In February 2015, the Government of India released its Renewable Electricity Roadmap 2030 for India at the first ever RE-INVEST summit in New Delhi, India. At the time, it was difficult to assess the economic implications—both benefits and costs (e.g. GDP, employment, etc.)—accruing to the nation. Equally important is understanding the distribution of these benefits and costs across the states given the geographic availability of energy resources. Conventional resources, such as coal, are available mostly in five eastern states, while renewables are available in the western and southern states. No publicly available and transparently documented sophisticated economic impact analyses framework—especially, that can conduct analyses at the state-level—existed in India in 2015. E3-India aims to bridge this gap. 

E3-India is a collaborative initiative by the Regulatory Assistance Project (RAP) and Cambridge Econometrics (CE) to support evidence-based policymaking in India. Developed with transparency and ease of access in mind, the comprehensive state-level model allows users to develop a shared and collective understanding of energy issues, creating space for consensus-based policy interventions. 

E3-India is available to all users, free of charge, under license for academic use to enable independent validation to inform policymaking. The model is vetted and updated through regular engagement with local experts and potential users.

The E3-India Model Provides


Regional coverage of 28 states and four union territories in India


General model of the economy, to assess a wide range of fiscal and general macroeconomic policies

of Impacts

Ability to evaluate the impacts of direct regulation on energy efficiency, feed-in-tariffs, direct subsidies, and energy and carbon pricing


Ability to assess the impacts of an array of energy and climate policies

How is the Model Being Used?

The academic and professional communities are applying E3-India, which has been in the public domain since mid-2017, to pressing policy issues. These include:

  • Analysing energy, emissions, and economy-wide impacts of adopting appliance efficiency measures;
  • Mapping impacts of power sector efficiency improvement, subsidy phase-out, and tariff rationalisation articulated by UDAY across Indian states;
  • Evaluating green grid scenarios (175 GW renewable energy by 2020) from the triple bottom line of economic, social, and environmental efficiencies; and
  • Allocating consumption-based environmental responsibility of coal production amongst Indian states, under the double dividend strategy for clean development.
