Improving energy efficiency

Energy efficiency is a key factor in energy production – from both an economic and environmental perspective. Improving energy efficiency at power plants refers to measures we implement to increase the efficiency of production processes or reduce the energy consumption of plants or equipment. This enables us to produce more electricity or heat for our customers without increasing fuel consumption.

The energy efficiency of power plants can be increased through investments and technical improvements, preventive maintenance, and by training personnel in the optimal operation of the plant and in monitoring the plant’s operating economy. Improving power plant availability also increases energy efficiency, as unplanned plant start-ups are reduced.

Energy-efficiency investments

In fuel-based energy production, we aim to utilise the fuel’s energy as efficiently as possible. Our most important means to improve the energy efficiency of fuel use is to increase combined heat and power (CHP) production. In CHP production, up to 90% of the energy content of the fuels can be utilised. Separate electricity production’s efficiency is about 60% at best. 

Target within reach

Fortum is participating in the European electricity sector’s Energy Wisdom programme. We report to the programme on significant projects that improve energy efficiency and reduce greenhouse gases. Fortum’s target is to achieve an annual energy savings of more than 1,400 GWh by 2020 compared to 2012.By the end of 2016, about 1,372 GWh or 98% of the target set for 2020, had been reached.
