In this episode of Catalyst, host Shayle Kann is joined by Andy Lubarshain, partner and head of research at Energy Impact Partners, to unpack whether data centers are actually causing electricity prices to rise. They argue that the answer depends entirely on whether you look at the question locally or globally. At the local level, data centers generally have a neutral to slightly deflationary effect on consumer electricity bills because utilities are negotiating strict tariffs where the massive load addition expands the denominator in rate calculations. Conversely, at the global and macroeconomic level, the sudden surge in power demand acts as a demand shock that strains supply chains for transformers, gas turbines, and conductors, driving up infrastructure and maintenance costs across the board. The conversation explores the public backlash against data centers, the role of energy efficiency and load flexibility, and potential novel tariff models to secure community buy-in.
Shail Khan opens the episode, introduces the topic of data center impact on electricity prices, and mentions a recent article by Andy Lubrashain.
A brief ad segment highlights GridBeyond’s flexible energy management solutions for data centers.
Andy re-enters the conversation to discuss his recent piece on data center electricity price effects.
Andy explains the distinction between local utility effects and global market effects of data centers on electricity prices.
Andy outlines how the rapid data center boom creates a global demand shock, driving up supply‑chain costs for the entire power system.
Shail and Andy discuss possible mitigation strategies, future studies, and the need for more data on local and global impacts.
Local Versus Global Perspectivesinsight
The guest explains that the impact of data centers on electricity prices tells two very different stories depending on whether you examine it at a local or global level.
The Basic Utility Rate Formulastrategy
The guest details how regulated utility rates are determined by dividing the aggregate cost to serve by the total kilowatt-hours sold.
Negotiating Fair Share Tariffsstrategy
Utilities and data center developers are successfully negotiating tariffs that ensure data center customers pay more than their fair share, preventing rate hikes for local residents.
EPRI Study on Data Center Ratesdata
A recent study by EPRI found that data centers have actually had a mild, beneficial impact on consumer bills, lowering them by roughly 6% on average.
Two-Thirds of Utility Spend is Maintenancedata
According to data from the Edison Electric Institute, two-thirds of all utility spending in the United States goes toward basic maintenance and grid hardening rather than growth.
Supply Chain Inflation Across Componentsdata
Key electrical grid components like conductors, switchgear, and gas power plants have become significantly more expensive, doubling or tripling in cost.
Energy Cost Share for AI Data Centersdata
Energy typically accounts for a relatively small share of 5% to 10% of total operating costs for an artificial intelligence data center.
“The question is essentially whether data centers are causing electricity prices to rise, to which Andy's answer was essentially no and also yes.”
“In reality, what we're seeing today, of course, is that in most utility service territories, it's not the case that there's a lot of headroom left on the grid.”
“And when you do control for other variables that might bias the analysis, EPRI found that basically, on average, data centers are lowering customer bills a little bit already.”
You don’t have to look far to see the vitriol and backlash ignited by the rapid expansion of hyperscaler data centers. While critics and activists tend to focus their ire on resource consumption and residents’ electricity bills, the reality of data center economics is far more complex. In this episode of Catalyst, host Shayle Kann sits down with Andy Lubershane, head of research at Energy Impact Partners, to unpack the nuances. They crunch the numbers behind utility rate structures, consider the "denominator effect" that can lower customers’ rates, and dig into the supply chain crunches pushing global power system costs higher. Shayle and Andy discuss: - Why a new data center can reduce utility rates for locals while contributing to rising costs elsewhere - How data centers impact utility tariff rates - Separating public perception of data centers from the reality of the grid - How soaring demand for transformers, switchgear, conductors, gas turbines, and labor is driving systemic cost increases across the power sector - Strategies to mitigate rising global grid costs, from load flexibility and distributed energy resources (DERs) to energy efficiency hardware - Catalyst: What comes after the data center backlash? - Catalyst: Enter the electric supercycle - Catalyst: Can AI revolutionize grid operations? - Catalyst: Inside the AI power wars - Open Circuit: As midterms approach, electricity bills are on the ballot - Open Circuit: Data centers have a Texas-sized energy problem - Latitude Media: The great home battery financing experiment Credits: Hosted by Shayle Kann.
