How a 700kW Commercial Solar Project Saves $3M+ Over 25 Years #363

Dual-use solar financing in action: Sunrise Solar's Richard Stoltzfus built a 700 kW behind-the-meter array for Harbor Sales Company. The build stacks a USDA REAP grant with a Maryland MEA grant and drives the customer's levelized energy cost to near zero.A 700 kW behind-the-meter solar array now offsets 70 percent of the electric load at Harbor Sales Company, a plywood and sign-panel distributor that has run out of Sudlersville, Maryland since 1931. Richard Stoltzfus, CEO of Sunrise Solar, and Kendrick Tice, COO of Sunrise Solar, join host Tim Montague to walk through their Chestertown-based company's build for Harbor Sales. Montague and Stoltzfus dig into the mechanics of commercial solar incentives in Maryland, the sunset of the 30 percent federal ITC, and why rural electric cooperatives in the PJM region are capping new solar interconnections even as demand for grid capacity grows.Here is what you will learn in this conversation about dual-use solar and commercial solar incentives:Learn how Sunrise Solar stacked a USDA REAP grant with Maryland's MEA grant to push a customer's levelized cost of energy toward zero on a 700 kW system.Find out how a 700 kW array offsets 70 percent of Harbor Sales Company's load and pencils out to more than 3 million dollars in savings over 25 years.Understand why the 30 percent ITC sunset and Delmarva Power's tightening interconnection limits pushed this project from planning into construction.Hear Kendrick Tice explain why Sunrise Solar sources its racking from one manufacturing partner instead of juggling multiple vendors, and what that does for project timelines.Hear Tim Montague weigh in on whether rural cooperatives in the PJM region can keep pace with rising demand for grid capacity and where incentive structures differ from state to state.Maryland's grant-stacking model, layering a USDA REAP grant on top of a state MEA grant, offers a template for other states as the federal 30 percent ITC winds down. At the same time, rural cooperatives across the PJM footprint are capping new solar interconnections, a constraint Stoltzfus and Tice say is already blocking chicken farmers and dairy operations from going solar. Professionals financing behind-the-meter projects in cooperative territory will find the co-op discussion directly relevant to deals in the pipeline right now.Connect with Guests Richard Stoltzfus | LinkedIn Kendrick Tice | LinkedIn Sunrise Solar | Website  Support the showConnect with Tim  Clean Power Hour  Clean Power Hour on YouTubeTim on TwitterTim on LinkedIn Email tim@cleanpowerhour.com Review Clean Power Hour on Apple PodcastsThe Clean Power Hour is produced by the Clean Power Consulting Group and created by Tim Montague.

Georgia's Data Center Boom Is Straining the Grid. Here's How Solar Fits In #362

Georgia is the second-largest data center market in the country, and its grid is straining under load growth no one predicted five years ago. Michael Chanin, CEO of Cherry Street Energy, joins Tim to break down how behind-the-meter solar and storage are stepping in, why utilities need private capital to keep rates in check, and what a multi-gigawatt data center outside Savannah means for the region. Tim sits down with Michael Chanin, CEO of Cherry Street Energy, a vertically integrated power company based in Georgia that develops, owns, and operates behind-the-meter solar and storage for commercial and industrial customers across the Southeast.Georgia repealed its ban on third-party solar ownership in 2015, opening the door for "Solar Energy Procurement Agreements" (Georgia's version of a PPA). Since then, Cherry Street has built a customer base that includes Delta Air Lines, Porsche Cars North America, Gulfstream, and the City of Atlanta, offering no-cost, no-upfront-investment solar that cuts customers' energy bills and carbon footprint.Chanin and Tim dig into what is driving unprecedented load growth in Georgia: the state is now the second-largest data center market in the US after Virginia, and OpenAI recently announced its "Project Camellia" data center campus near Savannah in Effingham County, a $20 billion, 3.2-gigawatt (3,200 MW) project built in partnership with Georgia Power. On the recording, Chanin describes the project as a joint Anthropic/OpenAI announcement and cites 4,000 megawatts of capacity; public reporting on this specific project ties it to OpenAI at roughly 3,200 MW, so that detail is worth a quick check with Chanin or Cherry Street before publishing. Other topics covered:How Cherry Street's economics pencil out: average customer electricity cost of 10-12 cents/kWh, build costs under $1.50/watt, and how real-time pricing has made solar competitive even against historically cheap fossil generationCherry Street's solar-plus-storage pilot with Georgia Power and the emerging value stack for behind-the-meter batteries (capacity payments, energy payments, demand management)Georgia's Public Service Commission, including Chair Jason Shaw and newly elected Democratic commissioners Alicia Johnson and Peter HubbardCherry Street's vertically integrated delivery model: in-house engineers, general contractors, and site supervisors that take a project from signed contract to energized system in under 100 daysCherry Street Energy shows what happens when a state removes one legal barrier and lets the market do the rest. Georgia's 2015 shift on third-party ownership opened the door. Rising load growth from data centers and electrification is now forcing utilities, regulators, and private developers to work together on a scale nobody planned for a few years ago. Chanin's take is clear: solar and storage are not a side story in Georgia's power future. They are becoming part of how the state keeps the lights on and the bills manageable. Listen to the full conversation for the details on Cherry Street's build process, its storage pilot with Georgia Power, and what EPCs and developers should know before entering the Southeast market.

