MNRE directs all DISCOMs to fast-track rooftop solar commissioning before June 1, 2026 ALMM-II cell requirement deadline
The Ministry of New and Renewable Energy has directed DISCOMs to fast-track rooftop solar commissioning.
The direction was issued through an Office Memorandum dated May 21, 2026.
It was addressed to DISCOM CMDs and MDs.
It was also addressed to heads of state electricity departments, state nodal agencies and chief electrical inspectors.
The objective is to expedite inspection and commissioning of rooftop solar PV projects before the ALMM-II deadline.
Projects installed or likely to be installed before May 31, 2026 need urgent commissioning.
Projects commissioned on or after June 1, 2026 will face stricter sourcing requirements.
They must mandatorily source both solar PV modules and cells from the ALMM List-I.
This makes the commissioning date commercially important.
A project installed before May 31 but commissioned after June 1 may face compliance complications.
The ALMM framework is a key domestic manufacturing policy tool.
Earlier, the focus was mainly on approved solar modules.
The June 1, 2026 transition brings solar cells into the compliance framework.
This is more stringent because cell manufacturing is more capital-intensive and technically complex than module assembly.
It also shifts demand toward integrated domestic manufacturers.
The OM is especially important for rooftop solar developers and consumers.
Many rooftop projects may already have modules installed.
But formal commissioning depends on DISCOM inspection and grid connection approval.
If these projects are delayed beyond May 31, they may fall under the new cell-sourcing requirement.
This can create legal, financial and inventory-related issues.
MNRE’s direct communication to DISCOM leadership is significant.
It suggests that inspection and commissioning backlogs are a major bottleneck.
Rooftop solar projects often wait for meter installation, inspection and grid synchronisation.
The Ministry wants these administrative delays cleared before the regulatory cut-off.
This makes DISCOM response critical.
The rooftop solar push is linked to India’s wider distributed solar programme.
PM Surya Ghar: Muft Bijli Yojana has increased rooftop solar momentum.
But implementation depends heavily on DISCOM processes.
Fast inspection and commissioning are necessary to convert rooftop installations into grid-connected systems.
The MNRE OM seeks to protect project momentum during the ALMM transition.
Developers using modules with imported cells face the highest risk.
Such modules may have been acceptable before the ALMM-II transition.
But they may not remain compliant for projects commissioned after June 1.
This creates urgency to complete pending inspections and commissioning before the deadline.
Inventory planning will become much more important after June 1.
For consumers, delays can affect subsidy timelines and project economics.
A project physically installed but not commissioned may not qualify under the earlier compliance treatment.
Consumers may face uncertainty if developers need to replace modules or prove compliance.
Faster DISCOM action can reduce these risks.
Domestic manufacturer benefit
The June 1 deadline benefits domestic cell and module manufacturers.
It increases demand for ALMM-compliant products.
Integrated manufacturers with listed cells and modules are likely to gain stronger market share.
This supports India’s domestic solar supply-chain strategy.
MNRE’s May 21 Office Memorandum is a clear administrative push before the ALMM-II transition.
DISCOMs have been asked to expedite inspection and commissioning of rooftop solar projects installed or likely to be installed before May 31, 2026.
Projects commissioned on or after June 1, 2026 must comply with stricter module and cell sourcing rules.
The key watchpoints are DISCOM commissioning speed, rooftop project backlogs, developer inventory risk, ALMM-compliant cell availability and the impact on rooftop solar installations after June 1.
