Protecting Our Grid Lines

The second quarter of 2025 delivered the sharpest single jump in battery energy storage prices since Anza’s inception in 2021, exceeding even the industry-wide lift seen between 2021 and 2022 as the industry dealt with post-pandemic supply chain woes. Successive layers of United States tariffs landed within a forty‑day window, and manufacturers reset quotes almost overnight. This report analyzes two common project sizes: a 40 MW distributed‑generation project and a 200 MW utility‑scale project, each configured for four hours of duration. All prices come directly from manufacturers through the Anza platform and include the latest tariffs, shipping, and duties. 

Important notes: 

● All figures are shown on a project CapEx basis for the U.S., covering costs like materials, commissioning, and applicable tariffs. 

● Data runs through May 19, 2025, and reflects the 90 day China tariffpause effective beginning May 14, which temporarily lowers the rate on Chinese battery imports. 

● AC system prices cover the battery block, Power Conversion System (PCS), and Energy Management System (EMS). 

● DC systems cover the battery block only. 

Key Market Factors Affecting Current Energy Storage Prices 

1. TariffShock Drives the Market 

A universal 10 percent tariff, a 145 percent total IEEPA tariffrate on China, and Section 301 pushed every manufacturer to pause quoting in early April. Most returned to the market by late April with shorter validity windows. The May reprieve cuts the IEEPA China rate to 30% for 90 days beginning May 14 (Section 301 remains in effect), but suppliers continue to protect their margin through contract contingency clauses. 

2. Lithium-Carbonate Prices Fall 

Spot lithium‑carbonate indices fell from 77,500 CNY per tonne in February to 64,500 by early May (-17%), reaching their lowest level since 2021. The savings on cell cost could not offset the tariffshock, so delivered system prices still rose. 

3. Shipping Costs Increase 

Asia-U.S. container production rose sharply due to the tighter vessel supply caused by tariffs. The 90-day tariffreprieve that went into effect on May 14 is expected to increase shipping costs in Q3 2025 as all industries try to bring imports into the US to take advantage of the lower tariffs. 

4. Preliminary Anode-Material Ruling Under Review 

The International Trade Commission released a preliminary countervailing‑duty decision on Chinese active anode material on May 20, 2025. The base duty of 6.55% may have minimal impact at the DC block level. Still, we are continuing to track this in depth, including the ongoing anti-dumping (AD) investigation and potential implications for affected OEMs. 

DG 40 MW, 4-Hour System 

Monthly trend

Weekly Trend (April 6, 2025 - May 18, 2025) 

This month, we present a bonus chart. Because our data view uses medians, it smooths out the sharp, tariff‑driven jumps. A week‑by‑week lens shows how quickly Anza’s continuously updated pricing captures those swings, giving subscribers timely visibility that static price surveys miss. 

Utility-Scale 200 MW, 4-Hour System 

Tariffs eclipsed every cost tailwind this quarter. Falling lithium‑carbonate and incremental efficiency gains could not match the tariffshock, and freight premiums piled on. Compared with January 2025 levels, delivered AC system prices now sit 68% higher in the DG market and 56% higher at utility scale. DC‑only solutions climbed 68% and 69%, respectively. We expect prices to stay volatile until policy clarity returns.

SolarBank Corporation (NASDAQ: SUUN) (Cboe CA: SUNN) (FSE: GY2) ("SolarBank" or the "Company") a leader in distributed solar energy, battery storage, and clean energy infrastructure across North America, announced that further to the announcement of its Bitcoin treasury strategy on June 3rd, it is taking the first step in implementing this strategy by allocating the net cash generated by its Geddes Solar Power Project (the "Geddes Project") to acquire Bitcoin. This positions SolarBank among the pioneering renewable energy companies to adopt a Bitcoin treasury strategy, joining other corporations that have successfully added Bitcoin to their balance sheets.

The Company is evaluating extending this Bitcoin treasury strategy to other solar and battery energy storage projects that it is developing as assets it intends to own as an independent power producer.

How the Solar-to-Bitcoin Model Works:

1. Solar panels at the Geddes facility generate 3.79 MW of DC electricity.
2. Power is sold to community solar subscribers through power subscription agreements.
3. Net revenue after operational costs flows to corporate treasury.
4. Designated portion allocated to Bitcoin purchases based on market conditions.
5. Creates dual value streams: stable energy revenue + digital asset holdings.