Why 80% of Grid-Ready Devices Are Still Sitting on the Sidelines? #361

The U.S. needs 400 GW of new capacity over the next two decades. Michael Grasso, CEO and founder of Grid Rails, tells Tim Montague that roughly twice that much flexible capacity is already plugged in, and explains why only 20% of eligible devices are enrolled in virtual power plant programs today.Data centers, EVs, heat pumps, and new construction are pushing U.S. electricity demand up by roughly 50%, about 400 gigawatts over the next two decades. The reflex answer is to build more generation. Michael Grasso thinks we are solving the wrong problem.Grasso is the CEO and founder of Grid Rails, and he spent 17 years getting to that conclusion. He helped deploy the first residential storage batteries at Sunrun, first on LG Chem hardware and then on Tesla, and he ran the largest residential storage virtual power plant in the country at Sunnova, supporting Luma's grid in Puerto Rico. His argument: the flexible capacity sitting inside the devices causing the load growth is close to double the load growth itself. What is missing is the orchestration and settlement layer that turns those EVs, batteries, thermostats, and water heaters into dispatchable grid capacity, and pays the consumer for it in real time instead of months later as a buried bill credit.Thirty-four states now have some form of demand response or VPP program on the books, and by Grasso's numbers, only about 20% of eligible devices are actually enrolled. Tim pushes hard on why, and on whether any of this pencils for a homeowner who does not want one more app sending notifications.What you will learn:Why 80% of eligible devices are still on the sidelines, and why Grasso calls that a program design problem rather than a hardware problemHow real-time settlement changes consumer behavior, and what it unlocks for utilities beyond incentives: collateral, cost of capital, bad debt, and new products like prepaid or unlimited EV chargingWhy Grid Rails is built for the moment a customer opts out, not for constant notifications, and how opt-out recovery keeps programs from quietly bleeding participantsThe ERCOT math driving utility urgency: roughly $50 per MWh bought forward against spot exposure that can run to $5,000What Grasso says a simple VPP application is worth to a household, around $500 a year in most markets and into the thousands in some, and why he thinks a more dynamic market leaves a lot more on the tableWhy per-device budgets matter, from capping EV charging at $15 a week to holding air conditioning to 20% of the billGrasso points to headlines warning that the largest utility in the country is signaling blackout risk as soon as 2027, and treats that as the pressure finally moving utilities toward orchestration. Tim comes at it as a customer, not an analyst: he does not have a battery yet, his own rate just jumped 25%, and he wants a number before he buys. That exchange is the heart of the episode.Connect with Michael Grasso, Grid RailsMichael Grasso | LinkedIn: https://www.linkedin.com/in/michaelpgrasso/Grid Rails: https://gridrails.ai/Email: hello@gridrails.ai Support the showConnect with Tim  Clean Power Hour  Clean Power Hour on YouTubeTim on TwitterTim on LinkedIn Email tim@cleanpowerhour.com Review Clean Power Hour on Apple PodcastsThe Clean Power Hour is produced by the Clean Power Consulting Group and created by Tim Montague.

