Description of the project

Ecotuning® project’s target was to reduce plant annual fuel consumption by 1% without any major investments. Any proposed investment payback time should be less than four years. Also the target in this project was to keep or even increase power production while keeping the heat production unchanged.

Power plants were modelled by using Fortum’s own power plant simulator (Solvo®). This ensured accurate calculation for each improvement impact on plant performance. List of improvements were established in co-operation with the customer. Each item profitability was calculated including action plan for implementation.