The Geddes Project, which has a designed capacity of 3.79 megawatts (MW) DC, is repurposing a closed landfill, addressing two critical challenges: the need for clean energy and the transformation of contaminated sites into valuable assets. The project represents part of SolarBank's broader 1+ gigawatt development pipeline, positioning the company for potential capacity growth over its current 32+ MW of operating assets. The Geddes Project is expected to become operational and commence producing power and revenue before the end of June 2025. The Company will provide specific Bitcoin allocation percentages after the project commences commercial operation.

Dr. Richard Lu commented: "I am pleased we are moving forward with the first step in our Bitcoin treasury strategy. Geddes is the largest power producing assets that SolarBank will have operational and this strategy provides a sustainable way to add Bitcoin to SolarBank's balance sheet. By converting solar energy revenue into digital assets, we're creating a unique value proposition that combines the stable cash flows of renewable energy with the potential appreciation of Bitcoin, while supporting grid decarbonization and distributed energy resources (DER) expansion."

Strategic Rationale and Market Opportunity

SolarBank's innovative approach leverages several key market trends:

• Growing institutional adoption of Bitcoin as a treasury reserve asset.
• Increasing demand for distributed solar and battery storage solutions.
• Enhanced revenue opportunities from renewable energy projects.
• Rising importance of energy resilience and microgrid capabilities.

The actual timing and value of Bitcoin purchases, under the allocation strategy will be determined by management in its discretion based on the net cash produced by the Geddes Project after taking into consideration capital and operating costs, and debt service obligations. Purchases will also depend on several factors, including, among others, general market and business conditions, the trading price of Bitcoin and the anticipated cash needs of SolarBank. The allocation strategy may be suspended, discontinued or modified at any time for any reason. As of the date of this press release, no Bitcoin purchases have been made.

Fine Airport Parking, a leader in premium off-airport parking services, announced that it has selected Zevtron, a cutting-edge electric vehicle (EV) charging technology provider, to deliver scalable and infrastructure-friendly EV charging at its two facilities serving George Bush Intercontinental Airport (IAH) in Houston.

As part of the initial deployment, Zevtron will install 16 chargers supporting 32 EV charging ports across both garages. Each charger will be powered by Zevtron’s white- labeled operating system, which provides Fine Airport Parking total control over who can use chargers and how they can be used, while also allowing the company to monetize EV charging. Zevtron’s platform is hardware agnostic, so it can be implemented to manage existing chargers at Fine Airport Parking locations, as well as the Zevtron chargers being deployed now at George Bush International Airport. Because it’s white labeled, the platform will allow Fine Airport Parking to expand their brand into EV Charging.

“Zevtron’s platform is by far the most innovative, user-friendly, and cost-effective EV charging solution we’ve come across,” said John Davey, Senior VP of Marketing and Strategy for Fine Airport Parking. “Because it’s fully customizable, it will give us complete control over how we manage and monetize our EV assets.”

Zevtron is implementing an innovative low-power charging system that allows multiple vehicles to be charged from a single 40-amp electrical feed, delivering multiple-port functionality per device. This approach enables Fine Airport Parking to leverage its existing electrical infrastructure with no additional utility or infrastructure upgrades—making the transition to EV support fast, efficient, and cost-effective. This creative approach enables parking owners and institutions to “right size” their operations, providing a customized charging approach that meets the owner’s unique needs while supporting the rapid growth of electric vehicle adoption. And it makes EV charging technology much more affordable and accessible to smaller operations and owners who have experienced sticker shock in the past from the prices of legacy EV charging technology providers.

“The Zevtron platform also has the scalability we need so the system will grow with us,” said Davey. “Being able to include EV charging with our reservation platform or implement pricing strategies will be extremely beneficial to us, as well as to our customers. Zevtron is giving us a turnkey solution that will allow us to easily recoup our investment because of the level customization they offer.”

Zevtron’s dual-port, low-power approach represents a breakthrough in EV infrastructure that emphasizes smarter and more efficient use of existing resources. This slow-charge approach is also perfect for airports because travelers typically park for several days at a time.

“Fine Airport Parking is one of America’s leading independent parking owner/operators, and we’re proud to support their EV infrastructure strategy,” said Bob Andrews, Zevtron’s founder. “Our platform is designed to offer seamless scalability, smart energy management, and powerful customization tools—making it ideal for owners and operators looking to deliver premium EV charging without breaking the grid or the budget.”

Following the successful deployment at IAH, Fine Airport Parking plans to roll out Zevtron EV charging solutions at its Hobby Airport location in Houston, followed by facilities serving Denver International Airport and Tulsa International Airport.
