# Solar Power Type: Technology Source: Climate Intelligence Brief — https://getclimatebrief.com/entity/solar-power Canonical HTML page: https://getclimatebrief.com/entity/solar-power ## Timeline - **2030**: Target Achievement Year — All major targets set in the plan are expected to be met, including 3.5 billion kW installed capacity and 6 trillion kWh annual generation. - **2026-08-21**: BNEF Summit warning — Renewables Secretary Santosh Kumar Sarangi said projects without battery storage are unlikely to find buyers, with almost 42 GW of planned capacity yet to sign offtake contracts. - **2026-08**: GEM/CREA curtailment report published — Global Energy Monitor and CREA publish estimates showing 26.1% of China's combined wind and solar output was rejected, using weather-adjusted data. - **2026-07-23**: Plan Officially Rolled Out — China's National Development and Reform Commission and National Energy Administration jointly issue the 15th Five-Year Plan for renewable energy development. - **2026-07**: NEA reports official H1 curtailment rates — The NEA states 8.6% of solar and 9.1% of wind output was curtailed in the first half of 2026, far below independent estimates. - **2026-06**: China curtails 360 TWh in first half of 2026 — China rejects 360 TWh of wind and solar output from January to June, up 49% year over year, per GEM/CREA. India curtails 8.13 TWh of solar in the same quarter. - **2026-05**: Solar surpasses coal for first time — Solar supplies 12.8% of U.S. electricity vs. coal's 12.2%, marking a historic inflection point. - **2026-05**: Peak curtailment during record demand — Scorching heat sent electricity use to an all-time high, and grid curtailment hit its highest level of the quarter. - **2026-04**: Q2 curtailment period begins — During April-June, India's transmission system failed to absorb more than 8 billion kilowatt-hours of power after 63 billion kWh actually reached the system. - **2026-03**: NEA halts monthly provincial curtailment data — China's National Energy Administration stops publishing monthly curtailment data by province, reducing transparency around grid performance. - **2021**: Solar holds 5.4% share — Solar power accounts for just 5.4% of U.S. electricity generation, while coal still provides 19.7%. - **2016**: Natural gas becomes top U.S. power source — Cheaper and more efficient natural gas overtakes coal as the primary fuel for electricity generation. ## Recent coverage (4 stories) ### India Lost 11% of Peak-Season Solar to Curtailment; 42 GW Needs Storage Deals 2026-08-21 14:45:47 · Sentiment: Positive · Impact: 6/10 · Sources: 2 India's rapid solar expansion is outrunning grid capacity, causing 11% of peak-season generation to be curtailed even as demand hit records. Battery storage is becoming a requirement, not an option, for the 42 GW of planned projects still lacking offtake deals.

With curtailment now spreading to India, Australia, and Japan, vast zero-carbon generation is being left unused even as China's coal generation rebounds.

This inflect point reflects a near-doubling of solar’s share in five years and signals accelerating decarbonization. The milestone underscores the viability of renewable energy and its growing role in climate goals.
