India Delays Coal Flexibility Plan Amid Rising Solar Power: What It Means for Energy Investors and Businesses
SINGAPORE: India has postponed by one year its initiative to reduce coal-fired power plant output during periods of high solar generation, as regulators work to establish compensation mechanisms for the increased costs associated with retrofitting these plants, according to official documents.
Experts warn that the lack of flexible coal power generation amid India’s rapid expansion of renewable energy capacity could undermine green investments, escalate compensation expenses, and result in higher emissions from coal use that could otherwise be avoided.
This decision comes as India, the world’s second-largest coal consumer, faces challenges with solar energy output reductions due to insufficient dedicated transmission infrastructure, while coal-fired plants struggle with operational limitations.
Solar power producers, instructed to curtail output because coal plants cannot easily reduce generation, may receive compensation estimated at up to $76 million for the eight months ending in December, according to the energy think tank Ember. These costs are expected to be transferred to consumers.
Government officials attributed the one-year delay to the absence of regulatory guidelines to compensate coal plants for the increased maintenance and retrofitting expenses necessary to lower the minimum operational level from 55% to 40%, as revealed in minutes from a January 16 meeting.
Retrofitting coal plants is projected to increase tariffs by 0.28 to 0.60 rupees per kilowatt-hour, significantly less costly than battery storage, which ranges from 5.76 to 6.04 rupees per kilowatt-hour. The Central Electricity Authority (CEA) highlighted that making coal plants flexible is at least ten times more economical.
In comparison, China’s more aggressive coal reduction plan introduced in 2023 has begun cautiously lowering the minimum coal plant utilization rate to between 25% and 40%, down from the previous 50% to 60%, to enhance renewable energy integration.
The Indian state coal operator NTPC warned at the January meeting about potential “accelerated wear and tear of critical equipment” when plants operate at minimum loads of 40%. It called for “detailed studies” to find ways to reduce usage without causing damage and noted that its new project contracts already include the 40% minimum operational requirement.
CEA officials responded that international examples demonstrate that coal plants can safely operate at lower output levels if properly retrofitted. However, the federal regulator has yet to approve the higher maintenance costs proposed by the CEA, citing a lack of sufficient operational data.
Senior officials from the federal power ministry, CEA, the federal regulator, the grid operator, NTPC, and the Association of Power Producers have agreed to assess the impact of the revised plan based on the latest cost estimates, according to the meeting minutes. — Reuters

India’s delay in retrofitting coal plants to enable flexible operation amid rising solar capacity highlights a significant challenge in integrating renewables cost-effectively. For businesses and investors in Oman, this signals the importance of prioritizing adaptable energy solutions and innovation in grid management, as rigid coal reliance may inflate costs and emissions. Smart investors should watch regional policies closely to capitalize on emerging opportunities in flexible clean energy technologies and infrastructure upgrades.
