enercity AG

enercity AG, headquartered in Hanover, is a provider of sustainable and intelligent energy solutions. With approximately €7.4 billion in revenue and over 3,500 employees (as of the 2024 financial year), the company is one of the largest municipal energy service providers in Germany. enercity supplies around one million people with electricity, heat, and drinking water. It is also among the leading players in onshore wind energy, municipal heat planning, and heating networks. Furthermore, the company offers a range of energy-related services, including in the field of e-mobility.

Mykolayivvodokanal

Founded in 1906, Mykolayivvodokanal supplied drinking water to around 486,000 residents of the city of Mykolaiv before the start of the Russian war of aggression. The average daily water demand exceeded 92,000 m³. Since the destruction of the main water pipelines by the Russian army in April 2022, the city's central water supply has been severely disrupted. Since then, water has been distributed through decentralised supply points, where drinking water is made available to the population. The distribution and maintenance of this infrastructure are managed by the municipal companies Dez Pilot and Mykolaivoblteploenergo.

Dez Pilot

The municipal company Dez Pilot operates approximately 100 decentralised reverse osmosis units in Mykolaiv. The treated drinking water is distributed free of charge to around 200 supply points across the city. Many of these facilities are located on the premises of public institutions such as schools to help maintain access to education.

Mykolaivoblteploenergo

The municipal utility Mykolaivoblteploenergo is primarily responsible for heat supply in Mykolaiv. Since the beginning of the war, it has additionally taken over around 80 decentralised reverse osmosis units to help provide the population with safe drinking water.

The project   

In response to the Russian war of aggression against Ukraine, enercity has initiated a solidarity-based operator partnership with the water utilities Mykolayivvodokanal, Dez Pilot, and Mykolaivoblteploenergo in the Ukrainian city of Mykolaiv. This cooperation also reflects the existing town twinning between Mykolaiv and Hanover, as well as the strong ties between the federal state of Lower Saxony and the Mykolaiv Oblast.

Since the destruction of the long-distance water pipelines in April 2022, the city of Mykolaiv has been cut off from a functioning drinking water supply. The piped network now delivers only salty technical water with poor quality, making it unsuitable for drinking or cooking. Residents are therefore forced to collect safe drinking water from decentralised distribution points across the city.

The salty water has caused extensive damage to the existing pipe infrastructure, resulting in numerous pipe bursts. A comprehensive renewal of both the water treatment facilities and distribution systems is urgently required. Until a central drinking water supply can be restored, the continued operation and maintenance of the decentralised reverse osmosis units remains essential.

Working packages of the Partnership  

One initial key work package has been identified as the primary focus of the partnership. As the collaboration develops, additional topics for mutual knowledge exchange will be jointly explored and implemented.

Procurement of equipment and material 

The aim of the operator partnership is to support the companies involved in Mykolaiv’s drinking water supply in procuring urgently needed equipment for the water supply system. By contributing technical expertise and practical experience in water infrastructure, enercity seeks to ensure that procurement processes are efficient, need-based, and cost-effective.

Mutual Transfer of Know-How on Core Issues

Alongside material support, another central element is professional knowledge exchange. enercity offers its Ukrainian partners technical consultancy, particularly on operational and infrastructure-related aspects of drinking water supply. The specific focus areas for this knowledge exchange will be jointly identified and developed as the partnership progresses.
