▷ Do not put solar district heating in the cold any longer!

In response to the explosion in heating and air conditioning costs, the solar industry recommends auctions for district heating solarization / Planned federal funding for efficient heating networks has been on hold for months and is underfinanced

According to the Bundesverband Solarwirtschaft e. V. (BSW) “a huge white spot on the map of the energy transition”. It is long overdue to cost-effectively leverage the enormous potential for climate protection lying fallow here with the help of modern solar collector fields. This requires a push program in the form of auctioned market premiums for solar district heating immediately after the formation of the government, according to the demand of the solar entrepreneurs. While photovoltaics now cover around ten percent of electricity consumption, not even one percent of district heating in this country has so far been supplied by solar power plants. Solar heat can now also be produced on an industrial scale for less than five cents per kilowatt hour.

The solar industry has recently registered growing interest from heat suppliers, but so far only a few dozen solar power plants for district heating feed on a megawatt scale are in operation in Germany. The reason for this is that the users of fossil fuels only have to bear a fraction of their health and climate costs themselves. The associated distortion of competition to the detriment of solar park operators is not compensated in the heating sector by appropriate CO2 prices or by appropriate subsidy offers, complains BSW Managing Director Carsten Körnig. A “federal funding for efficient heating networks” planned years ago has been on hold for a long time and is also equipped with a funding pot that is too small.

“The current heating cost debate must lead to a modernization, diversification and solarization of the domestic heating supply. It cannot be that solar district heating is kept cold and largely excluded from the heating networks. Solar heating must play a far greater role in the future – not only on the roofs from private homes, but especially on a large-scale, in order to feed into heating networks and thus bring emission-free solar heat into Germany’s inner cities, “says Körnig.

The Federal Association of the Solar Industry calls on the SPD, Greens and FDP to quickly close the profitability gap for producers of local and district heating. In order to wake up the “sleeping giant solar district heating”, the solar industry recommends, as a first step, a tender program for large solar thermal systems based on the model of the successful auctions for photovoltaic solar parks, which will run for at least five years. In this way, 20 billion kilowatt hours of emission-free heat could be produced particularly efficiently over 25 years. At the same time, the CO2 price in the heating sector should be increased more quickly and a citizen’s allowance should be introduced to compensate for social hardship. In addition, privileges for solar thermal energy are required under building law. Municipalities would find it difficult to provide areas for solar thermal power plants. Cancellations or years of delays have so far been the rule.

“Solar thermal energy offers an inestimable value for climate and consumer protection, namely reliable heating costs that are not dependent on any raw material or fuel – and that for decades. This climate protection technology is mature and immediately available. All that is missing now is the political investment impetus,” said Körnig.
