How to Make Affordable Housing Solar Work | Resonant Energy #375

A 100 kW rooftop can be a meaningful source of energy savings—and a difficult project to finance. How do you make solar work for affordable housing, churches, and nonprofits? In this episode of the Clean Power Hour, Tim Montague sits down with Ben Underwood and Isaac Baker, founders of Massachusetts-based Resonant Energy, to discuss how they built a solar development business around nonprofits, houses of worship, and low-income multifamily housing. Ben and Isaac explain how a portfolio approach brings buying power and financing to smaller projects, why their business pivoted toward affordable housing, and what developers and installation partners can learn from that model. In the interview, Ben puts completed projects at roughly 5 MW, with about 15 MW in the pipeline. Behind those numbers is years of work aligning customer demand, installation partners, capital, and policy. A central question: do the savings actually reach residents? The conversation distinguishes direct utility-bill benefits from savings that support building operations and improvements, and explores the Connecticut approach described by Isaac. They also discuss changing federal incentives, battery deployment barriers, and the potential of peak-demand compensation. In this episode, you'll hear about: • Why Resonant Energy shifted from anaerobic digestion into community solar and small commercial projects • How the company used community networks to bring solar to churches, nonprofits, and other organizations that struggled to access conventional project finance • Why bundling smaller solar projects into portfolios can make them more attractive to investors • How Resonant Energy moved into affordable multifamily housing after COVID disrupted its faith-based customer base • The role of Massachusetts' net metering and SMART incentive programs in making low-income solar projects viable • How the Inflation Reduction Act helped accelerate Resonant Energy's growth • How solar is becoming increasingly important for all-electric affordable housing developments as electricity costs rise • What a typical 40-unit multifamily solar project looks like, including 75 to 150 kW behind-the-meter systems • How Connecticut's affordable housing solar policy creates a direct benefit for residents • The challenges of deploying batteries on small commercial properties, from local fire codes to federal sourcing requirements • Why rate design and peak-demand compensation matter as federal solar incentives change • Why urban and suburban rooftops and parking canopies could play a much larger role in America's future energy system For developers, EPCs, and affordable housing owners, the takeaway is practical: smaller projects can become a meaningful market when financing, delivery, and resident benefits are designed together.

TVA’s Grid Is Under Pressure. Solar, Storage and Microgrids Could Be the Answer #374

Rising electricity demand and prolonged outages are pushing the Tennessee Valley to rethink how it builds and operates the grid. Where do solar, batteries, and community-scale microgrids fit? In episode 374 of the Clean Power Hour, Tim Montague welcomes Gil Hough, Executive Director of the Tennessee Solar Energy Industries Association (TenneSEIA), for a conversation following the organization’s 2026 conference. Gil explains how the Tennessee Valley Authority (TVA) shapes this distinctive public-power market—and why municipal utilities and electric cooperatives are becoming a source of innovation in solar, storage, and distributed energy. Tim and Gil discuss: • How TVA’s federal public-power structure shapes opportunities for solar and storage developers • Why TVA’s new Integrated Resource Plan includes a distributed-energy strategy alongside utility-scale solar, storage, and other generation • How annual requests for proposals are changing TVA’s approach to large-scale solar and storage procurement • What the invitation-only Resource Solicitation Cluster means for project selection and interconnection studies • How generation flexibility gives local power companies room to develop solar, storage, and virtual power plants • What recent storm outages reveal about the need for local resilience and community-scale microgrids • How TVA’s decision-making and funding model differs from the investor-owned utility model • How TenneSEIA’s committees and utility relationships help developers, manufacturers, and local power companies collaborate For developers and energy professionals, the conversation highlights two routes into the market: TVA’s utility-scale procurement process and partnerships with local power companies pursuing distributed resources. Gil argues that solar, storage, and better load management can help utilities use their infrastructure more effectively and mitigate cost pressures. Tim explores his vision of a grid of community-scale microgrids, with substations serving as hubs for nearby generation and storage. Listen for a practical look at how procurement, utility partnerships, economics, and resilience are shaping the next phase of clean energy in the Tennessee Valley.

