Basic Consumptions

• Until 2006 INE published monthly data in physical units on Electricity Production and Distribution. Statistics on Gas and Water Consumption were partially available from other sources.

• A project of monthly indicators for this sector was developed considering the preparation of the Index of Basic Consumptions covering Electricity, Gas and Water as it first phase.

4

• The second phase, to be ready during 2008 is to construct an Index of Electricity Production.

• The methodology has been prepared and its development is under way.

5

INDEX OF CONSUMPTION OF ELECTRICITY, GAS AND WATER

• The purpose of implementing this new short term indicator, is the measuring of changes in consumption of Electricity, Gas and Water by sector and region and for the country.

• The base period is the average of year 2003, and the source of data are the administrative records of the enterprises belonging to these activities.

Weight Calculation

In order to determine the relative weights a price average of year 2003, for each one of the basic breakdown of the indicator on each level is applied to annual consumption in physical units. The value of each level compared to the total is the relative weight of the level.

Electricity Consumption

The information on price of distribution of electricity by region was obtained from administrative records of the National Energy Commission. An average price for distributor was calculated

11

Gas Consumption• The information on average price of the cubic meter of natural gas and City gas by region was provided by the Electricity and Combustible Controller Office (Reference prices).

Consumo de Agua Potable

•The source of the average price of distribution of water information is the Superintendent of Sanitation Services, which provide peak (November through April) and no peak values (May through October) of cubic meter of consumption and sewage, plus the fixed charge per costumer. This information is given by company along with the number of costumers.

Methodology Summary• Index type: Laspeyres - Quantum• Base: Average 2003 = 100• Physical units:

– Electricity: Gig watt/hour of establishments distributors of electricity– Gas: Cubic meter of establishments distributors of pipe gas– Potable water: Cubic meter of establishments distributors of potable water

including cooperatives• Weights: relative prices year 2003 (To be updated every 5 years starting

2008)• Classification: Central Product Classification (CPC)

» Pipe Gas - 12020» Potable water – 18000» Electric energy - 17100

• Coverage: National and regional (15 Regions)• Periodicity: monthly (disseminated with two months delay due to delivery

time of the basic information from the sources: SEC and SISS)
