Enersense to modernise Sloka substation in Jūrmala, Latvia

The modernisation is necessary because the existing 6 kV switchgear building and electrical equipment have become outdated. As part of the project, some customers will be transferred to the 20 kV network, while alternative technical solutions will be provided to maintain electricity supply for the remaining customers. 

Enersense will be responsible for the entire project, from design and construction to commissioning. The work will include the construction of a new switchgear building, installation of 20 kV electrical equipment, a transformer and cable lines, as well as the dismantling of existing infrastructure and site improvements. 

The new electrical equipment and automation systems will help reduce technical losses, improve network resilience and enable faster restoration of electricity supply in the event of faults. 

“We greatly appreciate the trust Sadales tīkls has placed in Enersense. We are pleased to support the modernisation of the electricity network in Jūrmala and contribute to reliable electricity supply for local customers for years to come. As we will be working in an active urban environment, careful planning and the gradual transfer of customers to the new infrastructure will be particularly important,” says Kristaps Konrāds, Head of the MVL Department at Enersense Latvia. 

The project design is scheduled to be submitted in spring 2027, with all works planned to be completed by the end of the year. 
The contract has been recorded in the Power Business Unit’s order book for the fourth quarter of 2026.
