8 terms

distributed generation technical

"acquisition of eight late-stage 9.9 MW distributed generation (DG) battery energy storage projects"

Electricity produced close to where it is used rather than at a large, central power plant—examples include rooftop solar, small wind turbines, and local gas generators. For investors, distributed generation matters because it can change how power is bought and sold, reduce demand for traditional utility services, create new revenue streams for installers and technology providers, and expose assets to different regulatory and reliability risks, like a neighborhood adding many home solar systems.

battery energy storage systems technical

"developer, owner, and operator of utility-scale and distributed battery energy storage systems (BESS)"

Large, grid-connected rechargeable battery systems that store electricity for later use, like a giant household battery for cities or power plants. They matter to investors because they help balance supply and demand, enable more renewable energy, reduce outage risk, and create revenue through services such as selling stored power at peak times or participating in grid stability programs, while requiring upfront capital and having performance limits tied to lifespan and degradation.

ercot technical

"strategically positioned in the ERCOT South region of Texas"

The Electric Reliability Council of Texas (ERCOT) is the organization that operates and balances the bulk electric grid for most of Texas, acting like an air-traffic controller that matches electricity supply and demand across the state and runs the wholesale power market. Investors care because ERCOT’s decisions, grid reliability, and market prices directly affect the revenues, costs, and risk exposure of utilities, energy producers, large consumers, and companies whose operations depend on stable, affordable power.

lithium-based utility-scale batteries technical

"The projects will use RelyEZ’s lithium-based utility-scale batteries."

Large-scale energy storage systems that use lithium-based battery cells to store electricity for the power grid; think of them as giant rechargeable power banks that can absorb excess generation and release it when demand rises. They matter to investors because they enable more reliable electricity delivery, help integrate renewable energy, earn revenue through services like peak shaving and frequency support, and can change the economics of power generation and transmission over time.

frequency regulation technical

"provide critical services including frequency regulation, voltage support, energy arbitrage"

Frequency regulation is a process that helps maintain the stability of an electrical grid's power supply by adjusting the output of power sources to keep the overall system's frequency steady. It’s similar to how a thermostat keeps a room at a consistent temperature by making small adjustments. For investors, reliable frequency regulation ensures a stable and efficient electricity supply, which is essential for the smooth operation of many industries and markets.

voltage support technical

"provide critical services including frequency regulation, voltage support, energy arbitrage"

Voltage support is the set of equipment, controls and actions that keep the electrical voltage on a power grid within a safe, steady range so devices and machinery run reliably. Think of it as the grid’s cruise control and shock absorbers that prevent sudden dips or spikes; for investors, effective voltage support reduces outage risk, limits equipment damage, helps meet regulatory standards and can create revenue or cost obligations through grid services and reliability contracts.

energy arbitrage technical

"provide critical services including frequency regulation, voltage support, energy arbitrage"

Energy arbitrage is the practice of buying electricity or fuel when prices are low and selling or using it when prices are higher, often by storing energy in batteries or scheduling flexible demand. Like buying groceries on sale to use later, it turns price swings into profit or savings. Investors care because it creates a predictable revenue stream and affects the value and returns of storage, generation and grid-related businesses by capturing price differences across time or places.

peak capacity support technical

"critical services including frequency regulation, voltage support, energy arbitrage, and peak capacity support."

Support provided to handle short-term surges in demand for a product, service, or facility—such as extra manufacturing shifts, temporary staff, backup equipment, or modular capacity. Investors care because it shows whether a company can deliver when demand spikes without long delays or costly bottlenecks; strong peak capacity support can protect revenue and reputation, while weak support can lead to lost sales, higher costs, or regulatory scrutiny.

Newport Beach, CA, March 03, 2026 (GLOBE NEWSWIRE) -- Bimergen Energy Corporation (NYSE American: BESS, BESSWS), a developer, owner, and operator of utility-scale and distributed battery energy storage systems (BESS) across the United States, today announced the acquisition of eight late-stage 9.9 MW distributed generation (DG) battery energy storage projects from Aggreko’s IPP Solutions business, strategically positioned in the ERCOT South region of Texas. The acquisition of these development projects further demonstrates the strength of Bimergen’s growth strategy. The acquisition was financed through Bimergen’s JV with RelyEZ. The projects will use RelyEZ’s lithium-based utility-scale batteries.

The portfolio represents approximately 79.2 MW of total nameplate capacity and quickly expands Bimergen’s advanced development pipeline. Five projects are anticipated to achieve In Service Date (ISD) in late 2026, with the remaining three expected in early 2027. The projects are strategically positioned to provide essential grid stability, support renewable integration, and address accelerating power demand in one of the nation’s fastest-growing and most capacity-constrained energy markets.

Bimergen plans to award construction contracts for the projects in the near future, advancing the portfolio into the build phase and reinforcing the Company’s execution momentum toward commercial operation.

“The acquisition and simultaneous closing of these eight late-stage 9.9 MW DG projects represents a major milestone for Bimergen and significantly strengthens our presence in the high-opportunity ERCOT market,” said Cole Johnson, Co-CEO and President of Bimergen Energy. “Closing these assets with our financing parties underscores the depth of our industry relationships and our ability to efficiently advance strategically positioned projects toward near-term revenue generation.”

“This transaction highlights the scalability of our distributed storage strategy and the alignment we have built with our industry partners,” added Bob Brilion, Co-CEO of Bimergen Energy. “By incorporating these advanced-stage DG assets into our portfolio in a simultaneous closing, we are positioning Bimergen to capture substantial value while contributing meaningfully to Texas’ evolving energy landscape.”

ERCOT South continues to experience robust demand for flexible energy resources driven by economic growth, industrial expansion, and rising renewable penetration. Bimergen’s expanded distributed generation footprint aligns with the Company’s strategy to develop, own, and operate standalone BESS projects that provide critical services including frequency regulation, voltage support, energy arbitrage, and peak capacity support.
