Maharashtra's data centre ambitions face power infrastructure bottlenecks

On 25 October, Prime Minister Narendra Modi inaugurated the Reserve Bank of India’s new Data Centre and Cybersecurity Training Institute in Bhubaneswar, Odisha, underscoring the growing importance of safeguarding India’s increasingly digital financial system. Days later, the State Bank of India disclosed a cyber incident that exposed nearly 3,900 customer records.

Against this backdrop of India’s accelerating digital transformation, Maharashtra’s plans to establish Navi Mumbai as a major data-centre hub assume particular significance. Maharashtra has tied up more than 85,000 MW of power, but a 4,000-5,000 MW data centre demand surge, a stalled request for 25 acres for critical transmission infrastructure and mounting coal-supply concerns expose the distance between capacity on paper and reliable electricity on the ground.

The state faces a fundamental challenge: ensuring that the electricity and transmission infrastructure required to sustain this expansion are ready when the projects come on stream. Maharashtra’s ambitious push to establish Navi Mumbai as a major data centre hub is running into a problem that could undermine the investments the state is seeking to attract: the electricity may be tied up, but the infrastructure needed to deliver it is not yet in place.

Chief Minister Devendra Fadnavis has emphatically stated that solar energy will be the preferred choice to electrify data centres in the state. About 15 data centres are under development in the Navi Mumbai region, according to the state’s Energy Department. Their combined connectivity requirement is estimated at 4,000-5,000 MW, of which only about 1,500-2,000 MW has been sanctioned so far. The balance remains a substantial commitment that the state will have to meet as the projects progress.

The scale of the demand is striking. The Energy Department’s assessment is that the electricity requirement of these data centres, including further expansion, could be equivalent to roughly twice Mumbai’s present demand. That prospect places an extraordinary burden on the transmission network serving one of India’s most important financial and commercial centres.

Yet, the immediate obstacle is not simply the availability of electricity. It is the ability to move power to where it will be needed. A proposed 765-kV substation and associated transmission infrastructure are critical to meeting the requirement. The problem, according to Maharashtra’s Energy Department officials, is the availability of land in and around Navi Mumbai. The department has repeatedly sought 25 acres from the Maharashtra Industrial Development Corporation (MIDC) to establish the infrastructure through a special-purpose vehicle (SPV).

Four formal communications seeking the land have reportedly gone unanswered for about a year-and-a-half. Yet another formal missive was issued a fortnight back, an energy department official told Business India on 27 October. This delay raises an uncomfortable question for a state pursuing large technology investments: how can Maharashtra commit to accommodating power-intensive data centres if the agencies responsible for enabling their electricity supply cannot resolve the land requirement for essential infrastructure? “It’s just as if the left hand does not care about what the right hand is doing,” a state secretariat official laments.

A demand surge

Maharashtra’s power-sector expansion has been substantial, which the grid has not been able to accommodate. The quantum of electricity tied up or commissioned has risen from about 37,000 MW to more than 85,000 MW, says Abha Shukla, Additional Chief Secretary (Energy), government of Maharashtra. But generation capacity and the ability to deliver electricity are not interchangeable.

Electricity must be injected into the system, transmitted through the network and delivered to the locations where demand arises. Without adequate transmission capacity, additional power on paper does not necessarily translate into a reliable supply at the consumer’s end.

The pressure is particularly acute in the Pune-Nashik belt and the Mumbai region, where industrial, commercial and residential demand continues to grow. Navi Mumbai’s proposed data centre cluster adds another layer of demand, one that differs from conventional industrial consumption in both scale and the need for dependable supply.

Shukla has indicated that the state has already received connectivity requirements of 4,000-5,000 MW from the data-centre projects, with 1,500-2,000 MW sanctioned. The remaining demand cannot simply be dismissed or indefinitely deferred. As projects move from construction to commissioning, the state will have to ensure that the corresponding electricity infrastructure is ready.

The demand is also staggered. Individual centres will come on stream at different times, with requirements depending on their size and storage capacity. That provides some time for infrastructure development, but not an excuse for administrative inaction. The transmission system must be planned well ahead of the point at which the centres require full power.

The 765-kV substation is central to that planning. Such infrastructure is not built overnight. The process could take three to five years, making the timely identification and allocation of land especially important, contends Shukla.

The private sector is expected to play a role in financing or developing the transmission infrastructure. But private investment cannot overcome the absence of land that must be made available through the relevant public authorities – read the MIDC.

This is where the data centre story moves beyond investment announcements and memoranda of understanding. The test is whether the state’s administrative machinery can deliver the enabling infrastructure on schedule.

The missing 25 acres

The Energy Department’s request to MIDC is not for an incidental facility. It concerns land required for the transmission infrastructure needed to serve the data centre cluster being set up by the latter.

According to a well-placed Energy Department official at Mantralaya, the department has sent four formal communications seeking 25 acres over about 18 months. The absence of a formal response has become a source of concern within the department, which must plan for demand that is already emerging. And now, one more missive sent a fortnight back on the same subject is also awaiting a reply.

