AB - The Finnish energy industry is subject to policy decisions regarding  renewable energy production and energy efficiency regulation. Conventional  electricity generation has environmental side-effects that may cause global  warming. Renewable fuels are superior because they offer near-zero net  emissions. In this study, we investigated a heating mill's ability to  generate electricity from forest fuels in southern Finland on a 1-year  strategic decision-making horizon. The electricity-generation, -purchase, and  -sales decisions are made using three different energy efficiency and forest  technology rates. Then the decision environment was complicated by the  sequence-dependent procurement chains for forest fuels (below-ground) on a  tactical decision-making horizon. With this aim, fuel data of three forest  fuel procurement teams were collected for 3 months. The strategic fuel  procurement decisions were adjusted to the changed decision environment based  on a tactical techno-economic analysis using forest technology rates. The  optimal energy product and fuel mixtures were solved by minimizing  procurement costs, maximizing production revenues, and minimizing energy  losses.
