ViZn Energy Systems Selected to Provide Commercial-Scale Flow Battery in Central America

“200kW / 800kWh battery to be paired with solar to achieve significant OPEX savings at a world class resort in Nicaragua”

AUSTIN, TX – ViZn Energy Systems Inc. (ViZn), a leading provider of energy storage systems for utility, commercial and industrial (C&I), and microgrid applications has been selected to provide a 200kW (four hours) flow battery in Central America. The versatile zinc-iron redox battery from ViZn is being combined with an 800kWp solar array that will enable the Rancho Santana resort to take advantage of multiple behind-the-meter services, giving an estimated payback on the system of six and a half years.

“Electricity in Nicaragua is amongst the most expensive in Latin America and many C&I customers there are on a grid tariff with a peak rate between 6 pm and 10 pm when the energy usage spikes,” said Ron Van Dell, President, and CEO of ViZn Energy Systems. “There is also no net metering for excess solar electricity, so our four-hour battery is a strong match for the market because it enables customers to install larger PV systems, get significantly cheaper energy than the grid rates, and mitigate elevated energy and demand rates during the evening network peak.”

Rancho Santana is a world-class resort and residential community covering 2,700 acres on the Pacific Coast of Nicaragua. The property has 152 homes and an additional 17 rooms and load is growing every year. PELICAN, S.A., an EPC based in Nicaragua, will be installing the PV system and integrating it with the ViZn flow battery and backup diesel generators.

“Our annual utility expenses are growing and we are exposed to significant peak demand charges, so we had to find a way to sustainably reduce our energy costs without impacting the sensitive environment at the resort,” said Rancho Santana CEO Matt Turner. “PELICAN proposed an innovative solar+storage system that will allow us to save over $250,000 per year on our utility bills. Using the non-toxic ViZn batteries for the energy storage not only alleviates any of the environmental concerns but also provides excellent ROI.”

Allan Cruz and Lâl Marandin are the co-founders of PELICAN and they said, “Rancho Santana came to PELICAN for help. We’ve been working with them to identify the best solar+storage solution and after evaluating numerous storage options, ViZn had the most economically attractive system. ViZn was awarded this project because its versatility to provide both power and energy services gave us confidence the asset would be able to accommodate future growth at the resort.”

The ViZn energy storage system is a self-contained solution that does not require cooling systems and is easily interconnected to meet higher power and energy requirements. ViZn Energy’s flow batteries experience zero capacity fade over 20 years and they have full access to 100% of their state of charge, giving them significantly more usable output than competitive batteries. Uniquely, they are also capable of performing both rapid, high-power discharges and slower, long-duration releases at lower power (unlike other storage technologies that can only do one or the other). This enables utilities, C&I customers, and other end users to stack applications and incorporate multiple value streams. The inherently safe zinc-iron chemistry uses globally abundant materials and is non-flammable, non-toxic and easily recyclable at the end of life.

ViZn’s New 20 Year Warranty and 95% Power Guarantee Sets the Bar for Stationary Energy Storage

AUSTIN, Texas – October 4, 2016 – ViZn Energy Systems Inc. (ViZn), a leading provider of non-toxic flow battery energy storage systems, announced today that it is offering an optional 95 percent power guarantee on their large scale energy storage systems for up to 20 years. This guarantee will be available to supplement ViZn’s best-in-class comprehensive warranty which is offered in multiple durations up to 20 years, twice the industry average. The guarantee is straightforward, simple, and is independent of battery duty cycle or energy throughput.

“Lithium-ion battery life and their constrictively weak warranties have been one of the limiting factors for the widespread adoption of energy storage,” said Ron Van Dell, CEO of ViZn Energy Systems. “Our flow batteries have been thoroughly evaluated by Black and Veatch for longevity and performance over a long system life. The system’s long term warranty and ability to deliver 95 percent of the rated power for 20 years will give utilities, developers, and banks confidence that their energy storage is engineered to last as long as the infrastructure or generation system it is typically coupled with. We hope to bring simplicity and consistency to a space that has been riddled with partial-coverage warranties.”

ViZn’s unprecedented guarantee is made possible because, unlike lithium-ion batteries, their flow batteries avoid traditional wear out mechanisms that can degrade battery power and capacity over time. Contrast this with other stationary storage systems that are frequently oversized up to 40 percent to account for anticipated power losses and have life-limiting dependencies on temperature, discharge power, and cycle count. In economic terms, developers, installers, and integrators can count on a ViZn Energy stationary storage system to provide unmatched ROI as it delivers high power services and high energy capacity for the life of their system. There is no longer a need to account for added costs such as cell replacement, out-of-coverage O&M, and reduced performance like with a typical lithium-ion system.

ViZn’s flow batteries are manufactured by Jabil’s ISO 9001-certified production team in Florida and the technology utilizes a non-toxic, low-cost zinc and iron chemistry that makes sighting and permitting relatively painless. Unlike lithium-ion systems, ViZn’s versatile flow batteries are capable of performing both high-power and long-duration applications, which allows end users to incorporate multiple value

streams and realize more favorable ROI than other energy storage technologies. ViZn is currently building the largest flow battery in North America and is on track to be the largest global producer of flow batteries by the end of the year.