The proposed allocation would enable the development of a 765-kV substation and associated infrastructure through an SPV. The underlying argument is straightforward: if Navi Mumbai is being positioned to accommodate a growing number of data centres, the land needed to supply them with electricity must be treated as part of the same development plan.

The Energy Department’s position is that there is little value in facilitating data centre projects without simultaneously making provision for the power infrastructure on which they will be dependent. The state cannot expect electricity connections to materialise simply because projects have been announced or land has been allotted for buildings.

The issue also raises questions about coordination between departments. MIDC is an important instrument of Maharashtra’s industrial-development policy, while the Energy Department is responsible for ensuring that the electricity system can meet demand. When the requirements of these two arms of government intersect, the absence of a timely decision can hold up an investment chain far larger than the land parcel in question.

Business India made repeated efforts to reach P. Anbalagan, Principal Secretary, government of Maharashtra, including visits to his office, SMS messages and voicemail messages on his mobile phone. These attempts did not elicit a response.

According to a senior official at the state secretariat, the four formal communications from the Energy Department seeking 25 acres had remained unanswered since Anbalagan’s tenure at MIDC and continued to be pending after he moved to his present post as principal secretary.

The official said the department had sought the allocation to establish the SPV required to service the unusually high electricity demand expected from Navi Mumbai’s data centres. The department’s argument was that, rather than continue expanding data-centre allocations without making corresponding provision for power infrastructure, the authorities should also allocate land for the additional centres being planned.

“There have only been informal and oral half responses to our efforts,” the senior official told Business India. The distinction between an informal assurance and a formal decision matters. A project of this scale requires clarity on land, timelines, approvals and responsibility. Oral exchanges cannot substitute for an allocation that enables construction to begin.

Nor is the concern confined to the proposed substation. It goes to the credibility of the state’s investment strategy. Data centres require large capital outlays, specialised facilities and a dependable power supply and lakhs of litres of water. Investors must be able to plan commissioning schedules around infrastructure that will actually be available, not merely promised. If the land issue remains unresolved, Maharashtra risks creating a mismatch between the pace at which it welcomes new projects and the speed at which it provides the infrastructure needed to support them.

The legal and regulatory test

The expansion also brings a wider set of regulatory responsibilities into focus. Land allocation and electricity connectivity are only part of the approval process for large data centres. Construction permissions, environmental clearances, open-access arrangements, renewable-energy options and data-protection obligations must also be addressed.

“From a legal standpoint, the key question is how these data centres will be approved and whether the necessary infrastructure can support them,” said Sonam Chandwani, Managing Partner, KS Legal & Associates. “The government will have to ensure that land and construction permissions, environmental clearances and electricity connections are secured through the appropriate authorities. Since data centres require uninterrupted power, the arrangements for electricity supply, open access and renewable energy will be important. Data protection laws will also govern how personal information is handled and secured. If implemented properly, these projects could attract major investments, generate employment and strengthen Maharashtra’s position as a technology hub. However, the government must ensure that this growth does not come at the cost of local resources and infrastructure.”

The point is particularly relevant because the electricity requirement is not a secondary consideration for data centres. Reliable power is fundamental to their operation. A shortfall in the supporting network can therefore become a constraint on the commercial viability and commissioning of the facilities themselves.

The policy challenge is to align the various permissions and infrastructure decisions rather than allow them to proceed in isolation. Land for a data centre, land for a substation, transmission planning and the availability of generation must be considered together.

Maharashtra has an opportunity to establish itself as a major digital-infrastructure destination that leverages progressive compulsions of exploiting among other new age technologies – Artificial Intelligence. But that ambition will depend on the government’s ability to coordinate the agencies responsible for delivering the physical systems that make the investment possible.

The other side of the paradox

The data centre bottleneck is unfolding against a second concern: the reliability of coal supplies to thermal power stations. Maharashtra is worried that coal-supply constraints could adversely affect 10,000-12,000 MW of thermal generation unless supplies are streamlined. This is a reported risk to generation capacity, not a claim that the entire quantum has already been lost. Nevertheless, the potential exposure is significant for a state that must meet growing demand from industry, households and power-intensive digital infrastructure.

The concern has a wider dimension. Gujarat has reportedly approached Maharashtra to understand how it has been able to maintain disruption-free thermal generation amid the difficulties being experienced in coal supply. The enquiry points to a problem that may extend beyond Maharashtra and raises questions about the adequacy of coal-supply and transportation arrangements as electricity consumption increases.

Coal-fired generation remains central to India’s electricity system. A disruption in fuel availability or the logistics required to move it can therefore have consequences beyond the state in which the immediate shortage is reported.

Maharashtra’s concern is that coal supplies are not keeping pace reliably with the requirements of thermal generation. As electricity production and consumption increase, coal supply and transportation must rise correspondingly. If the system cannot deliver fuel when and where it is required, generating capacity becomes vulnerable even when the power station itself is operational.

The Union Coal Secretary needs to clarify the reasons behind the reported disruptions. Are the constraints arising from production, allocation, transportation, railway availability or some combination of these factors? Without a clear explanation, state utilities and generating companies are left to plan around uncertainty.

