The Tamil Nadu Electricity Regulatory Commission (TNERC) released its draft multi-year tariff (MYT) regulations for distribution licensees (DISCOMs) covering financial years 2027-28 to 2031-32. Stakeholders can submit their feedback by May 27, 2026. The draft replaces the 2005 and 2009 tariff regulations for DISCOMs, which were framed when generation and distribution were within the erstwhile Tamil Nadu Generation and Distribution Corporation.

In Q1 2026, India achieved a significant milestone, generating approximately 52 billion units (BU) of solar power, registering a 24.3% year-over-year (YoY) increase, as reported by the Central Electricity Authority. Solar generation also recorded a 27% quarter-over-quarter increase from 41.1 BU, highlighting positive momentum. Solar installations in the country increased by 48.8% YoY between the first quarter (Q1) of 2025 and Q1 2026.

The transition to green energy continues to accelerate in India, driven by policy support, declining solar technology costs, and rising electricity demand across commercial, industrial, and residential segments. The growth trajectory of India’s solar industry is creating opportunities for manufacturers, engineering, procurement, and construction firms, and solution providers while also increasing competition among suppliers.

The Himachal Pradesh Electricity Regulatory Commission issued the draft Promotion of Generation from the Renewable Energy Sources and Terms and Conditions for Tariff Determination (Eighth Amendment) Regulations, 2026, which seeks to add definitions of biomass and introduce new timeframes for ‘Useful Life’ across different renewable energy categories. Stakeholders have 30 days to submit their feedback.

TNERC approved tariffs in the range of ₹3.02 (~$0.0315)/kWh to ₹3.09 (~$0.0323)/kWh for the procurement of 12 MW of solar power under Component-A of the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan program.

NTPC invited bids for an engineering, procurement, and construction package to repower its 5 MW NTPC Andaman solar project at Garacharma in Port Blair. The scope includes the supply, erection, testing, and inspection of equipment and materials at the manufacturer’s works; packing, supply, and transportation; transit insurance; delivery to site; unloading; storage; and equipment erection, including associated civil and structural works. The last date to submit bids is June 2, 2026. Bids will be opened on June 4.

The Grid Controller of India suggested to the Central Transmission Utility that all new battery energy storage systems (BESS) above 50 MW be mandated to have grid-forming capability at the time of granting connectivity. The measure, to be in place until the Central Electricity Authority’s Construction Standards for Renewable and BESS are notified, will ensure adequate system strength for reliable system operation while granting non-solar hour connectivity at existing pooling stations.

Nextpower (previously known as Nextracker), a solar PV solutions provider, entered into a definitive agreement to acquire complementary assets of Zigor Corporation’s power-conversion business and its U.S.-based subsidiary, Apex Power. The transaction is expected to expand Nextpower’s product portfolio and capabilities in utility-scale solar power conversion.

Large commercial and industrial consumers are increasingly turning to solar power to meet sustainability goals and reduce their electricity expenditure. Businesses with continuous power demand can achieve significant savings by utilizing unused rooftop space for solar installations. Maharashtra-based textile fabric manufacturer G.M. Syntex is saving approximately ₹40 million (~$420,248) annually after installing a 3 MW rooftop solar project.

Clean energy solutions provider Clean Max Enviro Energy Solutions’ income for Q4 of the financial year (FY) 2026 rose 29.2% YoY to ₹6.40 billion (~$66.90 million) from ₹4.95 billion (~$51.79 million). Revenue from the renewable energy sales rose to ₹3.69 billion (~$38.60 million) from ₹2.87 billion (~$30.02 million) a year earlier.

Gujarat-based Torrent Power posted revenue of ₹64.06 billion (~$673.03 million) in Q4 FY 2026, down 0.8% YoY from ₹64.56 billion (~$678.28 million). Revenue growth from the renewable energy segment was partly offset by higher interest and depreciation costs. Contributions from the gas-based generation business remain constrained by dynamic power demand and gas market volatility.

U.S.-based solar tracker company Array Technologies reported revenue of $223.4 million in the first quarter of 2026, down 26% YoY compared to $302.4 million. The revenue exceeded analysts’ expectations by $21.75 million. Adjusted earnings before interest, taxes, depreciation, and amortization came in at $28.8 million, down from $40.6 million in the corresponding period last year.

U.S.-based residential solar and battery storage provider Sunrun reported a revenue of $722.2 million in Q1 2026, increasing 43% YoY from $504.3 million. The revenue beat analyst expectations of $688.5 million. Profit after tax stood at $167.6 million, up 235.2% YoY from $50.01 million. Earnings per share came in at $0.62, compared to $0.2 in Q1 2025. It beat analyst expectations by $0.67.
