Building innovative open-source tools to understand tomorrow’s power systems.

The Energy Systems Modeling (ESM) Initiative brings together researchers and practitioners to develop transparent, data-driven models that inform the transition to sustainable power systems.

Project Highlight


The GridPath-India model provides open-source models, datasets, and tools to help decision-makers plan energy investments that are reliable, cost-effective, and sustainable.

CETLab, in collaboration with WRI-India, Prayas (Energy Group), and government partners, is developing a multi-model framework to generate open, data-driven insights that inform energy policy and implementation across India’s national and state levels.

What we do

The ESM Initiative, develops transparent, open-source models that inform decisions on renewable integration, grid reliability, and low-carbon market design, delivering the evidence needed to drive a sustainable and resilient energy transition.
