Heat as a Service

FersiSolar provides customised Heat as a Service solutions, enabling industrial customers to meet their process heat requirements without upfront investment in energy infrastructure. In this model, the client outsources the sustainable thermal energy production assets to a project company through a Heat Purchase Agreement (HPA), receiving reliable heat as a service with added value. FersiSolar and its project partners develop, finance, own and operate the installation, assuming the technological and operational risk.

Our solutions provide reliable solar heat supply, covering more than 50% of demand in temperature ranges between 82°C and 425°C, and are tailored to each client’s specific energy needs.

Our services include:

Complete project delivery

Development, design, financing, construction, commissioning, operation, and maintenance of the installation through strategic partnerships.

Process energy supply

Delivery of steams as an energy service, allowing customers to access renewable heat without owning or managing the asset. 

Energy optimisation and decarbonisation support

Solutions that reduce energy costs, improve efficiency, and support sustainability objectives, including access to green decarbonisation certificates.
