Lehto Group Pursues Solar park partnership for Project with Substation
Lehto Group Plc has announced it is actively seeking partners for a significant solar park project located in Kalajoki, Finland. This strategic initiative represents a key opportunity for collaboration in the renewable energy sector, centered around the development of a solar farm complemented by a new electrical substation and a large-scale electricity storage facility.
Project Overview and Strategic Components
The project is more than a standard solar farm; it is an integrated energy development designed for future growth. Lehto plans to utilize existing agreements and rights to develop the site, which will feature two core components in addition to the solar park itself:
- A new electrical substation: This critical piece of infrastructure is designed to serve not only the solar park but also a planned electricity storage unit.
- A 30 MW electricity storage facility: To be constructed in two phases, this facility will enhance grid stability and maximize the value of the energy generated.
This combination of generation, storage, and robust grid connection infrastructure makes the Kalajoki project a forward-looking venture in the Finnish energy market.
Substation Capacity and Future Expansion
The planned substation is a cornerstone of the project, offering substantial capacity and scalability. Initially, the grid connection capacity will be up to 30 MW. This capacity is set to increase following the completion of a regional transmission line by the end of 2027.
Crucially, the project includes an option to expand the substation’s capacity to 100 MW, highlighting the long-term vision and potential for significant growth as the solar park and other regional energy needs evolve.
Development Status and Timeline
Lehto Group has already commenced design work, and the preparation of detailed technical plans is underway. The company has outlined a clear path forward, with several key milestones on the horizon:
- Q2 2026: Expected fulfillment of conditions for the final transaction, including securing building permits and the transfer of land lease and connection agreements.
- Late 2026: Potential start of construction activities on site.
- First Half of 2027: The electricity storage facility is projected to be operational.
Financial and Corporate Structure
The project will be financed through a combination of cash, project-specific loans, and installment plans from external investors. The electricity storage component will be funded through project-specific debt instruments, while proceeds from asset sales will cover the company’s restructuring debts.
Lehto Group Plc, based in Kempele, Finland, is spearheading this initiative as part of its focus on energy construction and real estate. Depending on financing requirements, specific subsidiaries may be established to manage the electricity storage operations. Lehto is now inviting cooperation partners to join in realizing the full potential of this comprehensive energy project.
