Biogas Support Levels Compared to the Cost of Producing Electricity
I have put together this interesting graphic to depict what the different assumptions about support mean in the new Polish law being debated now. This does not reflect the value of heat sales or support for co-generation, which are critical to having a profitable project. It does show the relative inefficiency of smaller projects. The graphic also clearly illustrates the problem of buying substrates (such as grain or silage) and their very high contribution to the end price per kWhr. The values used cover a variety of scenarios. The 1.4 correction factor was the original Ministry of Economy proposal. The 2 factor is slightly lower than the IEO report recommended last year. The auction value would be the reference price (maximum in the auction) which will be lower somewhat, but not significantly since there will be too few projects below 1 MW to create real competition in the bidding as the proposal now stands. It is questionable whether the Polish proposed auctions can be approved ...
