Questionnaire to Review Current Activities and Associated Costs

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.

MEMBER STATE: PORTUGAL…………………………………….

Yes No 1. Do you collect data on domestic energy consumption? X O

1.1 If not, do you plan to start collecting such data? O O

When? ………

2. If you do collect data on domestic energy consumption, do you use:  survey(s) X O  administrative sources X O  modelling O O 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.

In Portugal we have two kinds of statistical information for domestic sector:

a. Administrative Sources/Questionnaires - Annually we collect statistical information from the main operators on electricity, oil products and natural gas about the consumption by activities sectors (CAE rev3 = NACE). This information is used on annual questionnaires and on Energy Balance. b. Survey - Periodically, which is not predefined, we carry on a more completely survey on energy consumption on households. The last survey was SECH2010, with the support of Eurostat and work together with INE (National Statistics Institute), which finished the data treatment in April 2011, and the reported was already send to Eurostat. Before this survey we have made in 1987 and 1996. With the SECH2010 we considered that we got a very complete set of indicators on energy consumption on households, according recommendations from WGES/Eurostat and IEA.

We go on to collect annually information from energy operators (electricity, oil products and natural gas).

About Survey on Energy Consumption on Households, our priority is concentrated on reduce the time between the surveys, and create a periodicity of 5 years. At the same time we are analyse the possibility that between this period (2-3 years) carry on a small survey with some main indicators, that allowed to do the evaluation on the consumptions. However, we stay yet in a early stage of this analyse. 2 4. For each survey or administrative source identified in section 3, complete the following questions, please:

10 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:

To estimate the total fuel consumption in households by type of fuel and end-use To estimate the breakdown of the fuel consumption by end-use To model electricity consumption for the different appliances

PORTUGAL don’t use modelling

5 Please, give the name and a short description of each modelling process used:

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.

11 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.)

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?

12 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.

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

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.
