No ALMM Exemption for Solar Projects Charging Storage

31 Jul 2025 CW Team

The Ministry of New and Renewable Energy (MNRE) has clarified that solar power projects installed solely to charge energy storage systems (ESS) will not be exempt from compliance with the Approved List of Models and Manufacturers (ALMM) requirements.

Solar installations that feed power to or charge an ESS which, either directly or indirectly, supplies electricity to the grid, will not be categorised as behind-the-meter (BTM) projects for captive use. As such, they will not qualify for exemption from ALMM compliance for solar modules.

MNRE reiterated that BTM classification is limited to solar projects used strictly for captive consumption by individual or group consumers, with no grid interaction.

Regarding ALMM compliance for solar cells, the Ministry noted that if the ESS is exempt from ALMM rules, then the associated solar project may also be exempt. However, if the ESS is not exempt, the solar plant charging it must comply with ALMM rules.

This clarification comes in response to stakeholder queries on whether private sector entities installing solar plants solely for battery charging purposes could qualify for ALMM exemption or be considered BTM systems.

In a recent update, MNRE stated that BTM projects developed by government bodies or public sector undertakings must still use ALMM-listed modules. However, such projects are temporarily exempt from ALMM compliance for solar cells if commissioned before 1 June 2026. Projects commissioned after this date must use ALMM-listed modules and cells.

Additionally, government projects mandated to follow ALMM guidelines for modules are exempt from applying the ALMM order to solar cells if the bid submission deadline falls on or before a designated cut-off date. The cut-off date will be one month following the publication of the first ALMM list for cells.

Smart Roads, Smarter India

India’s infrastructure boom is not only about laying more kilometres of highways – it’s about building them smarter, safer and more sustainably. From drones mapping fragile Himalayan slopes to 3D machine-controlled graders reducing human error, technology is steadily reshaping the way projects are planned and executed. Yet, the journey towards digitisation remains complex, demanding not just capital but also coordination, training and vision.Until recently, engineers largely depended on Survey of India toposheets and traditional survey methods like total stations or DGPS to prepare detai..

What Does DCPR 2034 Mean?

The Maharashtra government has eased approval norms for high-rise buildings under DCPR 2034, enabling the municipal commissioner to sanction projects up to 180 m on large plots. This change is expected to streamline approvals, reduce procedural delays and accelerate redevelopment, drawing reactions from developers, planners and industry experts about its implications for Mumbai’s vertical growth.Under the revised DCPR 2034 rules, buildings on plots of 2,000 sq m or more can now be approved up to 180 m by the municipal commissioner, provided structural and geotechnical reports are certified b..