This is not a marginal issue. If 10,000-12,000 MW of thermal generation is potentially exposed, the consequences for supply planning could be substantial. Maharashtra cannot afford to treat coal logistics as an issue separate from its broader electricity strategy.

The data centre challenge and the coal concern are connected by a common requirement: the electricity system must deliver reliable power when demand materialises. New transmission infrastructure cannot compensate for a shortage of fuel at generating stations, just as additional generation cannot solve a bottleneck in the network that carries electricity to consumers.

The payment question

Coal-supply concerns have also prompted questions about whether payment delays are contributing to the problem. A senior Finance Department official at the state secretariat, however, categorically denied that Maharashtra has pending payments for coal. “We have no pendency of payments towards coal that is outstanding from Maharashtra's side,” the official said. “This much is clear. No demand for coal payments from the Energy Department to our department is pending either”.

The denial is significant. It means that the reported supply concerns cannot simply be attributed to unpaid coal bills on the strength of the information available from the Finance Department. The distinction between a payment problem and a supply or logistics problem must be maintained unless evidence establishes a direct link.

The official’s statement does not, by itself, explain where the coal-supply chain is encountering difficulties. Nor does it settle questions about production, allocations, railway movement or the availability of supplies at individual generating stations.

A senior state government official says, “When the Union Coal ministry was approached in this regard, the monsoons and inadequacy of railway rakes were unconvincingly put forward as the apparent reasons why coal stocks were in short supply. Ironically, coal supply had increased in India and yet Maharashtra experiences coal criticality with only three to four days of requirements in stock as witnessed over the last several weeks.”

That is why a clear account from the Union Coal Ministry is necessary. If Maharashtra’s payments are not pending, the reasons for any supply disruption need to be identified elsewhere in the chain and addressed accordingly.

The issue also demands a coordinated response between the state’s Energy Department, its Finance Department, generating companies, coal suppliers and the agencies responsible for transportation. The reliability of thermal generation depends on the chain functioning as a whole.

The agricultural burden

Maharashtra’s power-sector difficulties are compounded by the financial burden of agricultural electricity dues, which have risen to about Rs1 lakh crore, according to the Energy Secretary. The figure is a measure of the scale of the challenge facing the state’s electricity finances. Agricultural power is politically sensitive, and the provision of subsidised or free electricity has long been a feature of the sector. But unpaid dues cannot be treated as an accounting detail when the system must simultaneously finance infrastructure, maintain generation and expand transmission capacity.

The agricultural arrears must be distinguished from coal-payment liabilities. The Finance Department official has denied pending coal payments, while the Rs1 lakh crore figure relates to outstanding agricultural electricity dues. They are separate issues and should not be conflated.

Nevertheless, the agricultural burden forms part of the wider financial environment in which Maharashtra must manage its electricity system. The state needs to reconcile its social commitments with the requirement to keep utilities financially capable of maintaining and expanding the network.

The demand for power is not standing still. Industrial and commercial consumers require dependable supply, data centres are preparing to enter service, and existing consumers must continue to be served. Meeting those requirements calls for investment in generation and transmission, as well as a sustainable financial framework. The more the sector’s finances are strained, the greater the pressure on the state to ensure that public commitments, subsidies, collections and infrastructure spending are managed coherently.

Capacity-delivery mismatch

Maharashtra’s power-sector paradox is that it has expanded the quantum of energy tied up or commissioned from about 37,000 MW to more than 85,000 MW, yet still faces serious questions about delivering electricity to rapidly growing demand centres and securing reliable fuel for thermal generation. Add to this the fact that its transmission lines are more than three decades old and in urgent need of modernisation.

The data centre story brings that paradox into sharp focus. Navi Mumbai’s projects have created a connectivity demand estimated at 4,000-5,000 MW. While 1,500-2,000 MW has been sanctioned, the state must still prepare for the balance as the projects advance. A 765-kV substation is critical to meeting that demand, and the infrastructure could take three to five years to develop. Yet, the 25-acre land request needed to advance the project has reportedly remained without a formal response despite four letters over approximately 18 months.

The immediate question is not whether Maharashtra can announce more data centres. It is whether the government can co-ordinate land allocation, approvals, transmission planning and power supply quickly enough to support them.

The coal issue adds another layer of uncertainty. A reported exposure of 10,000-12,000 MW of thermal generation requires a clear explanation of the supply constraints and a credible plan to address them. The Finance Department’s denial of pending coal-payment dues makes it all the more important that the authorities identify the actual source of the reported disruption rather than allow speculation to fill the gap.

The Rs1 lakh crore in agricultural electricity dues underlines the financial challenge confronting the sector as demand and infrastructure requirements rise. Maharashtra has the opportunity to turn Navi Mumbai into a major data centre destination. But investment announcements are only the beginning. The state must now demonstrate that its administrative machinery can deliver the land, transmission infrastructure and reliable power on which these projects depend.

A state can invite data centres, sign investment agreements and tie up electricity. The real test is whether the grid – and the government machinery behind it – will be ready when the switch is turned on.
