Integrated Energy Planning

Integrated energy planning is the coordinated assessment of how a country can meet its demand for energy services across sectors and fuels. In a national power system, it jointly plans demand, generation, networks, storage, fuel availability and environmental constraints instead of treating each component or energy source separately.

Scope and planning method

Planning begins with projections of demand for energy services under alternative assumptions about economic growth, technology, prices and efficiency. It then uses scenario analysis to compare combinations of generation, networks, storage, fuel supply and demand-side measures over a long-term horizon.

• Demand forecasting must cover households, agriculture, industry, transport and commercial activity rather than extrapolate electricity consumption alone.
• The assessment considers coal, hydrocarbons, nuclear power and renewables, including possibilities for substitution among fuels and electricity.
• Generation expansion is planned jointly with transmission and distribution, because capacity without adequate networks cannot provide reliable supply.

Objectives and trade-offs

The preferred pathway seeks reliable energy services at the lowest overall economic and social cost, rather than merely selecting the cheapest generating plant. It balances energy security, affordability, universal access, technical efficiency and environmental sustainability.

• Planning accounts for domestic resource availability, import dependence, fuel-price risks and supply disruptions.
• It values energy efficiency and demand-side management as alternatives to additional generation.
• It incorporates system flexibility, balancing requirements and reserve capacity needed to integrate variable renewable energy.
• It considers pollution, land, water and greenhouse-gas implications when comparing technological choices.

Institutional coordination and review

Integrated planning requires common data, assumptions and objectives across energy ministries, regulators, utilities, fuel suppliers and governments. Integration means coordinated decisions and regular review, not necessarily administration by a single ministry.

• Under Section 3(4) of the Electricity Act, 2003, the Central Electricity Authority prepares the National Electricity Plan in accordance with the National Electricity Policy and notifies it once every five years.
• Implementation must align investment, fuel linkages, network development, pricing signals and efficiency programmes, with plans revised as demand and technology change.
