Russia’s District Heating:
Experience from the Transition
and Future Directions

Russian District Heating
Is regularly ignored, when energy and GHG mitigation policies are
discussed and determined, while
It accounts for over 31% of domestic final energy consumption in Russia,
and for over 32% of total fossil fuel use (more then electricity generation),
and
Is the largest single product market in Russia split into more than 50000
local markets with:
– US$ 33 billion annual sales, and
– US$ 50 billion efficiency improvement investments potential, but with only about
US$ 1-1.5 billion annual investments (it will take 30-50 years to release the
potential);
– at least 52% of the nation-wide potential for improve heat use efficiency and 1620% fossil fuel consumption and GHG emission reduction
Over 60% of district heat is consumed by buildings
Heat consumption went down in 1995-2000 and was frozen since up to
2006
The future for large CHPs in Russia is gloomy. The market for large CHPs is
squeezed by the competition vice
Given the shortage of meters, heat in Russia is still traded in the mist of
heat quantities and real costs
Large businesses have moved to the heat market

Heat supply systems design and
performance problems
Substantial supply overcapacity
Excessive estimates of consumers’ heat loads
Excessive centralization of small DHSs
Low density of heat loads and corresponding high level of
distribution losses in small DH networks
No regulation of heat supply parameters to balance with demand
at many sources
High distribution systems maintenance costs undermine the
competitiveness of small DHSs
Lack of standards for reliability, efficiency, quality of services and
economic affordability for consumers to evaluate the DHS
performance
Lack of incentives to improve efficiency and shortage of qualified
personnel, especially in small-scale DHSs

Operation of obsolete heat

High specific fuel consumption
Unsatisfactory metering of fuel consumption and heat
generation
Low remaining lifetime of equipment
Lack of regular boilers tuning
Low quality of fuel leading to failures of burners
Insufficient possibilities to regulate heat supply
parameters
Lack or poor quality of water preparation systems
High fuel costs
Shortage and low qualifications of personnel

Consumers’ behavior in the heat
market is poorly known
Uncertainty with the product on sale
Deprivation of households’ “market rights” to determine the
quality and quantity of product they buy and to negotiate the price
Substantial overbilling for heat, which was never delivered
Low heat meters and regulation devices saturation rate (below
15%)
Low flat-level water consumption meters saturation rate (below
15%)
Minor behavioral change in terms of hot water consumption even
after flow meters are installed and heat tariffs are growing
Poor insulation of buildings and insufficient development of
housing weatherization services
Lack of energy efficiency incentives where consumption is not
metered, or there are weak budget limitations
Limited ability and willingness to cover escalating energy costs
and strong opposition to any price increase

based on the benchmarking approach: reliability indicators, energy
efficiency, quality of service, economic indicators
Reliability, quality of service and prices as drivers behind the level of
centralization
Ability to translate performance indicators requirements into
municipal measures and actions to improve and modernize heat
supply systems in place with an account of energy efficiency as a
valuable resource
Checking for the ability to mobilize investments to realize the
proposed program
Shifting the affordability control focus from tariff to customers’
purchasing power. Energy costs for households have been staying
in the narrow range of 2-4% in many countries for decades

Energy efficiency improvements as an important
resource for municipal energy planning and launching
“profits-from-savings” mechanisms to generate
revenue source to repay DHS rehabilitation
investments
Transition, where necessary, to accounting for really
consumed and metered heat or comfort service, to
more accurate norms for consumers who are not
equipped with meters
Providing more operational freedom to DHS
companies and new system of interaction with
municipality
Clear evaluation of consumers’ purchasing power to
stay within the limits of affordability
