In Sweden the potential opportunities include:
Norrbotten and Västerbotten have over 100 TWh unutilized technical potential of renewable energy and residual energy. The regional energy agency Energikontor Norr (energikontornorr.se) presented in cooperation with Luleå Technical University (LTU) a summary of the local assets of renewable energy in Norrbotten and Västerbotten. The result comprises 21 of 29 municipalities in the counties Norrbotten and Västerbotten. Behind the calculations is Joakim Lundgren, LTU together with Kjell Skogsberg, Energikontor Norr.
In addition to the 42 TWh per year that the 29 municipalities in the counties already used annually, the total technical renewable energy potential was estimated to approximately 100 TWh per year. In order to say how much of the potential is economically and environmentally possible and wisely to use, an in-depth work is required. The largest quantified energy potential in the NV Eko study is wind power of 43 TWh per year, based mainly on existing wind power plans. Since Piteå and Älvsbyn did not participate in that project, the wind farm in Markbygden- which is expected to go up to 1101 wind plants, has not been included in that figure.
The annual potential for natural and natural cooling has not been quantified at municipal level, but estimated to be at least 10 TWh for the 21 municipalities that participated in the NV Eko project.
Bioenergy comes in place three in the order of magnitude and accounts for just over 9 TWh. Hydroelectric potential was about 3 TWh due to increased water flows in the rivers caused by future increased precipitation and efficiency improvements.
For waste heat there is a low calculated potential of just over 1 TWh per year. Energikontor Norr has made a rough estimate of the combined potential of electricity from CHP in the 21 municipalities that participated in NV Eko, provided that all existing heat plants are converted to CHP and that small-scale bio-heat is being expanded in all urban areas that do not have district heating today. The combined potential of electricity from new CHP will then be closer to 2 TWh.
There is also potential for some TWh photovoltaic, depending on the size of the solar panels used, as well as a lot of solar heat. In addition, we should add potential for efficiency and exchange of electric heat to other heating, which can release additional TWh electricity for deliveries within or outside the region.
