Houston startup raises $6M to grow AI platform for solar, battery contractors

fresh funding

Houston tech startup Artemis has raised $6 million from 10 investors. The company offers an AI-supported platform that enables solar, battery storage and home improvement contractors to design, sell and finance energy projects.

Long Journey and Copec WIND Ventures co-led the round, with participation from angel investor Scott Banister, Coalition Operators, FJ Labs, Ludlow Ventures, Palm Tree Crew, Plug and Play Ventures, Shrug Capital and Tribeca Ventures.

To help propel growth, the company secured $10 million in financing last year (under its previous name, Monalee) from venture debt and growth credit provider Applied Real Intelligence. As Monalee, the company raised $16 million in venture capital.

The company was founded in 2022 as an installer of solar and battery storage projects. Five years later, the startup used in-house technology to establish its standalone software platform as it began pivoting away from installation. The company recently adopted the Artemis brand name.

Artemis says its platform saves time and money for installers of residential solar, battery storage, and energy projects. The platform combines an AI-powered design tool with embedded financing capabilities and compliance automation to create a single operating system.

The company says its customers report as much as a 72 percent reduction in software costs and up to 98 percent faster turnaround times. Thus far, more than 100 installers are using Artemis’ technology.

“Installers shouldn’t need six tools and a week of back-and-forth to sell a project," Walid Halty, co-founder and CEO of Artemis, said in a press release. “This funding gives us the fuel to scale our mission to compress design, financing, and compliance into a single flow so every installer can operate like a modern energy company. We’re not just speeding up deals, we're modernizing how distributed energy gets built.”

The Artemis platform, now available in the U.S. and soon to be launched in Latin America, caters to home improvement contractors, solar companies, lenders, and utilities.

“Artemis is transforming the complexity of distributed energy into elegant simplicity," added Arielle Zuckerberg, general partner at Long Journey.

power deal

Houston-based Consolidated Asset Management Services (CAMS) has been selected to operate Plano-based Nexus Renewable Power's major renewables development, known as Project Goody.

CAMS will provide comprehensive asset management, operations, maintenance, regulatory compliance and remote operations services for the $220 million solar and battery storage project located in Lamar County, Texas, northeast of Dallas.

“The project underscores CAMS’ commitment to supporting dependable, grid-strengthening energy infrastructure across the United States,” Brian Ivany, EVP of CAMS Renewables, said in a news release. “Our team is proud to support Nexus and excited to apply our subject matter expertise and hands-on approach to ensure operational excellence and long-term success of the Goody project.”

Project Goody, or MRG Goody Solar and Storage, will feature a 172-megawatt solar facility paired with 237 megawatts of battery energy storage. The project will be connected to the ERCOT grid. Meta, the parent company of Facebook, has signed on as the power offtaker for the project.

Nexus Renewable Power develops, finances and operates solar and energy storage assets. It currently operates projects generating 325 megawatts of solar and 350 megawatts of battery storage, with another 300 megawatts of solar and 1 gigawatt of battery storage projects under construction, according to its website. Project Goody is the first in a series of renewable developments underway, according to Nexus.

CAMS manages and operates energy infrastructure assets for its clients. Last year, it added InfraRed Capital Partners, which owns the 202-megawatt Mesteño Wind Project in the Rio Grande Valley, to its customer list. It also rolled out services to help deliver power to meet the growing demand from AI data centers.

Solar power and storage help save Texans millions on electric bills, CEO tells Senate

price stability

Solar power and battery storage are saving Texans hundreds of millions of dollars on their electric bills, the president and CEO of the Solar Energy Industries Association recently told a congressional committee.

Abigail Ross Hopper, the association’s president and CEO, said in testimony given to the U.S. Senate Environment and Public Works Committee that states like Texas that are adding significant capacity for solar power and battery storage are enjoying lower, more stable prices for electricity.

“Unsubsidized solar is now the cheapest source of electricity in history in much of the country,” Hopper said. “With no fuel costs, solar provides a hedge against natural gas price volatility that continues to cause electricity price spikes.”

“The only way to put downward pressure on prices is by bringing more power online, not less,” she added.

To illustrate the value of solar power and battery storage, Hopper compared two hot summer days in Texas—one in July 2022 and the other in July 2025.

Hopper explained that the Electric Reliability Council of Texas (ERCOT) had begun installing solar on its grid in 2022 but had very little battery storage. ERCOT manages 90 percent of the state’s electrical load.

When ERCOT grid conditions buckled under high demand on the highlighted day in 2022, the price of electricity spiked to nearly $1,500 per megawatt-hour, Hopper said.

“Three years later, the amount of solar had increased substantially and was complemented by energy storage,” she said.

On the specified day in 2025, under even greater demand than three years earlier, sizable amounts of solar power, battery storage and wind power kept ERCOT’s midday price of electricity low and stable—around $50 per megawatt-hour. That dollar amount represented a nearly 100 percent decrease compared with the highlighted day in 2022.

Solar and wind supplied nearly 40 percent of Texas’ power during the first nine months of 2025, according to the U.S. Energy Information Administration (EIA).

Despite the state’s expansion of solar power and battery storage capacity, residential electricity prices in ERCOT’s territory rose 30 percent from 2020 to 2025 and are expected to climb another 29 percent from 2025 to 2030, according to a forecast from the Texas Energy Poverty Research Institute.

The increase in electric bills is tied to factors such as:

  • Higher natural gas prices
  • Greater demand from AI data centers and cryptomining facilities
  • Extreme weather
  • Population growth
  • Development of new transmission and distribution lines

The strain on ERCOT’s grid is only getting worse. An EIA forecast predicts demand for ERCOT electricity will jump 9.6 percent in 2026, and ERCOT expects a 50 percent jump in demand by 2029.

Base Power supplies power to homeowners and the electric grid through a distributed storage network.

“The chance to reinvent our power system comes once in a generation,” Zach Dell, co-founder and CEO of Base Power, said in a news release. “The challenge ahead requires the best engineers and operators to solve it, and we’re scaling the team to make our abundant energy future a reality.”

Zach Dell is the son of Austin billionaire and Houston native Michael Dell, chairman and CEO of Round Rock-based Dell Technologies.

In less than two years, Base Power has developed more than 100 megawatt-hours of battery-enabled storage capacity. One megawatt-hour represents one hour of energy use at a rate of one million watts.

Base Power recently expanded its service to the city of Houston. It already was delivering energy to several other communities in the Houston area. To serve the Houston region, the startup has opened an office in Katy.

The startup also serves the Dallas-Fort Worth and Austin markets. At some point, Base Power plans to launch a nationwide expansion.

To meet current and future demand, Base Power is building its first energy storage and power electronics factory at the former downtown Austin site of the Austin American-Statesman’s printing presses.

“We’re building domestic manufacturing capacity for fixing the grid,” Justin Lopas, co-founder and chief operating officer of Base Power, added in the release. “The only way to add capacity to the grid is [by] physically deploying hardware, and we need to make that here in the U.S. ... This factory in Austin is our first, and we’re already planning for our second.”

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Battery breakthrough

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
