Abstract:

Use of wood fuel is a sustainable solution of district heating system development for the countries which do not have fossil fuel reserves, but have rich forest resources. The study analyses the options for wood fuel use in Latvia’s capital, Riga. The STATGRAPHICS Forecasting and regression analysis modelling tools were used to develop two possible forecasting curves showing the trend of wood fuel use until the year 2020. The results show that the share of the amount of heat produced by wood fuel in Riga could reach 25% of total heat demand if the current trend continues.

Abstract:

The paper discusses development trends of bioenergy production and use in Latvia.A methodology for the assessment of biomass potential was developed and applied to a Latviancase  study.  Four  scenarios  were  built  to  analyse  the  potential  of  biomass  supply  for  energyneeds  and  energy  costs.  The  biomass  resources  considered  are  forestry  residues  and  by-products, energy crops, and agricultural residues.The  evaluation  is  performed  on  the  basis  of  historical  data  analysis  and  literature  reviewapplying  indicators  with  sufficient  levels  of  information  aggregation  and  adequacy.  Futurebioenergy development patterns are assessed from technological, ecological and environmentalpoints of view. The analysis focuses on currently initiated cogeneration plant and boiler houseprojects  (planned  to  be  finished  in  two  years’  time)  and  maximum  available  bioenergyresources in country.The  analysis  indicates  the  biomass  potential  available  for  energy  needs  in  the  range  of  25–30 TWh per year in 2020, of which circa 15 TWh were used in 2011.  Key words: bioenergy, biomass potential, wood fuel.
