Energy year 2011 DISTRICT HEATING:
Use of renewable energy sources in district heat production exceeded 20 per cent for the first time
Finnish Energy Industries’ figures show that district heat sales fell last year by more than ten per cent on the year before. Consumption was down due to the milder weather than in the previous year. Adjusted for temperature, district heat consumption grew by more than four per cent. District heat sales over the year totalled 30.1 billion kilowatt hours (TWh), with a monetary value of EUR 1.93 billion.
Residential properties accounted for 55 per cent of district heat sales. At the end of the year, there were almost 1.3 million residential properties with district heating, with almost 2.7 million people living in buildings with district heating.
Most public buildings are connected to district heating networks. Almost half of the heating energy requirement for all our buildings comes from district heating. In the largest cities, more than 90 per cent of the heating energy requirement of the buildings is covered by district heating.
Volume of combined heat and power generation increased
Last year, the volume of district heat produced was 33.4 TWh. This is 13 per cent less than the year before, due to warmer weather conditions. Of the district heating, 74 per cent was produced in cogeneration with electricity, the share growing by 3 percentage points from the year before. Separate production of heat only covered 26 per cent of the production.
The volume of CHP electricity was 14.9 TWh. In combined heat and power generation, a third of the fuel quantity is saved compared to when they are produced separately. The emissions are reduced proportionally.
Carbon emissions down
Carbon dioxide emissions from district heat generation were 6.6 million tonnes, decreasing on the previous year by over 18 per cent. Most of the fall was due to lower production volumes than in the previous year, but also a result of increased use of renewable fuels. The average emission was 197 g per each kilowatt hour generated. The specific emission fell by almost six per cent.
Natural gas still most important fuel, use of wood up
Natural gas was used to generate 34 per cent of district heat and CHP electricity. Its share was down by just over one percentage point from the year before. The share of coal was 23 per cent. Its use fell by seven per cent, but the share rose by 1.5 percentage points. The share of peat increased by 1.5 per cent to 18 per cent. The use of wood, wood residue and other domestic renewable energy sources, such as biogas and secondary heat from industry, increased, and their share rose to 22 per cent. A good three per cent of district heating was produced from oil.
Mean price of district heat rose
The mean price of district heat inclusive of tax, including the energy fee and power charge, was 6.39 cents per kilowatt hour. The mean price rose by almost 17 per cent on the previous year. The price increase was particularly due to the rises in energy taxes at the start of 2011. Fuel prices exclusive of tax also rose during the year.
Taxes make up almost 30 per cent of the price of district heat. Generally, the principal factor influencing the price level is the size of the district heating system. In large conurbations, district heating is cogenerated economically with electricity. Other factors contributing to the price level of district heating include the fuels used, age of the plant, structure of the conurbation, efficiency of investments, and the owner’s requirements with regard to returns.
Reliability of district heat supply excellent
A district heat customer is likely to have his heating supply disrupted for 1.7 hours a year on average. The reliability of district heat supply is 99.98 per cent. The outages are caused by system breakdowns and repairing them. The work of connecting new clients to the network and moving pipelines in conjunction with roadworks may also cause supply interruptions. Most of the interruptions are planned, i.e. the clients are notified in advance.
Reliability of supply is excellent in Finland, even during spells of hardest frosts. Heating outages caused by faults in technical equipment usually affect a very limited number of customers, and they are brief. The high security of supply is the result of systematic quality control, upkeep and preventive maintenance.
The district heating production capacity is about 22,000 megawatts (MW). The maximum output requirement of clients connected to the district heating networks is about 18,100 MW.