Wildfire Smoke Cuts New England Solar Output by 40 Percent

Wildfire smoke from Canada cut solar production across New England by as much as 40 percent, according to ISO New England, a loss of 2,500 megawatts at peak hours compared to the forecast. Tim Montague and John Weaver dig into that data, including John's own project numbers, on the Clean Power Hour Live. They also cover a massive BYD battery storage deal in Abu Dhabi, a new gas car ban in China, rising copper prices, and a wave of new battery products hitting the market. Whether you're an installer, developer, investor, or simply following the clean energy transition, this episode covers the trends you need to know.In this episode:BYD secures an 11.275 GWh battery storage contract for one of the world's largest clean energy projects. (BYD Energy press release)Wildfire smoke cuts solar production by up to 40% in parts of New England. (WBUR)China's Hainan province set a 2030 deadline to ban new combustion engine car sales, with plans for new energy vehicles to reach 45 percent of the province's fleet. (Dialogue Earth)Massachusetts expanded its vehicle-to-grid and virtual power plant programs through the ConnectedSolutions initiative (regional VPP program).SEIA data shows utility-scale solar occupies just 0.07% of America's prime farmland. John Weaver corrects the math live, and SEIA's own figures show roughly 43 acres of abandoned prime farmland for every acre solar currently occupies. Tim and John debate the politics behind the farmland argument. (PV Magazine)Octopus Energy launches the Nook Cube smart battery for renters. (Renewable Energy Magazine)Copper prices continue climbing and what that means for future solar project costs. (BlueSky)This episode fits solar developers, battery storage professionals, EPCs, and clean energy investors tracking both hardware innovation and real-world grid risk. The BYD deal and Octopus battery launch show where storage economics are heading, while the wildfire smoke data is a preview of a grid challenge more regions will face.

The Grid Can't Keep Up. Can Linear Generators Solve the Power Crisis? #360

Power generation is changing fast. As utilities struggle with interconnection delays and growing electricity demand, businesses are looking for faster, more reliable ways to secure power.In this episode of Clean Power Hour, Tim Montague sits down with Walt Jordan, Chief Revenue Officer at dGEN Energy Partners, to explore one of the least talked-about emerging technologies in distributed energy: linear generators.Unlike traditional generators, linear generators have no crankshaft, no spark plugs, no engine oil, and very few moving parts. They are designed to operate continuously, and they run on multiple fuel sources, including natural gas, propane, hydrogen, ammonia, and biogas. Combined with solar, battery storage, and microgrids, they may offer commercial and industrial facilities a new path to reliable, behind-the-meter power that can lower their LCOE.The conversation also explores why dGEN  Energy is combining roofing, solar, battery storage, and distributed generation into integrated energy solutions that help businesses reduce costs, improve resilience, and avoid lengthy utility interconnection delays.Whether you work in commercial solar, microgrids, energy storage, EPC development, or distributed energy resources, this episode offers valuable insights into important technology options.In this episode, you'll learn:• What a linear generator is and how it differs from diesel generators• Why dGEN Energy believes linear generators can complement solar and battery storage• How the technology operates without spark plugs, oil, or traditional engine components• The fuels linear generators can use, including hydrogen, propane, natural gas, ammonia, and biogas• How behind-the-meter generation is helping businesses overcome utility interconnection delays and rising energy costs• Why "speed to power" is becoming a competitive advantage• How commercial roofing and solar can be combined into a single engineered capital project• Where batteries, microgrids, and linear generators work together• The emissions profile and efficiency of modern linear generators• Real-world commercial and industrial applications for distributed generation• What EPCs, facility owners, and developers should know before adopting this technologyAs utilities struggle to keep pace with growing electricity demand and interconnection delays continue to slow new projects, businesses are being forced to rethink how they generate and manage power. This conversation with Walt Jordan explores why linear generators are emerging as a compelling option alongside solar, battery storage, and microgrids, especially for commercial and industrial facilities that cannot afford to wait years for grid upgrades.Whether linear generators become a mainstream technology or remain a specialized solution, the bigger story is clear. Speed to power, energy resilience, and flexible distributed generation are becoming just as important as the cost of electricity itself. Connect with Walt Jordan:Walt Jordan | LinkedIn Website: https://dGEN energy.com Support the showConnect with Tim  Clean Power Hour  Clean Power Hour on YouTubeTim on TwitterTim on LinkedIn Email tim@cleanpowerhour.com Review Clean Power Hour on Apple PodcastsThe Clean Power Hour is produced by the Clean Power Consulting Group and created by Tim Montague.

