India may face significant evening power shortages by 2027, a California-based institute has warned.

The country may experience shortages ranging between 20 and 40 gigawatts (GW) if the electricity demand continues to grow at an annual rate beyond 6 percent, the India Energy and Climate Center (IECC) said. The situation is likely to arise even if all the currently under-construction thermal and hydroelectric capacity becomes functional as planned, the University of California institute cautioned.
