Environment
Dalkia uses the professional know-how it has gained through its long-standing operation in the energy service market, and contributes actively to the improvement of the environment in the Czech Republic through ongoing upgrades of equipment and cogeneration of heat and electricity. Dalkia Česká republika is certified to the ČSN EN ISO 14001 standard.
Principal rules that Dalkia follows in environmental protection
- Prevention of environmental pollution: seeking energy savings, reducing the number of local generating sources, development of district heating networks, etc.
- Heat and electricity generation in environmentally friendly cogeneration
- Replacement of increasingly larger amounts of coal with renewable and secondary energy sources
- Constant improvement, modernisation, and innovation of energy installations
New projects are notable for generating savings for Dalkia and its customers while being very environmentally friendly. Thanks to this, Dalkia has been successful in obtaining funding for its environmental projects from the European Union’s structural funds. Examples of environmentally friendly projects in line with the principles of the Sustainable Development Policy include the bio boiler in the Krnov heat and power plant, which fires 100% biomass, and the new TG4 turbine at Teplárna Olomouc that has helped to increase cogeneration of heat and electricity.

Cogeneration
A major pillar of the company’s strategy, combined heat & power generation, or cogeneration, is much more environmentally friendly than separate generation, as it supports improved efficiency of the installations and large fuel savings (up to 40%). Emissions are markedly lower as a result. Dalkia is No 1 in cogeneration in the Czech Republic.
Biomass firing
Dalkia constantly increases the percentage of renewable and secondary energy sources, in particular biomass, which is a strategic fuel of the future. In addition to the positive environmental effects, green energy production also positively influences the price of heat and electricity, and also local employment.
The most important sources of biomass include the green wood chips produced in timber processing, various vegetable residues from farming and from the food industry such as husks, residues from oilseed pressing, straw pellets, etc.
Dalkia started firing biomass in 2003 at Teplárna Krnov and added other fuels step by step. Biomass is currently used in, for example, Ostrava, Karviná, Frýdek-Místek, Olomouc, Kolín and Nový Jičín. 446,000 tonnes of biomass have been used for heat and electricity generation since 2003, replacing 518,000 tonnes of CO2. Dalkia’s goal in the Czech Republic is to increase the share of biomass in the fuel mix from the current 2.2% (in 2010) to 14% in 2016, which represents about 530,000 tonnes of fuel.
Dalkia is No 1 in cogeneration on the Czech energy market.
Dalkia has invested more than CZK 20 billion in the modernisation of its energy installations in the last 12 years.
