Priekules Novads, Latvia

This installation, built by HoSt, uses agricultural products and manure to produce sustainable electricity and heat.

Unique about this installation is that the input and mixing concept also allows difficult products like chicken manure, grass and straw to be digested.

The installation is built in 2 phases. In the first phase, in 2012, the capacity was 1.2 MWe, which was doubled to 2.4 MWe in the second phase in 2013. With this expansion, an identical digester was added, and the total efficiency improved by placing a second after-digester.
