The Role of Electricity in the Economy and Philippine Energy Situationer

Flashcards covering global electricity trends, economic impacts, levelized costs, and the specific billing components and regulatory framework of the Philippine electricity sector.

PWh

Petawatthours, a large unit of energy measurement that quantifies total global electricity consumption over time, used to assess energy use history, growth projections, and sustainability in energy policies.

OECD

Organisation for Economic Co-operation and Development; an international organization that facilitates economic growth among its member countries and is predicted to generate a total of $13.9$ trillion kilowatthours of electricity by 2035.

Non-OECD

Refers to nations not part of the OECD grouping, where electricity generation is expected to increase at an average annual rate of $3.3\,\%$ from the years 2008 to 2035, indicating significant energy demand growth in these regions.

Levelized Cost of Electricity (LCOE)

A pivotal financial metric representing the average cost needed to generate one unit of electricity, inclusive of all financial liabilities like construction, operational expenses, and maintenance, allowing for comparisons between energy generation technologies.

Gas Combined Cycle

An advanced energy generation technology that employs both gas turbines and steam turbines to optimize efficiency and provide a reliable and stable electricity supply, making it a favored choice for reducing emissions.

Gas Peaking

A type of gas-fired power technology characterized by its quick-response capabilities, utilized primarily during periods of peak electricity demand, although it operates with lower efficiency than combined cycle systems.

BP Blg. 36

The legislative framework in the Philippines that establishes the rates for energy taxes based on households' monthly kilowatt-hour (kWh) consumption, influencing electricity pricing and energy revenue policies.

Generation Charge

The fee billed for electricity sold to the Manila Electric Company (Meralco) from various suppliers, including National Power Corporation (NPC), Independent Power Producers (IPPs), and the Wholesale Electricity Spot Market (WESM), making up a significant portion (over $50\,\%$) of consumer electricity bills.

Transmission Charge

The fee associated with transmitting electricity from power plants located in remote areas to the end-users via the distribution network, which is paid to the National Grid Corporation of the Philippines (NGCP).

Distribution Charge

This charge covers the costs of constructing and maintaining the infrastructure required to deliver electricity from high-voltage transmission lines directly to consumers, accounting for more than $20\,\%$ of the total electricity bill from Meralco.

Supply Charge

The charge that encompasses costs for customer-related services including billing, collection, and customer support, forming an integral part of the total electricity bill.

Metering Charge

Costs linked with providing metering services, which include reading and maintaining the meters that track electricity usage for billing purposes.

System Loss Charge

A cost recovery fee designed to account for energy losses incurred due to both technical flaws and non-technical factors; capped at $8.5\,\%$ for private utilities and $14\,\%$ for cooperative entities.

RA No. 7832

The Anti-Electricity and Electric Transmission Lines/Materials Pilferage Act enacted in 1994, originally establishing limits for recovery of system losses through electricity billing.

Universal Charge

A mandatory charge included in electricity bills that funds missionary electrification efforts and environmental initiatives; it is remitted to the Power Sector Assets and Liabilities Management Corporation (PSALM).

PSALM

The Power Sector Assets and Liabilities Management Corporation; a government entity responsible for managing power sector assets and liabilities and administering universal charges collected for electricity supply.

Lifeline Subsidy Charge

A fee charged to residential customers consuming above $100\,kWh$ per month, used to finance subsidies for low-consumption customers, ensuring affordable access to electricity.

Cross Subsidy Charge

A financial mechanism aimed at correcting under-collection in rates, supporting reduced electricity rates for low-income residential users and charitable institutions, which was mostly removed as of November 2006.

Senior Citizen Subsidy Charge

A nominal charge of $\text{P}0.0001$ per $kWh$ applicable to customers consuming beyond $100\,kWh$; the revenue is directed toward providing at least a $5\,\%$ discount for registered senior citizens on their electricity bills.

Luminous Efficacy

A quantitative measure of how effectively a lighting technology converts electrical power into visible light, expressed in lumens per watt ($LM/W$), crucial for assessing the efficiency of lighting systems.

GDP per capita

An important economic indicator that reflects the monetary value of goods and services produced in a country, divided by the total population, which helps to gauge the standard of living and economic productivity per person.

GDP (PPP)

Gross Domestic Product calculated on a Purchasing Power Parity basis; this measurement provides a more accurate reflection of economic performance by considering the relative cost of living and inflation rates between countries.

Integrated Gasification Combined Cycle (IGCC)

A cutting-edge fossil-fuel power generation technology that facilitates efficient energy production while being deemed suitable for incorporating Carbon Capture and Storage (CCS) systems to reduce greenhouse gas emissions.

Coefficient of Performance (COP)

A critical efficiency measure used for heat pumps, comparing the amount of heating or cooling produced for each unit of energy consumed, and is essential for evaluating emissions against traditional oil and gas heating systems.

PHEV

Plug-In Hybrid Electric Vehicle; a technology designed to enhance energy efficiency in road transport by combining traditional internal combustion engines with electric propulsion systems.

WESM

Wholesale Electricity Spot Market; a platform where electricity is traded, and from where Meralco procures power, allowing for dynamic price adjustments based on real-time demand and supply.
