Energy Systems Analysis

The Celestial Earth’s core area of activity is related to energy systems analysis at national and sub-national level in India and other Asian developing countries. TCE’s in-house modelling capabilities extends from building national /sub-national energy systems model and implementing various policies to identify the medium to long term impacts of the same on economy, environment and society.

We use open source MESSAGEix ( Model for Energy Supply Strategy Alternatives & Their General Environmental Impacts) modelling framework to develop national and sub-national models.

Completed Projects


Developing Energy Plan & Action Plan for the State of West Bengal (2018-2019):

Developed the State Energy Model using MESSAGEix State Energy Model.


India Energy Model of NITI Aayog (2017-2019):

TCE team members were involved in developing the first India Energy Model using the MESSGAEix Modelling Framework at NITI Aayog. The project was to develop the India’s first energy systems optimization model using the MESSAGEix modelling framework under the research collaboration between NITI Aayog, GoI and IIASA.

On-Going Projects


Developing Low Carbon Technology Roadmap for SDG-7 Implementation Action Plan for South & South East Asia (2019- 2021):

TCE is developing the six country and four sub-regional energy models for six developing countries in Asia under the Asian Development Bank funding. TCE is the technical lead and the consortium member of the project implementation team working towards developing the strategy, road-map and action plans for implementing the SDG-7 targets in the respective regions and countries.

Water-Energy-Land Nexus

Resource constraint is an important policy impediment in today’s world. Developing countries are mostly affected due limited access to natural and financial resources to overcome the shortfall of adequate supply of resources. TCE is actively working in the field of resource conflict and nexus issue at the national and regional level in India and South Asia region.

TCE is committed to develop a modelling framework for the region in order to capture the resource nexus and redefining the sustainable development goals and objectives. India is the major focus country in this context.

TCE is the technical collaborator of IIASA on the project developing the river basin level integrated modelling framework of India. Developing basin level integrated modelling framework is a unique approach in terms of dealing with the water, energy and land use nexus in India.

On-Going Projects


Developing Basin Level Water-Energy-Land-use Nexus Modelling Framework for India (2019-2020):

TCE is collaborating with the International Institute for Applied Systems Analysis to develop the basin level energy-water-land use nexus model for India

Energy & Climate Change

Energy is one of the most critical sectors in the economy responsible for major share of emissions in the atmosphere. TCE is dedicatedly working in the energy sector and investigating various mitigation options linked to energy production and consumption. Transport and Residential/ Commercial sectors are the two major focus areas of work for TCE in the context of Energy-Climate Change interaction.

We have developed the transport-energy systems model for India capable of assessing the emissions impacts from transport sector in the country followed by various mitigation options including Electric Mobility. TCE has also developed the Urban Cooling Systems Model framework for India with detailed technology intervention in space cooling domain in the country. The Cooling Model is capable to assess the impact of energy use for various cooling technologies on climate change through GHG as well as Ozone depleting substances.

On-Going Projects


Developing Optimal Cooling Pathways for India and Implementation of ICAP (2019-2020):

TCE is developing the optimal space cooling pathways for India using the India Urban Cooling Energy Systems optimization model built on MESSAGEix platform.

Energy Calculator & Decision Support Tools

Energy modelling and output results highly depend on quality of data input, assumptions and analysis. Energy Calculator is an effective tool in terms of compilation of energy sectoral data and do scenario building exercise in a much simpler way using MS Excel. We are activity working towards developing the easy to handle energy calculator and model. Ease of operation of such tools can provide quick and necessary inputs to the users working with energy, environment and climate change policies.

TCE-DST is a step ahead in terms of making energy systems modelling even more easy in terms of creating own scenario and getting the results and analysing it compared to the baseline cases. This provides immense flexibility to the user to conduct multiple scenario analysis and take part in policy discussion with instantaneous results without having the model and knowledge of operation.

On-Going Projects


Developing the Decision Support Tool for India Energy Model of NITI Aayog, GoI (2019-2020):

TCE is developing the web interface Decision Support Tool for India energy Model of NITI Aayog which is built on the open source MESSAGEix modelling platform.


Updating IESS 2047 Ver.2.0 to Version 3.0 :

TCE is working on updating the IESS 2047 Version 2.0 to Version 3.0 with several new features and latest data of 2017-2018.

Capacity Building for Energy Modelling

Energy Modelling is important for policy making activities in today’s complex energy system in the country. However, energy modelling needs specialized training and capacity building for the model developers which is different from other modelling exercises. TCE is actively working towards creating the knowledge base of energy modelling across the country by conducting training and capacity building workshops and training programs.

We are currently having MoUs with the national institutes and universities to provide training and capacity building in energy modelling and application of energy models for policy analysis. MOU for Energy Modelling Training & Capacity building with

  • University of Petroleum and Energy Studies (UPES), Dehradun