The Grid Was Built Over a Century Ago. Here's How We Fix It. #359

America's electric grid wasn't built for AI, electric vehicles, battery storage, or the rapid growth of renewable energy.So how do we modernize a system that was built and started in the late 1800s and early 1900s, more than a century ago?In this episode of Clean Power Hour, Tim Montague sits down with Zaid Ashai, CEO of Nexamp, the nation's largest community solar developer, to discuss community solar, battery storage, grid modernization, and why policy certainty is essential to building a cleaner, more reliable, and more affordable energy system.Nexamp operates across 19 states and has become one of the leading developers of community solar, distributed generation, utility-scale solar, and battery storage. The conversation centers on the Clean and Reliable Grid Affordability Act, Illinois' new storage law that targets 3,000 megawatts of storage by the end of 2030, with the first procurement round set for August 2026 and two more rounds to follow in 2027 and 2028. Ashai lays out why In this episode, you'll learn:Why America's electric grid needs modernization How community solar benefits homeowners, renters, businesses, and utilities Why the Clean and Reliable Grid Affordability Act uses an indexed storage credit contract instead of a merchant revenue model How storage unlocks additional generation capacity without new transmission and distribution buildout What a Massachusetts ISO study found about grid size when storage is left out of the equation Why Illinois requires 14 percent of a participating project's workforce to be equity eligible How Nexamp's renewable energy fellowship with City Colleges of Chicago grew from 20 students toward a projected 80 by year-end Why affordable clean energy starts with predictable regulation How flexible interconnection and curtailment could unlock more capacity on the existing grid Which states Nexamp is watching next for community solar and storage growth, including Ohio, Michigan, Virginia, Maryland, and PennsylvaniaIf you work in solar, battery storage, utilities, project development, energy policy, grid modernization, or renewable energy investing, this episode offers practical insights into where the industry is headed next.The first Clean and Reliable Grid Affordability Act (CRGA) procurement round opens in August 2026, with two more rounds following in 2027 and 2028, so the pricing structure Ashai describes will shape Illinois storage economics for years. Illinois already holds the only B grade on the Institute for Local Self-Reliance Community Power Scorecard, ahead of New York, Massachusetts, and California, at a moment when federal support for clean energy programs is pulling back. For developers and investors watching how states balance affordability, reliability, and equity, Illinois is currently the clearest test case in the country.About Zaid AshaiZaid Ashai is the CEO of Nexamp, the largest community solar developer in the United States. Under his leadership, Nexamp has expanded into battery storage, utility-scale solar, and integrated clean energy solutions across 19 states.

Lives Saved: The Case for Community Microgrids #358

Community microgrids saved lives during a PG&E shutoff in Humboldt County. Lisa Cohn of Microgrid Knowledge has tracked every project getting built in America right now. She tells you what separates the ones that succeed from the ones that fail, and what you need to know before entering this market.Community microgrids are among the fastest-growing segments in solar and storage, and among the hardest to finance and build. Lisa Cohn is the co-founder of Microgrid Knowledge, a publication she has run for over a decade, covering every major microgrid deployment in the United States. In this episode, Lisa joins host Tim Montague to break down the funding models, utility partnerships, and regulatory frameworks that determine whether a community microgrid gets built or abandoned. The conversation covers California's shift from the restrictive CMEP program to the MIP, the rise of tribal microgrids, public power's structural advantage over investor-owned utilities, and the emerging model of networked microgrids that share power across adjacent communities. If you work in solar, storage, or clean energy development, this episode gives you a clear picture of where the community microgrid market stands today and where the openings are.Here is what you will learn from this conversation about community microgrids:You will hear why Blue Lake Rancheria became the defining case study for community microgrid resilience. When PG&E shut off power across Humboldt County during a wildfire event, Blue Lake's microgrid kept running and saved lives.Find out how the Redwood Coast Airport microgrid got funded. It secured $5 million from the California Energy Commission and $6.5 million in low-interest USDA loans, and Lisa explains why that funding combination is the model worth studying.Learn why California's CMEP program failed and how the MIP replaced it. CMEP gave utilities total control and restricted microgrids to outage-only operation. The MIP removed those restrictions, enabling 24/7 operation, grid services, and demand response.Understand what public power utilities do differently from IOUs when it comes to microgrids. Lisa explains the over-the-fence rule, why tribal land creates exceptions, and why the Portland General Electric model in Beaverton is worth watching.Find out why legislation comes before market growth, not after. Oregon passed two bills specifically for community microgrids in wildfire-prone areas before the market matured, and Lisa explains why that sequencing matters for every other state.State legislation in Oregon is already moving community microgrids forward in wildfire-prone areas, and California's MIP program is enabling Clean Coalition to deploy microgrids that run 24/7 and sell grid services. At the same time, the DOE tribal funding program is producing deployments in states like Wisconsin that would not otherwise have the capital to build. The window for solar and storage professionals to get ahead of this market is open right now.Connect with Lisa Cohn cleanenergywriters.comLisa Cohn | LinkedIn Home | Microgrid Knowledge  Support the showConnect with Tim  Clean Power Hour  Clean Power Hour on YouTubeTim on TwitterTim on LinkedIn Email tim@cleanpowerhour.com Review Clean Power Hour on Apple PodcastsThe Clean Power Hour is produced by the Clean Power Consulting Group and created by Tim Montague.

