Gridvik read — two-thirds of this campus is still to be built
A 150 MW headline on a campus with 50 MW live is not a misrepresentation — it is a five-building design at 40% completion. But the distinction decides how a vendor plans: 100 MW of funded, permitted, in-construction capacity is the largest single live build opportunity in Navi Mumbai outside NTT and Sify.
The 48-versus-50 MW discrepancy on the live buildings appears in PDG's own materials across two dates. Gridvik uses 50 MW, consistent with the operator's current facility page, and notes the 48 MW figure.
The delivery record is worth knowing: the first building took about 20 months, through the pandemic, on a site that already had a substation next door. That is the fastest credible build time in the Mumbai market and it is not an accident.
3Power — the decisive advantage
Almost everything that makes this campus commercially strong comes down to one thing: it was sited next to a substation.
The location
MU1 sits directly beside the Kalwa substation. That is a circumstance of site selection, not engineering, and it is the hardest advantage in Indian data centres to replicate
Site substation
A dedicated 220 kV GIS substation on the campus. Gas-insulated switchgear at 220 kV is the top end of Indian data-centre power infrastructure — most facilities connect at 110 kV or 33 kV
Why 220 kV matters
Connecting at a higher voltage reduces losses, reduces the number of transformation stages, and — most importantly — increases the size of load the state transmission utility will sanction. A 150 MW campus needs that headroom; a 110 kV connection supports materially less
What it changes in the equipment list
GIS switchgear at 220 kV, power transformers, protection and control systems, and the associated civil works are a separate and much larger package than a 110 kV installation. This is the single largest electrical contract on the site
Comparison
NTT's Noida 2 publishes no substation rating. Sify's Rabale runs 110 kV for Towers 1–3 and 220 kV GIS for Towers 4–6. Microsoft publishes nothing. On substation disclosure and specification, PDG and Sify lead the Indian market
Renewables
The expanded campus is contracted to be powered 50% by renewable energy
Why this matters to a vendor
A 220 kV connection means the HV package is live, large and specialist. Vendors who only sell at LV/MV distribution level are not in that conversation
4Certifications and design
OCP Ready
India's first Open Compute Project Ready facility. OCP is a hyperscaler-driven open hardware standard for racks, power shelves and server designs. OCP Ready status means the facility can accept OCP-format equipment without modification — a meaningful qualification for hyperscale tenants that specify OCP hardware
IGBC Platinum
Mumbai's first IGBC Platinum-certified data centre
Uptime Tier III
Design and construction certification — concurrently maintainable, meaning any component of the power or cooling path can be taken offline for maintenance without dropping the IT load
Cooling
PDG describes the design as accommodating high rack density requirements and hybrid cooling needs. Hybrid cooling implies provision for both chilled water and liquid cooling in the same building — the current design answer to tenants who cannot yet say how much of their estate will be GPU-based
Renewable target
50% of campus power contracted as renewable on completion
Management systems
ISO 9001, 14001, 27001, 20000, 45001, 22301 and the 27017/27018 cloud-security extensions — the fullest published certification stack of any Indian campus in this registry
What is not published
Rack count, rack density, PUE, chiller architecture, UPS topology, generator configuration and fuel autonomy. The certifications are public; the engineering numbers are not
5The green financing
What a green loan actually requires
In July 2025 PDG secured about US$160 million in green loans for MU1, from Axis Bank, Kotak Mahindra Bank and Canara Bank — bringing PDG's cumulative green loan commitments across Asia to US$728 million.
A green loan is not a marketing label. It requires the borrower to commit to defined environmental performance criteria — typically certification, energy efficiency and renewable procurement — and to report against them. That has three consequences worth understanding.
Consequence 1 — the specification is constrained
Once a facility is financed against green criteria, equipment choices that worsen measured performance become difficult to justify. Expect the cooling and electrical plant to be selected partly on efficiency, not only on price. For a vendor, an efficiency claim is worth more here than a price reduction
Consequence 2 — the lenders are Indian
Axis, Kotak and Canara are domestic banks, not development finance. This is significant: it means Indian bank credit is now available at scale for data-centre build-out, which removes what was historically the binding constraint on Indian operators
Consequence 3 — the paper trail exists
Green-loan reporting creates a documented, filed record of facility performance. Over time this will be the best source of verified PUE and energy data for Indian data centres, better than anything the operators publish voluntarily
The programme it sits in
The US$160 million supports the US$1 billion India programme announced in late 2024, which covered the MU1 expansion to 150 MW and the 72 MW CH1 campus in Chennai
What is not disclosed
The loan margin, the specific green criteria, the reporting cadence, and whether the interest rate steps down if targets are met
6Timeline
The first MU1 building is delivered — in about 20 months, through the pandemic.
PDG announces a US$1 billion India programme: MU1 expands from two to five buildings, taking the campus to 150 MW across about 15 acres, and PDG enters Chennai with a 72 MW campus. First phase of the 100 MW expansion scheduled for 2026.
PDG acquires 500 MW of powered land across Mumbai, Chennai, Johor and Jakarta, occupying over 88 acres — the land bank behind the later 210 MW acquisition.
The second MU1 building goes live, taking the campus to about 50 MW.
About US$160 million of green loans secured for MU1 from Axis Bank, Kotak Mahindra Bank and Canara Bank, bringing PDG's cumulative green loan commitments to US$728 million.
PDG becomes the first in Asia-Pacific to reach OCP Ready v2 hyperscale status; MU1 is described as providing 150 MW of IT capacity across five buildings on a dedicated 220 kV GIS substation.
PDG announces a further 210 MW acquisition in Mumbai and Hyderabad, taking its India operating and planned capacity to about 1 GW — see PRJ-025.

7Procurement
Read this before the table
Two of five buildings are live. Three are funded, permitted and under construction. This is the most actionable large build in Mumbai. Everything below is a Gridvik estimate.
Procurement window and scope
Gridvik assessment · 22 Oct 2026
Order window
Now through 2027. The 100 MW expansion was scheduled to begin delivering in 2026, which means major equipment orders were placed in 2025–2026 and fit-out runs into 2027. The electrical package — driven by the 220 kV GIS substation — is the largest element.
Procurement heat
High. Green-loan-funded, part of a US$1 billion India programme, with a hyperscale tenant profile and a demonstrated fast-build capability.
Who buys
PDG centrally, with group engineering standards applied through the India team. PDG is a specialist hyperscale developer rather than an incumbent Indian operator, which in practice means a smaller and more accessible vendor panel
DG / gensets (indicative)
At 150 MW IT with N+1 redundancy, roughly 190–220 gensets of 2,000–2,250 kVA class across the campus. The 100 MW expansion alone implies about 130–150 units. Mumbai requires CPCB IV+ compliance
UPS (indicative)
Tier III concurrently maintainable implies at minimum N+1 on UPS; hyperscale single-tenant floors increasingly use distributed battery at the rack, which reduces centralised UPS content per MW
Cooling (indicative)
Hybrid by design. PDG publishes hybrid cooling capability, which means both chilled-water CRAH plant and liquid-cooling provision exist in the same buildings. For a vendor this is the ideal case: one order, two cooling categories, and a green-loan requirement that rewards efficiency over purchase price
Categories in scope
220 kV GIS switchgear · power transformers · protection and control · DG and gensets · UPS and rack-level battery · PDUs and busway · chillers, CRAH and dry coolers · CDUs and liquid cooling · high-density racks and containment · structured cabling and fibre · fire detection and suppression · BMS/DCIM · fuel storage · water treatment · renewable PPAs
