz GmbH is located in the city of Fürstenwalde/Spree. E.DIS Netz GmbH is a 100 percent subsidiary of E.DIS AG and is part of the E.DIS Group. The E.DIS Group offers many services through its other subsidiaries. These range from services in the field of heat and cold supply, the generation of renewable energy, services for electricity and gas grids and wind turbines, TÜV-certified call and other services to telecommunications. The E.DIS group is one of the largest employers of eastern Germany with around 2,500 employees.

Grid operation is organised in three regional areas. The company’s fields of activities are the distribution of electricity (Sparte Strom) through its power grid of about 79,000 km to large parts of Brandenburg and Mecklenburg-Western Pomerania, the distribution of gas (Sparte Gas) through the gas grids with a total length of approx. 4,600 km to the south of Mecklenburg-Western Pomerania and the north of Brandenburg as well as other activities in the electricity and gas sector.

The connection of renewable energy generating units and the integration of electricity from existing installations characterise the power grid operation of the company. Currently, about 8,800 megawatt from EEG units and about 800 megawatt from other decentralised generating units, in particular CHP units, are connected to the power grid of E.DIS Netz GmbH.

Through its tax and concession payments and dividends, the E.DIS Group makes a significant contribution to financing the budgets of towns and municipalities in the region.

Short description of the project contribution

Contribution to the flexibility platform, grid data transmission and CableEarth method

Within the scope of the ‘Innovative Process Platform’ workstream, a flexibility platform is developed to integrate the additional flexibility potentials in the redispatch process. The integration of these installations should be voluntary and free of discrimination. To that end, a web platform should be developed where installation operators, marketers or aggregators can offer their flexibility for specific locations or areas and can be procured by system operators in need of redispatch. The concept development involves the design of the web platform, the development of a prequalification procedure, the definition of products, the determination of the sequence for the bidding process, the communication of the flexibility potential including  coordination between grid levels, the call process as well as invoicing matters. E.DIS AG will contribute to the developments of this sub-project.

In addition, the effects of the growing share of renewable producers, storage units, electromobility and residual loads should be studied. The result is a contribution to the operating and optimisation strategy to minimise the need for grid expansion at the level of the distribution grid. E.DIS AG supports the project and provides the necessary grid data from the service area.

In another sub-project of WindNODE, the cable temperature and heat emission is monitored on a 110 kV cable route with a volatile renewable energy current load to determine the maximum current-carrying capacity using the CableEarth method. To this end, a 110 kV cable route of 30 km long in the E.DIS AG service area is constructed and equipped with the monitoring system in the Oderland district (Heinersdorf-Metzdorf) and taken into operation. This should identify transport reserves, taking into account the real-time forecast and temperature factor, as well as the optional actions for efficient route construction and operation.