Carport Solar Done Right: Engineering, Pricing, and Building for the Long Haul #357

Solar carport installation costs can swing by 12 cents per watt before a single panel goes up. Kyle Sinclair, CEO and co-founder of SDE (Sinclair Designs and Engineering), James Strizki, Project Manager and CFO of GenMounts and Renewable Energy Holdings, and Matt Boyce, a PE licensed in 27 states and Principal Engineer at Engineered Solutions, join Tim Montague to break down exactly how carport projects are won and lost. Between them, they have engineered, manufactured, reviewed, and installed hundreds of megawatts of solar structures. This webinar covers the full arc of a carport project from initial bid to commissioning, with a focus on where costs blow up and what to do before you break ground to prevent it.Here is what you will learn in this conversation about solar carport installation and commercial carport project execution:Find out why experienced rooftop EPCs get surprised when they move into carports. Carport structures run 25 feet tall, require serious drilling and concrete work, and the average project size is around half a megawatt, with 100 cubic yards of concrete per site.You will learn how to structure the due diligence process before a single hole is drilled. James Strizki walks through geotech reports, 811-dig calls, web soil GIS software, conversations with local drillers, and a field layout walk a week before mobilization.Understand what ground conditions actually cost you on a carport bid. Kyle Sinclair gives real numbers: $800 per drilled hole in clean Michigan clay versus $2,500 per hole when you hit shale, a difference that adds $60,000 to a half-megawatt project and creates a 12-cent-per-watt cost swing.Find out the three foundation types you will encounter on carport projects and when each one applies. James covers drilled shafts, spread footings, and hybrid helical pile systems, and explains why the wrong choice or a rushed choice can undermine a parking lot within a year or two of commissioning.You will hear Matt Boyce explain why he will not stamp an existing carport structure for solar unless it was originally designed for the load, and what independent structural review actually protects in a project.With residential installers entering the commercial carport market in growing numbers, the gap between what a project looks like on paper and what crews find underground is widening. Kyle Sinclair notes that some EPCs entering this space are used to low-cost, high-volume, cookie-cutter projects and are now bidding work that is the complete opposite, large, expensive, heavily customized, and months in the making. If you are pricing carport work or planning to, the cost variability covered in this conversation is not theoretical.Connect with GuestsKyle Sinclair | LinkedIn James Strizki, P.E. | LinkedIn  Support the showConnect with Tim  Clean Power Hour  Clean Power Hour on YouTubeTim on TwitterTim on LinkedIn Email tim@cleanpowerhour.com Review Clean Power Hour on Apple PodcastsThe Clean Power Hour is produced by the Clean Power Consulting Group and created by Tim Montague.

