LG Energy Solution plans to bring over 50 gigawatt hours of annual battery manufacturing capacity online in the US by the end of 2026 across five facilities (MI, IL, AZ, OH, GA). The company also projects a 15% cost reduction on its next-generation cells by 2028. Tim Montague and John Weaver dig into that story and more in this May 1, 2026, edition of Clean Power Hour Live.

Tim and John cover five stories this week, drawn from industry publications and their own active projects in the field.

• LG Energy Solutions is building five battery factories with a combined capacity of 50+ GWh per year, targeting completion by the end of 2026. The company projects a 15% cell cost reduction by 2028. (Energy Storage News)
• Tandem PV began demonstration manufacturing of a perovskite-silicon module reaching 29.7% efficiency, backed by a warranty of less than 1% annual degradation over 25 years. (Solar Power World)
• On April 27, Trina Solar claimed the world record for silicon solar cell efficiency at 28%. Longi broke that record the very next day. (PV Magazine)
• The US Department of Commerce announced preliminary anti-dumping duties of 123% on solar modules from India, 35% from Indonesia, and 22% from Laos. (PV Magazine)
• Republican lawmakers introduced new legislation to extend the commercial solar ITC, which currently expires at the end of 2027. Safe-harboring by July 4, 2026, extends project runway to July 3, 2030. (Solar Power World)

The battery capacity numbers, perovskite efficiency milestones, and tariff developments covered here carry direct implications for procurement and project planning decisions in 2026 and beyond.

San Diego pays the second-highest electricity rates in the United States, trailing only Hawaii, and peak-hour pricing from 4 pm to 9 pm runs up to triple morning rates. In this episode, Tim Montague sits down with Rod Matthews, President of Brevian Energy, a North County San Diego developer focused on solar, battery storage, and community microgrids. Brevian works with Community Choice Aggregators to deliver behind-the-meter solar and storage at no upfront cost to commercial property owners. Tim and Rod cover the Clean Energy Alliance Solar Plus Battery program, a 25-year power purchase agreement with a 1% annual escalator and lease payments to the host site.

Here's what you'll learn in this conversation about California microgrids and community solar:

• You'll learn how the Clean Energy Alliance Solar Plus Battery program gives commercial property owners with 15,000 square feet of rooftop or 25 carport spaces a 25-year power purchase agreement at a 1% annual escalator with no upfront cost. Property owners also receive lease payments escalating at 2% per year, outpacing energy cost increases.
• Learn about how California's 4 pm to 9 pm peak window changes the math on storage. Rates during those hours run up to triple morning rates, so dispatching from the battery during peak makes projects pencil out in SDG&E territory, the second most expensive utility market in the US behind Hawaii.
• Understand how a closed landfill in Chollas View, San Diego, will host 10 megawatts of solar and 40 megawatt hours of lithium iron phosphate storage to serve 25,000 homes with at least 20% utility bill savings. Local residents become co-owners through a Special Purpose Vehicle for as little as $100 per share.
• Learn why community buy-in determines whether brownfield and microgrid projects move forward.

Energy prices are climbing as data center demand grows and natural gas prices spike on global tensions. California's duck curve makes evening storage the limiting factor for further solar adoption. This episode shows a working model for solving both problems at commercial scale and at the community level.

Eighty-five towns across New York state sit under battery storage moratoriums right now, and two of three Westchester County towns where Joe Tassone Jr. built successful battery projects in 2020 have since banned the technology outright. In this episode, Tim Montague sits down with Joe Tassone Jr., partner at onCORE Origination, a site origination firm working in 25 states on solar, battery storage, data centers, and EV infrastructure.

This episode covers the top three issues blocking battery development at the community level, why fire safety fears around lithium-ion storage miss the wider context, and what separates developers who close projects from those who waste millions.

Here's what you'll learn in this conversation about battery development and site origination:

• You'll hear the three biggest objections communities raise against battery storage projects.
• Find out why 85 New York towns currently sit under battery moratoriums, and how two of three Westchester County towns where Joe built projects in 2020 have since banned storage outright.
• Learn why Joe argues developers should never treat zoning as black and white, even in towns with outright bans, because public utility statutes and use variances open paths to approval through the judicial process.
• Understand how state-level programs in Illinois, Maryland, and Connecticut remove local NIMBY obstacles.
• You'll get Joe's three tenets of successful development: knowing where to go through parcel acumen, committing fully to a market with a clear pipeline vision, and persisting relentlessly through headwinds.

Joe's 30 years of site origination experience surfaces one clear lesson: developers who treat zoning as static codes and give up at the first denial lose tens of millions in project value every year. The industry needs to move from reactive to proactive, meeting with town and county associations before moratoriums pass instead of reacting after.
