Why This Matters Now

Explosive OTT growth and the data‑center bottleneck

India’s over‑the‑top (OTT) ecosystem is in the midst of a historic surge. According to a recent CNBC report titled “Inside India newsletter: Asia’s hottest data center market aims to quell concerns over water and power use” (published 22 Oct 2026), the country added 2.3 GW of data‑center capacity in FY 2025‑26—more than any other Asian market in the same period. The driver is unmistakable: OTT subscriptions have risen from 380 million in 2023 to an estimated 460 million in early 2026, with Gen‑Z and millennials accounting for 62 % of monthly active viewers.

The revenue implication is equally stark. Combined OTT revenue is projected to cross ₹150 billion (≈ $1.8 bn) in FY 2026, a 28 % YoY increase, while average bitrate per stream has climbed from 2.5 Mbps to 4.2 Mbps as 4K and HDR content become mainstream. Higher bitrate translates directly into greater compute and storage demand, which in turn spikes electricity consumption and cooling requirements.

Power grid strain and water scarcity

India’s power grid, already operating at 85 % of its peak load during summer months, faces a looming shortfall of roughly 15 GW by 2027, according to the Ministry of Power. Simultaneously, the country’s freshwater withdrawal for industrial cooling has risen 12 % annually, with data‑center cooling accounting for an estimated 0.3 % of total national water use—a figure that may sound modest but is critical in water‑stress zones like Maharashtra and Karnataka.

The convergence of these pressures has pushed regulators, investors, and ESG rating agencies to demand concrete OTT data center sustainability measures. The Securities and Exchange Board of India (SEBI) now requires listed OTT firms to disclose carbon‑intensity and water‑use metrics in quarterly filings, while global investors such as Temasek and BlackRock are conditioning fresh capital on verifiable sustainability roadmaps.

Regulatory and market incentives

In response, the Indian government announced a “Green Data‑Center” incentive scheme in March 2026, offering a 20 % tax rebate on capital expenditures for projects that achieve a Power Usage Effectiveness (PUE) of ≤ 1.3 and incorporate water‑recycling technologies. State utilities in Maharashtra and Telangana have also introduced time‑of‑use tariffs that reward data‑center operators for shifting non‑critical workloads to off‑peak hours, creating a financial lever for AI‑driven demand response.

Collectively, these forces make the OTT data center sustainability narrative not just an environmental imperative but a competitive differentiator. Platforms that can guarantee uninterrupted streaming while keeping their carbon footprint below 0.5 kg CO₂e per hour of HD playback are poised to win both consumer trust and investor confidence.

• Renewable mix: As of Q3 2026, 38 % of OTT data‑center power in India comes from renewable sources, up from 22 % in 2024, thanks to long‑term power purchase agreements (PPAs) with solar farms in Rajasthan and wind farms in Tamil Nadu.

• PUE trends: Industry‑wide average PUE has improved from 1.55 in 2022 to 1.38 in 2026, yet the most efficient facilities—those employing liquid immersion—report PUE as low as 1.12.

3. Water‑intensive cooling challenges

Traditional air‑side cooling relies on large volumes of chilled water, drawing from municipal supplies. In Mumbai’s monsoon‑affected districts, water tariffs have risen to ₹15 per 1,000 liters, prompting operators to quantify water cost as a material expense. Moreover, the Ministry of Environment’s 2025 guidelines set a ceiling of 0.5 liters of water per kWh of IT load for new data‑center projects, tightening compliance pressure.

4. Five sustainability strategies adopted in 2026

#### (a) Liquid‑submerged (immersion) cooling

Leading the pack, Amazon Web Services (AWS) India launched its first immersion‑cooled zone in Hyderabad, submerging servers in a non‑conductive dielectric fluid. This method reduces water use by up to 85 % and cuts energy spent on fans by 40 %. Early‑stage data shows a 30 % reduction in overall PUE for the zone.

#### (b) On‑site solar‑plus‑storage micro‑grids

Netflix India partnered with Tata Power Solar to install a 50 MW solar farm adjacent to its Bengaluru data‑center campus, coupled with a 200 MWh lithium‑ion battery array. The micro‑grid supplies 70 % of the site’s daytime load, shaving ~ ₹12 crore (≈ $1.5 mn) in electricity bills annually and providing a buffer during grid outages.

#### (c) Waste‑heat recovery for district heating

SonyLIV’s Mumbai data‑center now channels waste heat to a nearby commercial complex, providing hot water for a 15‑storey office building. The initiative recovers roughly 2.8 MW of thermal energy, translating into an estimated 5 % reduction in the building’s natural‑gas consumption.

#### (d) Rainwater harvesting and gray‑water recycling

Disney+ Hotstar’s Hyderabad hub installed a 3‑million‑litre rainwater harvesting system, supplemented by a gray‑water loop that treats condensate from air‑conditioning units. The combined system supplies 90 % of the cooling‑tower make‑up water, cutting municipal water procurement costs by ₹6 crore per year.

#### (e) AI‑optimised workload shifting & demand response

All major OTTs have integrated AI platforms that predict peak streaming windows and dynamically migrate non‑critical batch jobs (e.g., transcoding) to off‑peak periods. By aligning compute intensity with lower‑tariff electricity windows, operators achieve an average 12 % reduction in energy cost and contribute to grid stability, a metric now tracked in ESG disclosures.

5. Financial implications for OTT operators

• CapEx vs. OpEx: While immersion cooling and solar‑plus‑storage require upfront investments of ₹8‑12 billion per site, the projected 5‑year payback—driven by lower water tariffs and reduced electricity bills—makes the net present value (NPV) positive at a 7 % discount rate.

• Investor sentiment: ESG‑focused funds have re‑allocated roughly ₹45 billion into Indian OTTs that meet the “green data‑center” criteria, a 22 % premium over peers lacking such disclosures.

• Consumer perception: A June 2026 survey by Kantar IMRB found that 68 % of Indian streaming users consider a platform’s sustainability practices when choosing a subscription, especially among Gen‑Z respondents.
