At the current economic situation, it is necessary to ensure sustainable development of Latvia’s power sector, since now Latvia imports up to 70% of the required energy resources. The use of local biomass in cogeneration facilities would greatly increase Latvia’s energy independence. The paper provides the discussion of factors, and availability of local resources and competitive price for sustainable development of Latvia’s power sector. The least energy loss, when processing forest biomass, is monitored in the production of granules and woodchips. There is a great amount of energy-wood in Latvia. It is possible to produce 8 million MWh of energy per year if Latvia’s exported energy-wood is used in local cogeneration facilities. Properly and rationally processed logging scraps can be used to produce an extra 12.5 million MWh of energy, thus slightly decreasing the import of energy resources. Thermal energy producers using woodchips instead of gas can save up to LVL 456 per day to produce 1 MWh of heat. These thermal energy producers which use woodchips instead of gas provide lower heat tariffs and make rational usage of local resources possible, thus increasing Latvia’s energy independence.