Why Batteries Are the Key Technology Behind the Next Energy Economy with Simon Engelke #373

A battery only earns its keep when it can connect to the grid and get to work. What does it take to turn better battery technology into a viable energy project? In episode 373 of the Clean Power Hour, Tim Montague speaks with Dr. Simon Engelke, founder of Battery Associates and Battery MBA and host of the Battery Insiders podcast. They explore the technology, economics, and expertise needed to scale storage across the grid, transportation, and emerging industries. Drawing on his Cambridge PhD in lithium-ion batteries and his work advising and training industry professionals, Simon explains why chemistry is only part of the story. Utilization, manufacturing scale, maintenance, investor confidence, and grid access all shape whether a battery project succeeds. Tim and Simon discuss: • Stationary storage and mobility: where Simon sees demand growing and how vehicle-to-grid programs can put parked EV batteries to work • Battery technology explained: LFP and NMC cathodes, silicon anodes, sodium-ion batteries, and what changes when the electrolyte becomes solid • Manufacturing scale: why increasing production can drive battery costs down through learning and process improvements • Vanadium flow batteries: Tim raises G&W Electric's experience, while Simon discusses pump and seal failures he has encountered and the challenge of proving a bankable business case • Project economics: why cycling, utilization, operating reliability, and a track record matter to developers and investors • Interconnection bottlenecks: Simon describes investors in Germany ready to deploy batteries that cannot yet connect, leaving assets idle while they continue to age • U.S. manufacturing: Simon's view that repurposing automotive battery factories could temporarily expand stationary storage supply, with EV demand changing that equation • New applications: how data centers, drones, humanoid robots, and electric aviation are expanding the conversation beyond solar and EVs • Battery careers: why engineers, solar professionals, business leaders, and people from other disciplines need to understand the full battery value chain • Inside Battery MBA: a 12-week online program built around live industry experts, office hours, and collaborative case studies, with group enrollment options for employers Simon also shares a Battery MBA case study exploring how a data center battery could serve both as backup power and as storage for an island grid. His message to professionals: start with the skills you enjoy using, then look for where they can contribute to the battery industry. For solar, storage, and microgrid professionals, this conversation connects battery innovation with the practical decisions behind project deployment, workforce development, and long-term business strategy.

The Battery Boom Is Moving Beyond EVs

Grid storage is growing faster than the industry expected. EVs accounted for more than 70% of global battery deployment in 2025, down from almost 80% in 2024, according to the IEA. On this CPH Live, Tim Montague and John Weaver unpack stationary battery storage growth and follow the batteries to two places: 230 GW of data center interconnection requests and a solar plus storage copper mine in Congo. They also cover China clean tech investment, EV charging costs, and agrivoltaics. These stories show where new batteries are going and why. Episode Highlights: Stationary storage is taking a larger share of global battery deployment. EVs fell to more than 70% in 2025, down from almost 80% in 2024 (IEA), as EV growth ran slower than projected and grid storage grew faster. Tim opened with a 95% EV figure, John corrected it with the IEA data live, and the hosts named CATL, BYD, and Illinois' new grid law as drivers of grid-scale battery storage. Cross Boundary Energy's Kamoa Copper project in the Democratic Republic of Congo pairs 233 MW of east-west solar with a 526 MWh battery and 30 MW of output. John calls the roughly 8 to 1 DC to AC ratio the largest he has seen. ( Crossboundary Energy ) Tim reports 230 GW of data center interconnection applications across the U.S., against a grid running near 500 GW. He argues 20 million Powerwall 3 units, or one in five homes, would match that load. The hosts discuss grid edge computing from Lektra and Base Power's 40 kWh home batteries, which entered Illinois through the state's virtual power plant legislation. China's share of global clean manufacturing investment fell from 71% in early 2023 to 33% in Q2 2026 ( Reuters ). Tim asked why this counts as good news for solar. Maize under the panels produced 19.6% more dry matter than an open control plot during a drought and heat wave. The panels cut evapotranspiration by 20% ( PV Magazine ). A Sydney green roof ran 28 degrees Celsius cooler, and its solar outperformed a metal roof array by 11% ( Renew Economy ). This episode serves battery storage professionals, solar developers, clean energy investors, and policy watchers. Data center load, gas price spikes, and shifting battery demand all affect project economics right now. Tim and John give you the numbers and more.

Inside a 365 kW Commercial Solar Project: First Solar Series 7 + Custom Racking #372

How do you take a 365 kW commercial solar project from a customer conversation to steel in the ground? In this episode of the Clean Power Hour, Tim Montague goes behind the scenes of a 365 kW commercial solar project for Griffin Beverage in West Branch, Michigan, with Jordan Rhyne of Countryside Energy and Kyle Sinclair of Sinclair Designs & Engineering. The project brought together domestic-content solar modules, custom racking engineering, structural analysis, field installation lessons, and a challenging interconnection process with Consumers Energy. Jordan and Kyle walk through what it took to make the project work, including why the customer wanted a truly domestic solar system, how First Solar Series 7 modules changed the racking design, and what the team learned from taking the system from engineering drawings into the field. In this episode, you’ll learn: • How Countryside Energy identified Griffin Beverage as a strong commercial solar customer • Why the customer prioritized a truly domestically sourced solar array • How First Solar Series 7 modules created unique racking and engineering challenges • Why the racking team developed a purpose-built bracket and clip connection • How structural analysis and FEA helped validate the module-to-racking connection • What installers need to consider when working with frameless thin-film modules • Lessons from module handling, breakage, installation speed, and field tolerances • What EPCs should know before taking on their first First Solar Series 7 project The 365 kW system was designed to offset 110% of the facility's load, the maximum allowed by Consumers Energy for the project. The team also had to coordinate an upgrade of the site's service transformer from 250 kVA to 500 kVA before the system could be energized.

