MHA Border Solar Ban: 1km Zone, 50km Clearance

Quick Answer

Why This Matters for EPCs

This isn't a niche restriction affecting a handful of remote projects. Rajasthan, Gujarat, and Ladakh, three of the country's most active solar and wind development corridors, sit substantially within the 50km sensitive zone this rule creates. Any EPC bidding on land in these states now needs to know exactly where a site falls relative to the border before quoting a timeline, because a project 2km from the border and one 40km from it face genuinely different approval paths.

What the Guidelines Actually Say

The Ministry of Home Affairs, through its Internal Security wing, issued formal guidelines for national security clearance of solar, wind, and hybrid renewable energy projects in border areas. The guidelines trace back to an MHA office memorandum dated June 5, 2026, issued after MNRE reported a growing volume of applications for renewable projects in border regions carrying potential national security implications. The formal Standard Operating Procedure was circulated to the Ministry of Defence, MNRE, the Intelligence Bureau, the Border Security Force, and the Gujarat government specifically.

The core structure has two zones. Within 1km of the LoC, LAC, or International Border, the area is designated a "restricted area" where no project activity is permitted at all, an absolute ban, not a clearance requirement. From 1km out to 50km, the area is a "sensitive area" where every solar, wind, or hybrid project requires case-by-case security clearance from MHA. Within 20km of the International Border specifically, an additional No Objection Certificate from the Ministry of Defence is required on top of MHA clearance.

The Application Process, and Why It's Centralized Through MNRE

Every application, regardless of zone, must be submitted exclusively to MNRE. State governments and project proponents are explicitly barred from applying directly to MHA or the Ministry of Defence. MNRE forwards the proposal, along with the state government's in-principle land allotment approval and the project's precise latitude and longitude, to MHA for security clearance and to Defence for the NOC where required.

MHA aims to dispose of applications within 60 days "as far as possible," language that signals a target, not a guaranteed statutory timeline. Projects that already held MHA security clearance or a Defence Ministry NOC before these guidelines were issued are grandfathered in and don't need to reapply.

Structural and Operational Restrictions Beyond the Zone Rules

The guidelines go well past where a project can be sited. Civil infrastructure height is capped, 3 metres for structures between 1km and 8km from the border, rising in tiers to a maximum of 15 metres further out in the 50km belt. Accommodation and hotel facilities for project staff must be located at least 5km from the border; cafeterias must stay within plant premises; and any facility that could attract crowds is barred outright in areas where security is harder to maintain.

Labour restrictions apply too. Engineers, staff, employees, and labour from countries sharing a land border with India, Pakistan, Bangladesh, and China are named specifically, cannot be engaged for project implementation without prior central government approval. Comprehensive security arrangements, including anti-drone systems, are mandatory in sensitive areas, and project designs must include roads wide enough for BSF and armed forces use during emergencies. Land cannot be transferred to a foreign company without prior central approval, and foreign investment in these projects separately requires DPIIT clearance under existing FDI policy.

One Thing Worth Knowing Honestly: This Isn't Applied in a Vacuum

Reporting from The Guardian, cited in coverage of India's renewable sector, has documented that Adani Group has been constructing solar and wind infrastructure within roughly 1km of the Pakistan border in the Rann of Kutch, on land leased by the Gujarat state government, at what is now the Khavda renewable energy park, over 538 square kilometres, targeting 30GW of capacity by 2029, with TotalEnergies holding a 20% stake. According to that reporting, an earlier defence protocol had barred major construction within 10km of the border in that area, and Gujarat officials reportedly lobbied at the highest levels, including a direct approach to the Prime Minister's Office, for that protocol to be relaxed specifically to make the site available.

This is worth an EPC knowing plainly, not as commentary on any party's intent, but because it shows this isn't a purely new or untested restriction being applied to a blank slate. Major infrastructure already exists inside the zone this rule now formally governs, and the framework's actual administration in practice, how quickly and consistently the 60-day clearance target is met for a smaller developer versus a large, established one, is something worth watching rather than assuming will be uniform.

What EPC Teams Should Do Now

Common Mistakes to Avoid

• Assuming a site "near" the border but technically outside 1km has no real restriction, it still falls under the 50km clearance requirement.
• Applying directly to MHA or the Defence Ministry instead of routing through MNRE, this will not be accepted under the current process.
• Treating the 60-day clearance target as a guaranteed timeline when quoting a project schedule to a client.
• Overlooking the structural rules, height caps, accommodation setbacks, road-width requirements, treating this as purely a siting question rather than a full project-design constraint.
• Assuming an existing project's grandfathered status without confirming it actually predates the guidelines' issuance.

Where Reslink Fits In This Conversation

A border-zone project isn't just a design and financing question anymore, it's a compliance timeline question with real, binding milestones (MNRE submission, MHA clearance, Defence NOC where applicable) that need to sit inside the same project plan as construction and interconnection. Reslink's proposal workflow lets EPCs attach exact site coordinates and zone status to a project from the design stage, so the actual clearance path, not just the generation estimate, is part of what a client sees.

Frequently Asked Questions

Q1. What exactly is banned within 1km of India's borders?

Any new solar, wind, or hybrid renewable energy project. The Ministry of Home Affairs has designated this a "restricted area" where no project activity is permitted at all, not a clearance process, an outright prohibition.

Q2. What if my project is just outside the 1km line, say at 3km or 10km?

It's not banned, but it falls within the 50km "sensitive area" and requires case-by-case security clearance from MHA. If it's also within 20km of the International Border specifically, a separate Defence Ministry NOC is required as well.

Q3. Where do I actually submit an application for a border-area project?

Only to MNRE. State governments and project proponents are explicitly barred from applying directly to MHA or the Ministry of Defence. MNRE forwards the application, with the state's in-principle land approval and exact coordinates, to both ministries.

Q4. How long does security clearance actually take?

MHA has stated it aims to dispose of applications within 60 days "as far as possible." That's a target, not a guaranteed statutory deadline, and should be budgeted as such in any client-facing project timeline.

Q5. Does an existing project need to reapply under these new guidelines?

No, if it already received MHA security clearance or a Defence Ministry NOC before the guidelines were issued. That status should be documented and verifiable, not assumed.

Q6. Are there restrictions beyond just where the project can be located?

Yes. Civil infrastructure height is capped (3 metres from 1-8km, rising to a maximum of 15 metres further out), accommodation must sit at least 5km from the border, anti-drone security systems are mandatory, and labour from Pakistan, Bangladesh, or China cannot be engaged without prior central government approval.
