ENERGY CONSUMPTION IN HOUSEHOLDS
REVIEW OF CURRENT ACTIVITIES
This questionnaire examines the availability of statistics on energy consumption
in households in the Member States. It covers surveys / administrative sources
(Part A) as well as modelling activities (Part B), which may be used to make
these statistics available.
In addition to questions on coverage, the questionnaire examines costs, quality
and use made of the collected information.

Do you collect data on domestic energy consumption?
Yes
No

A stand-alone survey on this topic was carried out in 2010 (with 2009 as the reference
year) on a pilot basis.
Data are also available on:
(i) the amounts of electricity consumed by the domestic sector on the basis of
information provided by the Electricity Authority of Cyprus, which is the sole
energy producing enterprise in the country.
(ii) the quantities of petroleum products consumed by the residential sector
(estimates based on the monthly returns on the sales of petroleum products by
petroleum companies).

PART A: SURVEYS, ADMINISTRATIVE SOURCES
Part A reviews surveys and administrative sources used at national level. It
examines the availability of typical information normally made available by
such sources (the recommended coverage was used as benchmark), their
quality and associated costs.
3. Please, give the name and a short description of each survey and administrative source
used (include any planned survey, the description of which is already available). Include
information on collected statistics and users at national level. Indicate how this
information is used for policy definition / evaluation. Indicate additional priority user
requirements and associated statistics which should be made available in future data
collections to be carried out in your country.
The Statistical Service of Cyprus launched for the first time, during the fourth quarter of 2010,
an ad hoc survey on energy consumption in households. The financial assistance provided
by the European Commission (Eurostat) to the Member States interested in carrying out
such surveys was considered as a very good opportunity for further development in the field
of final energy consumption statistics, in line with the requirements of the Regulation on
Energy Statistics. The fundamental objective of the survey was to obtain a reliable estimate
of the final energy consumption of a typical Cypriot household by end use category.
The main statistics collected include: housing stock, household characteristics, consumption
/expenditure of energy commodities, space heating, hot water, cooking, electrical appliances,
air conditioning, penetration of renewable energy sources and energy consumption by end
use.

PART B: MODELLING ACTIVITIES
Part B reviews modelling activities carried out at national level. The questions seek
qualitative assessments and responses to a number of topics (source data, the modelling
objective and methodology, etc.) related to modelling and the associated costs. Three
types of modelling activities are considered, namely:
a) To estimate the total fuel consumption in households by type of fuel and
end-use
b) To estimate the breakdown of the fuel consumption by end-use
c) To model electricity consumption for the different appliances
5
Please, give the name and a short description of each modelling process used:
Some modelling work was carried out in order to estimate the breakdown of fuel
consumption by end –use (e.g. space heating and cooling and water heating) and to calculate
the energy consumption of various household appliances.
Please see the attached document named ‘Technical assumptions and estimations’ for more
detail.
7
6. For each modelling process identified in Part 5 please describe:
Model Name:…………………………….
1
Source data:
Give an overview of the key data sets that populate the model (surveys, administrative
sources, other models). For the various sources, indicate the frequency of the data collection,
an estimate of the robustness of the input data, and what other uses are made of the source
data.
The data collected from the survey was the source data. Some additional information such as
the electricity consumption values per appliance was obtained from various administrative
and other sources.
2
Modelling objective:
Specify the objective of the modelling process, in particular whether:
a) The modelling process is a bottom-up estimation of the total fuel consumption in
households (by fuel type and end-use). Specify the fuel(s) and end-uses (space
heating / cooling, hot water, cooking, lighting and electrical appliances) modelled.
Indicate any other relevant statistics (see recommended coverage in part A, point
4) which are part of the modelling output process.
b) The modelling process aims at providing disaggregated statistics by end-use, i.e.
the breakdown of fuel consumption for space heating, space cooling, water
heating, cooking, lighting and electrical appliances.
c) The modelling process aims at the disaggregation of electricity consumption in
households by type of appliance (oven, fridge, compact fluorescent lamps, etc.)
8
3 Modelling methodology
Please, provide a description of the modelling methodology (including a web-link to
published methodological papers). Indicate any external (independent) and internal reviews
and their frequencies. Indicate frequency of modelling updates to take account of new
technology (i.e. more energy efficient appliances) and new sources of data.
4 Reconciliation with other data
Please, provide an assessment of the accuracy of the modelling process of the overall
consumption in the bottom-up approach (case "a" above). Indicate how bottom-up estimates
are reconciled with aggregated energy balance data (supply side). What other independent
variables are used in the reconciliation process.
Provide as assessment of the accuracy in the case of the disaggregation of total fuel
consumption into the various end-uses (case "b" above). What other sources of data are there
to validate this element of the modelling against?
5 Uses of the model outputs
Please describe how the results are used to inform / monitor /evaluate national policy.
Describe the way the model outputs are published (internet, brochure, CD….), their frequency
and timeliness. Give links of most recent results.
The results of the survey on Final Energy Consumption in Households (which of course
include the model outputs) were published on the official website of the Statistical Service of
9
Cyprus. They were also sent to the Electricity Authority of Cyprus, for use in various
reporting obligations as well as for policy making and monitoring purposes.
6 Cost
Please give an estimate of the amount spent on:
-
setting up the modelling system (if done recently)
annual cost of purchasing data to populate model or additional cost of carrying out
surveys where the outputs are essential input for the modelling work
annual cost of model maintenance/development (staff, IT, etc.)
annual cost of reporting model results
As mentioned in part A above, the total cost of the survey reached €120.000. This amount
however cannot be broken down to identify specifically the cost of modelling.
7 Service responsible for the modelling
Please give the name of the service responsible for maintaining and operating the modelling
process. Indicate whether it is produced externally under contract.
The modelling process was carried out internally.
