Energy Efficiency in Georgia

• EBRD from London has allocated 35 million USD for
  Energy Efficiency projects in Georgia
• Participating Banks TBC, Cartu Bank, Republic
  Bank
• Participating Banks approve the creditworthiness
  of the customer
• Energocredit supports these projects by
  evaluating and approving the energy efficient
  part and the saved energy.
• The resulted loans have short payback period (2-3
  years)
• The resulted loans are paid back from the reduced
  energy bills- no influence in the cash-flow of
  company

Energy efficiency mattersto businesses

• Energy efficiency can help companies
• Reduce energy and production costs
• Reduce exposure to rising energy
  prices/shortages
• Improve productivity and product quality
• Improve compliance with legislation and ISO 14001
  targets
• Improve environmental performance and reduce GHG
  emissions and waste
• Result
• 1. Same production for less cost
• 2. Increased production for same cost

5
Energy intensive Industry

• Energy Intensive Industrial Sub-sectors
• Food industry
• Glass and Ceramics
• Iron and steel
• Chemicals
• Oil refining
• Pulp and Paper
• Cement production
• Wood processing

6
Energy use in industry

• Energy Saving in Industries
• Active or efficient in-house management of energy
  consumption through maintenance and housekeeping
  measures
• Replacement of selected inefficient equipment
• Modification of entire manufacturing processes.

7
Typical examples

• Typical areas/systems where energy can be saved
• Variable Speed Drives (VSD)
• Boilers
• Space Heating
• Compressed Air
• Cogeneration (CHP)
• Renewable Energy Sources (RES)

8
Variable Speed Drives (VSD)

• Motive power
• More than 70 of the total site electricity is
  used for motive power
• Old systems have motors for fans and pumps, which
  are either on or off
• Now possible to control so they run at variable
  speed
• Match the motor output to the load required.

• Using VSD gives an energy saving of at least 30
• Lowering the speed of a motor by 20 gives an
  energy saving of 40
• The cost of a VSD for common motors (2-20 KW)
  equals the cost of electricity saved in a year

9
Boilers

• New condensing boilers take heat out of the flue
  gases, improving efficiency to more than 90
• Recovered heat can be used for intake water/air
  preheating or low temperature processes
• New boilers have controls for combustion oxygen
  to manage better combustion and operate
  efficiently in a wider load range

• New boilers can be organized in modules so
  supply matches demand

10
Space Heating

• In the light industry, space heating corresponds
  to 50 of the total energy consumption
• Central heating systems are more efficient than
  individual heating elements
• A reduction of 1?C on the thermostat 8 energy
  saving
• Use thermostatic valves by the heating panels
• Zoning also saves energy
• Use external compensating thermometer for the
  central heating

11
Compressed air

• Compressed air
• Compressed air is the most expensive energy
  commodity and should only be used as a last
  resort
• Question every use for compressed air
• Check leakages. A 3mm hole costs 500 GEL/year
• Check working pressure.
• A reduction of 1 bar 7 energy saving
• The cooler the intake air, the better.
• A difference of 4?C 1 energy saving
• It certainly should not be used for cleaning
  purposes.

12
Energy use in industry

• Cogeneration (Combined Heat and Power)
• Commonly used in industrial processes chemicals,
  paper, food, building materials
• Increased efficiency (80-85)
• In situ electricity/heat generation this reduces
  the losses incurred in the transport and
  distribution of energy
• Large cost savings
• Improved local and general security of supply
• Reduction of emissions, especially CO2
• Energy savings up to 30

13
Renewable Energy Sources (RES)

• Classical RES
• Wind power
• Solar power ( Hot Water, Electricity)
• Hydro power
• Geothermal
• Biogas production from agricultural waste

14
Solar Power

• Domestic Hot water
• Good number of degree days
• In Georgia
• Double circuit system ( glycol/water)
• Can be combined with the existing central
• heating
• Hydro
• Small size 1-15MW
• Cheaper
• Easy to Implement
• Up to 2 MW not regulated
• More ecological

15
The progress so far

• There are 10 projects approved by GEEP
• Total value of approved loans is
• 5.6 million USD
• There are 5 projects in the pipeline for approval
  worth around 9 million USD

16
Residential EE loans

• New product through the TBC Bank
• With 15 grant from BP
• Loans for installing
• Central Heating system
• Double glazing
• Solar Hot water boiler
• Wall- roof insulation
