Google has tapped Berkshire Hathaway’s NV Energy to source geothermal energy to power its data centers in Nevada, the tech giant said this week.
The deal, pending regulatory approval, is based on Google’s new clean transition rate structure called the Clean Transition Tariff (CTT). Aiming to accelerate the adoption of clean technologies and help companies meet emissions goals, the tariff matches clean energy generation and customer load. It specifically targets more investment in clean firm power such as geothermal, long-duration energy storage and advanced nuclear energy.
“This allows customers to meet their growing electricity demand with 24/7 CFE [carbon-free energy] through their existing utility relationship and share in the long-term benefits that these projects provide, like increasing the share of clean and reliable power,” Google said.

Google Exec: More Collaboration Needed for Clean Power
As part of the first-of-its-kind energy supply agreement, Google, through NV Energy, procured 115 megawatts (MW) of geothermal power from Fervo Energy. The move builds on Google’s pilot geothermal project with Fervo to power the tech company’s Cloud region in Nevada. The pilot’s delivery of carbon-free electricity in 2023 marked a first for Fervo’s enhanced geothermal system. The geothermal company uses proven oil and gas drilling techniques such as hydraulic fracturing and horizontal drilling to capture heat from hot rock to create electricity.
“Now, through our energy supply agreement with NV Energy, we’re expanding by almost 25x the amount of enhanced geothermal capacity enabled by Google, bringing more round-the-clock clean power onto the local grid that serves our data center operations in Nevada,” Google said.
According to Google, the CTT structure can be replicated in other U.S. electricity markets. Google and NV Energy proposed a framework that can be customized for various state regulatory environments to address state and customer goals.
“This innovative proposal will not be paid for by NV Energy’s other customers but will help ensure all our customers benefit from cleaner, greener energy resources,” said NV Energy CEO Doug Cannon. “If approved, it provides a blueprint for other utilities and large customers in Nevada to accelerate clean energy goals. We look forward to progressing this proposal through the regulatory process to approval and look forward to sharing this with other customers to advance the additional economic opportunities it can bring to our state.”
Duke Energy in May announced a similar agreement with Google, Microsoft, Amazon and Nucor to meet growing power needs in North Carolina and South Carolina.

RNG Operator Sevana Bioenergy Acquires Rialto Bioenergy
Sevana Bioenegy, an Idaho-based renewable natural gas developer, has acquired the Rialto Bioenergy Facility located in Rialto, California.
Rialto, a subsidiary of Anaergia, is an organic waste-to-energy facility designed to convert organic waste streams into 1 MMBtu per year of carbon negative RNG and soil products, according to a news release. It has a permitted capacity of 1,000 tons per day of food waste separated from municipal solid wastes and municipal biosolids.
The acquisition came after Rialto initiated voluntary Chapter 11 restructuring proceedings in the U.S. Bankruptcy Court for the Southern District of California in 2023.
“The Rialto Bioenergy Facility is a strategic asset that aligns perfectly with Sevana Bioenergy’s mission to accelerate the production of RNG,” said John McKinney, CEO of Sevana Bioenergy. “This acquisition strengthens our presence on the West Coast and allows us to continue playing a vital role in helping California achieve its ambitious renewable energy and waste diversion goals.”
BP’s Archaea Energy, Republic Services Startup Indiana RNG Facility
BP-owned Archaea Energy and waste disposer Republic Services brought the first of more than 40 landfill renewable natural gas plants online as part of their Lightning Renewables joint venture (JV).
The two companies marked the startup of the Archaea Modular Design (AMD) plant at Republic’s National Serv-All Landfill in Fort Wayne, Indiana, according to news released June 13.
Such projects involve turning methane emitted from decomposing waste at landfills into pipeline-quality gas. The RNG is used similar to fossil gas but with a lower carbon intensity. The fuel source is already playing a role in lowering emissions in the U.S. as the number of RNG projects grows.
Instead of taking the custom build route for RNG plants, BP Archaea utilizes a modular design. Its RNG facilities are built on skids with interchangeable components. The design allows for faster builds than previous industry standards, the company said.
The Fort Wayne RNG facility is designed to process 6,400 cf of landfill gas per minute (scfm) into RNG, according to the release. Based on the U.S. Environmental Protection Agency’s Landfill Gas Energy Benefits Calculator, that’s enough gas to heat more than 25,000 homes annually.
The JV’s planned buildout of RNG plants is expected to be the largest of its kind for landfill RNG in the U.S. It is also expected to lift Republic’s landfill gas-to-energy portfolio to more than 100.
Archaea and Republic Services plan to bring another RNG plant online in Indiana later this year. The 2,000-scfm AMD RNG plant will be located at Republic Services’ Sycamore Ridge Landfill in Pimento, south of Terre Haute, Indiana.

RWE Prepares for Survey Work for Floating Wind Off California
RWE is gearing up to carry out site investigation survey work at its floating wind project offshore northern California, with activities beginning as soon as June 2024.
The Germany-based company on June 12 said it selected subsea services provider Argeo to conduct the surveys in 2024 and 2025 for the Canopy Offshore Wind Farm. Looking for the best spots to install wind turbines, the service company will gather data about the federal lease area as well as the area between the lease and shore in federal waters, RWE said. RWE secured development rights for the area off Humboldt County during a 2022 federal offshore lease auction.
“Due to the water depths in the lease area off the Pacific Coast of the U.S., Argeo will utilize an autonomous underwater vehicle (AUV) to conduct the surveys,” said Dave Gentle, vice president for North and South America at Argeo. “The use of an AUV as the survey platform during this initial site characterization effort will enable high-quality data collection close to the seafloor, including photographs of biological communities.”
RWE has plans for a 1.6-GW wind farm, providing enough electricity to power 640,000 homes. It would be the company’s first commercial-scale floating offshore wind farm.
“Surveying is an important step on the path toward developing Canopy Offshore Wind and helping provide clean energy that meets California’s ambitious climate goals,” said Sam Eaton, CEO of RWE Offshore Wind Holdings. “RWE is committed to responsible, inclusive development by engaging Humboldt residents, Tribal Nations and working closely with the fishing community as we begin offshore activities on the project.”
RWE also selected Geo SubSea and Coastal 35 Consulting to provide protected species observers (PSO) on survey vessels and Smultea Sciences to deliver PSO training to Tribal citizens and the Humboldt County community.
Ørsted to Install Tesla Battery for UK Offshore Wind Farm
Renewable energy group Ørsted will install a Tesla Megapack battery storage system linked to Britain’s Hornsea 3 offshore wind farm, the Danish company said on June 12.
Energy storage is becoming increasingly important as production of renewable energy rises, because the wind might not blow or the sun shine during the peak hours when most consumers turns on their lights and appliances.
“The battery will help ensure that renewable energy is used in the best possible way by storing it when demand is lower and then releasing it back into the system when it’s really needed,” Ørsted’s U.K. and Ireland Chief Duncan Clark said in a statement.
This would help reduce price volatility for consumers by making more power available, including during peak periods when energy is traditionally more expensive, Ørsted said.
The system, set to be operational by 2026, will be co-located with the onshore converter station at Swardeston in eastern England, and will have a capacity of 600 MWh, equivalent to the daily energy usage of 80,000 U.K. homes.
Ørsted did not disclose the size of the battery investment.
