New Report Suggests Household Upgrades Could Offset Energy Demand From Data Centers
Recent analysis released by the non-profit Rewiring America proposes one solution for keeping the burgeoning demand for electricity in check without escalating utility costs further. According to its new report – Homegrown Energy: How Household Upgrades Can Meet 100% of Data Center Demand Growth – the organization makes a case for a rapid investment in heat pumps, rooftop solar, and home batteries in order to change the average home from being a passive energy consumer into “an active energy asset.” Furthermore, the report suggests that following these measures would reduce energy bills for families while strengthening the electric grid.
The report stated that U.S. electricity demand is expected to climb by 128 GW over the next five years, with new AI-driven data centers accounting for 93 GW of that growth. Already homeowners have experiencing extraordinary price hikes by their respective utilities due to increased demand on the existing energy grids. “Utilities requested $29 billion in rate hikes this year alone,” Rewiring America noted.
The new report shows that hyperscalers can unlock the capacity they need – and build a better energy future – by decreasing residential peak demand through direct investment in household upgrades:
• Heat pumps — By paying for heat pumps in select homes that currently rely on inefficient electric heating, cooling, and water heating, hyperscalers could meet one-third of their projected additional capacity needs.
• Rooftop solar + storage — Equipping households with suitable rooftops with solar and storage could generate more than enough clean electricity to meet all projected additional data center capacity needs.
• System transformation — Immediate investments in these solutions would accelerate the technological and economic pathways for an all-electric economy, becoming more efficient, resilient, and affordable for households.
The report finds that hyperscalers could secure grid capacity at costs similar to building new gas power plants by paying for part of the upfront costs of electric upgrades such as the aforementioned installation of rooftop solar plus storage and installing heat pumps in homes with electric resistance heating.
Rewiring America’s research suggests that unlike new gas power plants, heat pumps deliver immediate household benefits such as “an average household bill savings of $740 per year, total annual emissions reductions equal to taking six million cars off the road, and $2.3 billion in total annual health benefits from cleaner air.” The report estimated that with a 50% discount, a heat pump would cost households about $9,000 – which is less than a typical furnace and central AC replacement – making upgrades a clear win for homeowners as well as the power grid. Adding rooftop solar and storage was predicted to potentially lower household energy bills by more than $1,000 per year, while providing more energy resilience to power outages and add resale value to homes.
“Electrifying households is a direct path to meeting the growing power needs of hyperscale data centers while creating a more flexible, resilient, cost-effective grid for all,” said Ari Matusiak, CEO of Rewiring America. “The household doesn’t have to be a passive energy consumer, at the whim of rising costs. Instead, it can be the hero and, with smart investment, the foundation of a more reliable and affordable energy future.”
