Datacenters are the heart of the digital economy and the demand for datacenters is expected to rise substantially, positioning them as a primary focus for growth and investment. But the cost of operating datacenters is also rising substantially due to rising electricity prices and increased datacenter consumption. A new International Data Corporation (IDC) report looks at datacenter electricity spending and the implications for technology providers and datacenter operators.

A new IDC report looks at datacenter electricity consumption and spending and the implications for technology providers and datacenter operators.
Electricity is by far the largest ongoing expense for datacenter operators, accounting for 46% of total spending for enterprise datacenters and 60% for service provider datacenters. And electricity consumption is growing rapidly as datacenters take on more workloads and more energy-intensive workloads, such as artificial intelligence.
IDC expects the surging demand for AI workloads will lead to a significant increase in datacenter capacity, energy consumption, and carbon emissions, with AI datacenter capacity projected to have a compound annual growth rate (CAGR) of 40.5% through 2027. Accordingly, AI datacenter energy consumption is forecast to grow at a CAGR of 44.7%, reaching 146.2 Terawatt hours (TWh) by 2027 with AI workloads consuming a growing portion of total datacenter electricity use.
Overall, IDC expects global datacenter electricity consumption to more than double between 2023 and 2028 with a five-year CAGR of 19.5% and reaching 857 Terawatt hours (TWh) in 2028.
At the same time, electricity prices are rising due to supply and demand dynamics, environmental regulations, geopolitical events, and sensitivity to extreme weather events fueled in part by climate change. IDC believes the trends that have caused electricity prices to increase over the last five years are likely to continue. Rising consumption and increased energy costs will make datacenters considerably more expensive to operate, but how much is uncertain.
To better understand the impact of rising electricity costs on datacenter operations, IDC conducted scenario planning for a datacenter with 1 MW of IT load in 2023, running at 50% capacity and power usage effectiveness (PUE) of 1.5. The study looked at three energy price growth scenarios using energy pricing and growth rates for the United States, Germany, and Japan. In all three scenarios, the percentage growth in electricity spend exceeds a CAGR of 15% in all cases, with most scenarios showing growth of over 20%. The study also shows that an additional 10% in energy efficiency can offer considerable savings to datacenter operators.
“There are any number of options to increase datacenter efficiency, ranging from technological solutions like improved chip efficiency and liquid cooling to rethinking datacenter design and power distribution methods,” said Sean Graham, research director, Cloud to Edge Datacenter Trends at IDC. “But providing energy-efficient solutions is only part of the equation for meeting customer needs. Datacenter providers, including cloud and colocation services, should continue to prioritize investment in renewable energy sources. By investing in renewables, they are helping to increase overall supply while helping their customers meet their sustainability goals.”

Solar and wind power, in particular, offer significant environmental advantages while also providing the lowest levelized cost of electricity (LCOE), which reflects the average net present cost of electricity generation over a generator’s lifetime. And by collocating facilities at or near the source of renewable energy generation, providers can reduce both construction costs and energy losses associated with distribution, enhancing overall efficiency and sustainability while also improving resiliency by removing grid reliability issues.
The IDC Market Perspective report, The Financial Impact of Increased Consumption and Rising Electricity Rates in Datacenter Facilities Spending (Doc #US52548324), provides an overview of the growing demand for datacenters, the energy requirements to run these facilities, and the rising cost of electricity to datacenter operators. Recommendations to improve datacenter energy efficiency are offered for both technology providers and datacenter operators.
The IDC report, AI Datacenter Capacity, Energy Consumption, and Carbon Emission Projections (Doc #US52131624), examines how the AI-driven surge in the datacenter market will impact AI datacenter capacity, energy consumption, and carbon emissions. The report highlights the challenges of power shortages, shifting toward energy-efficient and carbon-free operations, and adopting microgrids and renewable energy sources.
