Beyond AI infrastructure, India’s tech boom rests on the efficient use of power and water

Distributed solar means generating electricity on many rooftops, close to the homes and buildings using it. Unlike a large power plant, it spreads generation across local sites instead of sending electricity over long distances. This matters because transmission and distribution can add substantially to the price consumers pay.

SolarSquare is a concrete example: it installs rooftop systems for individual households and housing societies. The company has powered more than 60,000 homes and serves around 500 housing societies. Producing power near its users can reduce the distance electricity travels, helping lower the gap between generation costs and final prices.

When SolarSquare entered the market, household adoption was limited, and upfront costs discouraged many buyers. One lakh Indian homes adopted residential solar over five years; today, the country adds that many weekly. Rooftop solar is becoming mainstream, but companies must still prove reliability, maintenance value, and promised output.

India’s rooftop-solar market is accelerating from niche adoption, while wastewater reuse is building around industrial demand. Both markets matter because growing cities and industries need reliable power and water. Solar can generate power near homes, reducing long-distance delivery costs. Treated wastewater can replace freshwater in factories and data centres.

The speed of solar adoption is striking. When SolarSquare began, India needed five years to reach one lakh residential solar homes. Today, the country adds roughly that many homes in a single week. SolarSquare has powered more than 60,000 homes and serves about 500 housing societies.

Wastewater reuse is smaller and slower, constrained by pricing, policy, and public trust. Boson Whitewater repurposed around 147 crore litres over four years for industrial uses. Bengaluru illustrates the challenge: consumers pay about Rs 7 per kilolitre, while supply costs government roughly Rs 95. Growth will depend on proving reliability, improving economics, and winning acceptance.

These industries depend on uninterrupted power because computers, machines, pumps, and cooling systems must keep operating. They also need substantial water for cooling towers and processes such as semiconductor manufacturing, electroplating, and laundry. Reliable supplies prevent costly interruptions as cities and digital infrastructure expand.

Data centres are a clear example: their servers generate heat, so cooling systems need dependable electricity and water. Semiconductor plants similarly use water during manufacturing, while industries compete with cities for limited freshwater. Treated wastewater can serve industrial needs, reducing pressure on groundwater and other freshwater sources.

The scale is already visible. Boson Whitewater says it repurposed around 147 crore litres over four years. SolarSquare argues distributed solar can provide cheaper power closer to users, reducing transmission costs. Yet pricing complicates adoption: Bengaluru consumers pay about Rs 7 per kilolitre, while government supply costs roughly Rs 95. Future growth therefore requires efficient reuse, fairer economics, and trusted infrastructure.

Generating electricity close to homes reduces the distance power travels. That can lower transmission and distribution costs, helping ease pressure on the wider grid. Reusing treated wastewater similarly replaces some freshwater demand for industrial uses.

SolarSquare says distributed solar can become India’s cheapest power source. It has already powered more than 60,000 homes and serves about 500 housing societies. Boson Whitewater has repurposed wastewater for industrial needs, including cooling and manufacturing. This keeps treated water in use instead of sending it down drains or drawing more groundwater.

Over four years, Boson repurposed around 147 crore litres that otherwise would have gone down the drain. Yet pricing remains difficult: Bengaluru consumers pay about Rs 7 per kilolitre, while supply costs roughly Rs 95. These examples show that scaling requires trusted services, fair pricing, and policies that make reuse commercially viable.

Rooftop solar can lower electricity costs, but households must pay much of the bill before seeing savings. They also worry that panels or other equipment may fail, require expensive maintenance, or produce less power than promised. These risks make future savings feel uncertain, especially when consumers do not understand the technology.

When SolarSquare entered India’s residential market, adoption was limited and many families hesitated over the upfront investment. A household must trust the company’s equipment, installation, and performance claims before committing substantial money. Even good long-term economics may not overcome doubts about repairs, reliability, or recovering the initial cost.

That is why consumer trust matters alongside price. SolarSquare says more than 60,000 homes now use its systems and serves about 500 housing societies. India once took five years to reach one lakh adopters, but now adds that many homes weekly. Clear guarantees, dependable service, and transparent savings remain important for wider adoption.

Recycled water must compete with freshwater on price, not just availability. When governments charge users far less than delivery costs, treatment companies struggle to offer an attractive alternative. The subsidy hides freshwater’s true cost and weakens the financial case for reuse.

Bengaluru’s Cauvery supply shows the gap clearly. Consumers pay about Rs 7 per kilolitre, while the government spends roughly Rs 95 bringing water from a distant river. A provider must match that subsidised price, even if reuse saves freshwater. It can also reduce pressure on distant sources.

That pricing structure makes scale difficult, especially because treated water also faces public distrust. Boson Whitewater repurposed around 147 crore litres in four years, yet initially spent two-and-a-half years addressing acceptance. The practical path is targeting industries, including data centres, where large water needs may justify recycled supply.

The price people pay for electricity or water reflects more than production. Transport and treatment can make delivered resources far costlier than their basic production price. Subsidies may also hide these costs from consumers. The same principle applies when water must be pumped, cleaned, or carried to users.

Bengaluru consumers pay about Rs 7 per kilolitre for Cauvery water. The government spends about Rs 95 to bring it from a distant river. That gap shows how transport and subsidised pricing can make freshwater appear cheaper than alternatives, including recycled water.

SolarSquare argues that rooftop generation can reduce long-distance transmission and distribution costs by producing electricity near homes. SolarSquare has powered more than 60,000 homes, while Boson Whitewater repurposed about 147 crore litres in four years. These figures show why scaling depends on trust, workable prices, reliable delivery, and infrastructure, not technology alone.