CATL's Sodium Ion Battery Could Last 30 Years: Rebuild Your Storage Model Now

CATL unveiled its TENER Sodium energy storage system at Intersolar Europe in Munich, rated for 15,000 cycles to 70 percent state of health at room temperature. CATL frames that as a 25 to 30 year service life, and it takes only 34 modules to stand up a one gigawatt-hour site. That single specification changes how commercial storage professionals price, propose, and finance battery projects. Tim Montague and John Weaver dig into what it means, alongside Illinois growing from about 80 megawatts of solar a decade ago to over 6,000 megawatts today under the new CRGA law, SunBallast ballasted racking and what module stacking tells you about install labor, UK bids for 16 and 18 hour long-duration storage, perovskite modules reaching the residential market, El Niño shifting solar output across the US, and silver falling more than 50 percent from its 2026 peak.Episode HighlightsCATL sodium ion battery, 15,000 cycles: CATL launched its TENER Sodium system at Intersolar Europe in Munich. It is rated for 15,000 cycles to 70 percent state of health at 25 degrees C, which CATL frames as a 25 to 30 year service life, and just 34 modules build a 1 GWh site. (Energy Storage News)Sodium ion safety advantage: CATL claims its sodium cells cut expansion force by roughly 40 percent, generate about 35 percent less gas during thermal runaway, and hold peak surface temperatures far below comparable lithium ion. The fire and thermal-runaway story is a big part of why C&I buyers are paying attention to sodium. (Interesting Engineering)Sodium ion in the fast-response role: John flagged a detail from a CATL hybrid storage proposal where sodium was specified for the faster-response duty and lithium for the slower role. Worth keeping in context. This is one proposal's configuration, not a blanket claim that sodium beats lithium on response everywhere.GM and Peak Energy sodium ion partnership: General Motors is moving into stationary storage with Peak Energy, backed by a strategic investment from GM Ventures. GM will develop the sodium ion cell in its Michigan battery lab and keep exclusive manufacturing rights, while Peak integrates the cell into its passively cooled storage systems. Peak energized the first U.S. grid-scale sodium-ion system, 3.5 MWh, in Watkins, Colorado, in 2025. (Inside Climate News)Illinois energy transition, 80 MW to 6 GW: Tim attended a Nexamp event at the company's Chicago office, where IPA director Brian Granahan reported Illinois has grown from about 80 megawatts of solar a decade ago to over 6,000 megawatts energized today, with roughly 14.5 gigawatts of wind and solar developed under the state RPS (13 GW to date plus about 1.5 GW just approved). The engine is CRGA, the Clean and Reliable Grid Affordability Act (SB 25, pronounced "Surge"), which runs its first utility-scale storage procurement in August, the opening tranche toward 3 GW by 2030 via additional 2027 and 2028 rounds. Residential VPP enrollment opens in mid-July, with ComEd and Ameren customers able to put home batteries into a short-term scheduled-dispatch pilot this summer. (PV Magazine)SunBallast racking and install labor: The hosts walk through SunBallast ballasted, no-penetration racking and get into the labor economics of module mounting, including what the way different manufacturers stack modules for shipping tells you about handling time on the job site.UK long-duration storage bids at 16 and 18 hours: Fresh procurement results out of Scotland and England show projects awarded at 16 and 18 hours of duration. John notes it is the first time he has seen bids at that scale and ties it to Scotland's wind-heavy generation profile. (Blue Sky)Trina Solar perovskite module hits residential market: Trina landed its first commercial order for a perovskite-silicon tandem module, going into New Zealand's premium residential market. The record-setting module is 907 watts at 29.2 percent efficiency, certified by TUV SUD. (Perovskite Info)El Niño and solar irradiance shifts: John walks through regional solar output swings across the US and globally. Rajasthan, India, home to some of the world's largest solar plants, is projected to run about 15 percent above its seasonal average this season. (PV Magazine)Silver prices fall more than 50 percent: Silver has dropped from its late-January 2026 record near 121 dollars to the upper 50s, more than half off the peak, on a stronger dollar and a hawkish Fed. It matters for PV because silver paste is a real line item, and World Silver Survey data shows solar's silver demand down about 19 percent. (TheStreet)This episode is essential for commercial solar installers, battery storage developers, community solar professionals, and clean energy policy watchers. The sodium ion story has direct and immediate implications for how professionals structure storage proposals, financial models, and customer conversations. Illinois developers will also want Tim's firsthand account of the CRGA storage procurement and the residential VPP pilot going live this summer.
