About GTG Program


India plans to deploy unprecedented levels of renewable energy (RE) on its power grid, which can greatly reduce the economy’s carbon intensity and strengthen energy security. Compared to conventional power, India’s key RE options are more variable, less predictable, and often farther from demand centers. Experience in other systems has shown that when RE penetration reaches significant levels, the power grid’s capacity to manage that RE has to be addressed to avoid challenges to electricity reliability and affordability. Reliability issues could ultimately affect electricity end users, but are foremost a concern for grid operators, utilities, and RE investors.

Greening the GRID (GTG) Program

USAID/India is funding a five-year project to help India meet its ambitious RE targets. This project, known as Greening the Grid (GTG), is assisting the Government of India (GOI) in integrating large-scale, variable renewable energy (VRE) into the existing power grid. Critical to it is rigorous analytical support to identify grid stability issues, options for optimizing despatch, and sources of potential flexibility. Pilot projects are at the core of the GTG Program.

These projects are multi-implementer work programs aimed at testing and evaluating building blocks to improve RE integration into India’s state and national power grids. USAID/India’s GTG project combines three components, which interact with each other. These are:

  • Power system planning reforms and targeted analysis for large RE parks and RE integration pilots implemented by U.S. Department of Energy (DOE) Laboratories.
  • Renewable Integration and Sustainable Energy (RISE) initiative to implement innovation pilots, aimed at testing and evaluating building blocks to improve the integration of RE; and
  • Peer-to-peer exchanges between U.S.-India system operators (System Operator Partnership) and regulators (India Regulatory Partnership).
