Microsoft Powers AI Ambitions with 400 MW Solar Purchase

Microsoft Expands Renewable Energy Portfolio to Fuel AI Growth

Microsoft has bolstered its renewable energy resources with an additional 389 megawatts of capacity. This expansion is driven by the increasing power requirements associated with the company’s ambitious artificial intelligence initiatives.

New Solar Projects

The newly acquired renewable power originates from three solar projects developed by EDP Renewables North America. Two of these projects are located in southern Illinois, while the third is situated near Austin, Texas.

Microsoft’s strategy involves procuring both electricity for its local facilities and renewable energy credits to offset demand in other regions.

Current Renewable Capacity

According to Microsoft’s 2024 sustainability report, the company currently contracts for nearly 20 gigawatts of renewable energy capacity. This latest acquisition represents approximately a 2% increase to that total.

Rapid Power Procurement

The tech giant is actively securing power supplies at an accelerated rate to support its growing cloud and AI operations. Like many in the industry, Microsoft favors renewable energy sources due to their rapid deployment and cost-effectiveness.

Speed of Solar Deployment

Solar energy, in particular, offers a swift implementation timeline. Compared to the years required for constructing new gas power plants, a solar farm can begin generating electricity in as little as 18 months.

Developers are increasingly planning projects with phased commissioning, enabling them to deliver power to data centers as quickly as possible.

Hybrid Renewable Installations

To ensure a consistent power supply, 24/7, some renewable energy developers are implementing hybrid systems. These systems combine solar and wind power with battery storage.

Batteries are charged during periods of high renewable energy production and discharged when production decreases. Amazon recently entered into an agreement for a similar development in Portugal.

Sustainability and Carbon Negative Goals

Purchasing renewable energy allows Microsoft to operate its core business functions without generating pollution. This also contributes to the company’s commitment to become carbon negative by 2030.

Achieving this goal requires Microsoft to remove and store more carbon from the atmosphere than its operations produce.

Carbon Removal Investments

Beyond renewable energy, Microsoft is investing in various carbon removal technologies. These include direct air capture, enhanced rock weathering, and reforestation efforts.

Last month, a deal was announced with Chestnut Carbon to purchase over 7 million tons of carbon credits. This amount is sufficient to offset roughly half of Microsoft’s 2023 emissions.
