USES AND APPLICATIONS OF ENERGY STATISTICS:

1. USES AND APPLICATIONS OF ENERGY STATISTICS: • Measuring the Contribution of Electricity, Gas and Water - The Case of the Philippines - by VIVIAN R. ILARINA National Statistical Coordination Board Philippines International Workshop on Energy Statistics Beijing China, 24-26 September 2012

2. Outline of the Presentation • The System of National Accounts (SNA) • Measuring the contribution of Electricity, • Gas and Water in the economy • Scope and Coverage • Data and Data Sources • Estimation Methodology

3. The System of National Accounts • -consists of a coherent, consistent and integrated set of macroeconomic accounts, balance sheets and tables based on a set of internationally agreed concepts, definitions, classifications and accounting rules; • - use for monitoring the behavior of the economy, for macro-economic analysis, for economic policy formulation and decision making; as well as for international comparison.

4. The System of National Accounts • -basically, the SNA records all economic transactions, the flows and stocks in the country including its relationships with the rest of the world (ROW) • The SNA generates macro-economic aggregates namely: • GROSS DOMESTIC PRODUCT • GROSS NATIONAL INCOME

5. The System of National Accounts • In the SNA, transactors are economic units are grouped into producing industry/sector namely: • INDUSTRY – Agriculture, Industries, Services • SECTOR • Financial Corporations • Non-financial Corporations • General Government • Households including the Non-Profit Institutions • Serving Households National Statistical Coordination Board

6. II. Measuring the Electricity, Gas and Water SCOPE and COVERAGE Electricity, Gas and Water as an Industry Electricity - generation, transmission and distribution of electricity for sale to households, industrial, commercial and other users. Gas - manufacture and distribution of gaseous fuels through a system of mains to households, industrial, commercial and other users. Water - collection, purification and distribution of water to household, industrial, commercial or other users. Note: Scope and Coverage are based from the Philippine Standard Industrial Classification (PSIC) following the ISIC

7. II. Measuring the Electricity, Gas and Water SCOPE and COVERAGE Excluded are: - Operation of irrigation works in agriculture. - Electricity generation by manufacturing, mining and other industries for own use Note: Scope and Coverage are based from the Philippine Standard Industrial Classification (PSIC) following the International Standard Industrial Classification (ISIC)

8. II. Measuring the Electricity, Gas and Water DATA AND DATA SOURCES • Electricity • National Power Corporation • - Financial Statements • - Electricity produced and sold (peso&kwh) • - Other key performance indicators • Manila Electric Company and National Electrification Administration • - Financial Statements • - Electricity purchased and sold (peso&kwh) • - Other key performance indicators

9. II. Measuring the Electricity, Gas and Water • Electricity • Energy Regulatory Commission • - Effective Selling Rates • D. National Statistics Office • - Quarterly and Annual Survey and Census on • Philippine Business and Industry • Gross revenue • Employment • Compensation • Other key performance indicators

10. II. Measuring the Electricity, Gas and Water • Water • Manila Water Corporation, Inc. • Maynilad Water System, Inc. • Local Water Utilities Administration • National Water Regulatory Board • Financial Statements • Water production and sales statisticS • Effective selling rates • Other key performance indicators

11. II. Measuring the Electricity, Gas and Water ESTIMATION METHODOLOGY Benchmark Estimation • Gross Output (GO) • Revenue from main activity • Changes in Inventory of finish products and work in progress • Industrial and non-industrial services done for others • Trade margin • Changes in inventory of goods for resale • Other revenue • Fixed assets produced on own account

12. II. Measuring the Electricity, Gas and Water ESTIMATION METHODOLOGY • Intermediate Consumption (IC) • Materials and supplies purchased • Fuels purchased • Supplies and fuels used • Electricity purchased • Industrial and non-industrial services done by others • Other costs

13. II. Measuring the Electricity, Gas and Water ESTIMATION METHODOLOGY • Gross Value Added (GVAcur) at current prices • Compensation • Consumption of Fixed Capital • Taxes on Products and Imports • Operating surplus d. Gross Value Added Ratio (GVAR) GVAR = GVAcur /GO

14. II. Measuring the Electricity, Gas and Water ESTIMATION METHODOLOGY e. Gross Value Added (GVAcon) at constant prices GVA cons = GVAcur / Price Index where: Price Index = Constructed composite input price indices based on the prices of the major inputs (oil, fuel, diesel, electricity, machines and machine parts)

15. II. Measuring the Electricity, Gas and Water B. Quarterly Estimation a. Gross Value Added (GVAcur) at current prices GVA1cur = (GO1 / GOo) x GVAocur where: GVA1cur= present GVA GVAocur= previous GVA (the same quarter of the previous year) GO1 = present GO Goo = previous GO (the same quarter of the previous year)

16. II. Measuring the Electricity, Gas and Water B. Quarterly Estimation b. Gross Value Added (GVAcon) at constant prices GVA1con = GVAcur / WESR where: GVA1con = present GVA GVAcur = present GVA at current prices WESR = weighted effective selling rates

17. II. Measuring the Electricity, Gas and Water C. Annual Estimation Gross Value Added at current and at constant prices GVA = ∑ (quarterly GVA estimates) D. Price Indices a. Implicit Price Index (IPIN) IPIN = (GVA cur /GVA con) x 100 b. Inflation = growth of the IPIN from the same period of the previous year
