Wood Energy Contracting
Technical aspects

• A group of farmers build the heating system and
  the woodchips storage room for a big building or
  a group of buildings.
• They rent a cellar and install the heating
  central in the cellar of the building.
• They operate the installations and sell the heat
  to the user of the building.
• Heat rate is index-linked and a heat supply
  contract is signed for 15 years.
• The installation varies in size between 50 and
  250 kW.

11
Wood Energy Contracting
Organisational and legal aspects

• The heat supply cooperative sells the heat and is
  responsible for monitoring, service, repair and
  reinvestment of the system
• The heat consumer does not have any organisation
  tasks with the heating system
• The heat is billed on the basis of a set heat
  rate divided into a
• standing charge
• kilowatt hourly rate and
• metering charge
• Heat rate is index-linked and heat supply
  contract is signed for 15 years

From the idea to heat supply

• Feasible project
• Customer interest
• Analysis of ecnomic feasibility and
  financing
• Formation of a farmer group
• Rent agreement
• System planing
• Construction
• System start up
• Supply of energy
