December 2000. Supplier of boiler house equipment was Dutch company
KARA Energy Systems. Building works were performed by local company
Valmieras SCO centrs.

11 Securing of biomass Initially agreement on wood fuel supply
was concluded between LBE and biggest local wood processing company
LINDEKS The contract term is 15 years Payments for the biomass were
made according to produced MWh of heat Fuel moisture 40-60% on wet
base On 2005 Lindeks reduced amount of output
Slide 12
12 Securing of biomass Payment for delivered biomass now is
made per loose cubic meter. Fuel moisture 20-55% on wet base. For
reduction of the risk related to only one supplier, we have agreed
that part of biomass is supplied by alternative suppliers the
biggest plywood producer Latvijas Finieris and other local
companies.