This Startup Pays You to Run AI on Your Solar Power #371

What if your solar system could earn far more by powering AI compute than by selling electricity back to the grid? In this episode of Clean Power Hour, Tim Montague talks with Karl Andersen, founder and CEO of Lektra, about a different approach to the growing power demands of AI. Lektra places GPU servers alongside distributed energy resources such as solar and batteries, turning homes, businesses, and other energy sites into small-scale data centers. Instead of exporting excess solar to the grid, an energy host can use that electricity to power GPU workloads and earn revenue from the compute generated. Karl says Lektra typically gives energy hosts 80% of the resulting revenue while retaining 20% for providing the compute marketplace and infrastructure. The conversation explores why rapidly growing AI demand is exposing limitations in today's electric grid, and whether distributed energy, microgrids, batteries, and edge computing could form part of a more decentralized Grid 2.0. In this episode, Tim and Karl discuss: • Why AI is creating a new market for distributed energy • How Lektra turns solar and other energy assets into edge-scale data centers • The economics of selling compute instead of electricity • How Lektra's 80/20 revenue-sharing model works • Why edge computing could benefit autonomous vehicles, robotics, logistics, and physical AI • How distributed compute could help address data-center grid constraints • Lektra's approach to data sovereignty and on-premises AI • What a more decentralized energy system could look like over the next several decades The future of AI will require enormous amounts of energy. This conversation explores whether some of that demand can be met where energy is already being generated, and whether compute can provide the economic incentive to build a more distributed and resilient energy system.

The U.S. Needs 230 GW of New Power. Where Will It Come From? #370

America may need more than 230 GW of new power capacity through 2030. Regulated utilities are expected to deliver only about 93 GW. So where does the rest come from? Tim Montague takes that question to Sylvia Leyva Martinez, Director of North America Utility-Scale Solar at Wood Mackenzie, on a crossover with her show Interchange Recharged. They work the gap from opposite ends of the industry: utility-scale generation versus C&I, community solar, storage, and microgrids. They cover safe harbor strategy under the ITC phase-out, how projects get financed, and how the AI data center boom reshapes demand. Tim makes his case that distributed energy deploys faster than the interconnection queue allows, and lands on his thesis that the future grid is a grid of microgrids. Tim and Sylvia work the gap between what the U.S. needs and what utilities will build: Where does utility scale end and distributed generation begin? How does the ITC phase-out drive the safe harbor rush? Why do most C&I projects skip PPAs for commercial loans? What does the 230 versus 93 gigawatt gap mean for developers? Which states give community solar its strongest footing? Why does Tim believe the future is a grid of microgrids?

Solar, Vanadium Flow and a Flywheel: Inside G&W's Microgrid #369

G&W Electric's vanadium flow + flywheel microgrid matched a full year of frequency regulation revenue in under three months Vanadium flow batteries rarely anchor a commercial microgrid, but G&W Electric built one around a solar, battery, and flywheel system at its Bolingbrook, Illinois headquarters. John Gounaris, VP of Global Marketing, and John Pederson, Principal Staff Engineer and the project's manager, walk Tim Montague through the build. G&W Electric manufactures switches, reclosers, and grid automation gear used across US utility grids, and its 121-year-old campus needed resilient power to protect production. The project runs on Intelligent Generation's earn, save, protect framework: earn through frequency regulation, save on capacity charges, protect with backup power. Tim presses the guests on capex, opex, and why they skipped lithium-ion. The conversation covers real storm performance in 2026, revenue swings, and how domestic vanadium sourcing shaped the battery choice. Gounaris and Pederson explain the choices behind one of the few flywheel microgrids in operation: Why did G&W skip lithium-ion for a vanadium flow battery? How does a flywheel hold full building load for 62 seconds? What earned G&W more in 10 weeks than all last year? How much of an industrial bill do capacity charges reach? Which US source supplied the vanadium, and why does it matter? How did the microgrid perform during the 2026 Chicago storms?
