  3. INTRODUCTION • The most frequently used and referred energy database for Malaysia is the National Energy Balance (NEB) which is published annually. • It was design to illustrate comprehensive statistical report on national energy supply and demand balance. • Fundamental input of the NEB is based on various data supplied by diverse range of data providers inclusive of relevant government agencies, power utilities, independent power producers (IPPs), private oil and gas companies as well as the cement iron and steel manufacturers.

  4. COMMODITY BALANCE • ..... a balance for each energy commodity that uses the units usually associated with that commodity. • Energy commodity can be either primary or secondary. • It shows the flow of the commodity from its sources of supply through to its final use.

  5. ENERGY BALANCE • Presents the commodity balances in a common unit and places alongside one another in a manner that show the dependence of the supply of one commodity on another. • some of the commodities are by product of others.

  7. ENERGY BALANCE MODEL

  8. ENERGY BALANCE MODEL • The overall energy balance is based on the simple accounting of the country’s total energy input and the total output using a common unit for the various forms of energy. For our country, the forms of energy are termed as energy products . Examples include, crude oil, natural gas, diesel, gasoline, LPG, LNG, electricity etc. • All energy products are converted into the common unit of Kilo Tonne of Oil Equivalent, ktoe, for the accounting of the energy balance

  9. ENERGY BALANCE MODEL

  10. COMPONENT DATA BALANCE REQUIREMENTS • To achieve a completely balance situation for every component in our model, each energy data contributor will be required to submit their set of energy data in the manner conforming to the input-output balance model described above. • Individual energy product imbalances will have to be captured as Losses under any of the 5 categories (flaring, operational, storage, transport, others) • It is important that this low level balance is achieved in the original units of measure (e.g. in kiloliters, metric tons or kilo barrels) as some discrepancies is expected when all the original units are converted into KTOE for all the energy products.

  11. STATISTICAL DIFFERENCE • The basic sequence adhered to in the overall balance is:- Production + Imports - Exports +/- Stock change = Apparent inland deliveries (or consumption) • “Apparent inland deliveries” deduced from supply statistics hardly ever match the actual sales data. It is necessary, therefore, to include two “statistical discrepancies” • the first to account for the difference in apparent inland delivery of primary supply mainly due to the difficulties in obtaining actual stock change data and difference in data compilation at source, and • the second to account for the difference in secondary supply as the result of the transformation processes of one form of energy to another. • the statistical discrepancies also act as a balancing tool to minimize possible errors.

  21. CONCLUSION • Malaysia Energy Information Hub(MEIH) http://meih.st.gov.my - a portal developed by the Energy Commission, aim to expedite data collection process & reduce human error. • It is a centralised system for two main users : i) data providers for data submission activity and; ii) the public for accessing the national energy related data. • The hub contained not only the time series of energy supply and demand balance but also the information on performance and statistics of electricity supply and piped gas supply industries.
