District heating plants across the Czech Republic are beginning to supply heat as temperatures drop, with conditions for the start of the heating season now being met in much of the country.
Some plants have already begun providing additional heat during the colder morning and evening hours. The first systems to respond were mainly in mountainous parts of northern and western Czechia and in the Vysočina region.
Other heating plants are expected to gradually start operating in the coming days, depending on local temperatures and weather forecasts.
Since 2010, district heating systems have generally started supplying heat after September 20, although the exact timing varies considerably from year to year.
If temperatures rise again in late September or early October, heating can be suspended. Under the standard rules, heating is normally interrupted when the average outdoor temperature exceeds 13°C for two consecutive days and the forecast indicates that temperatures will continue to rise.
Last winter was colder than average
The previous heating season placed greater demands on heating systems than the years immediately before it.
According to figures from the Czech District Heating Association, the season was 4.9 percent colder than the previous year. It was also 3.2 percent colder than the average of the preceding 15 years.
The colder conditions translated into higher demand for heat, particularly during periods of sustained low temperatures.
Heating costs could increase next year
Households are not currently expected to face a direct increase resulting from a recent change in the interpretation of a fuel tax exemption, but some other users of district heating could see higher costs.
The issue concerns combined heat and power (CHP) generation. This year, the state changed how an existing fuel tax exemption is interpreted, limiting its application to the amount of heat supplied to households.
Heating companies say the change could increase annual heating bills for institutions such as hospitals and schools by tens or even hundreds of thousands of Czech crowns.
