ViZn Energy Systems Enables 24/7 “Solar Nights” at Lowest Ever Published Cost

Utility scale solar and wind power "on-demand" for 33 percent less than coal

AUSTIN, Texas - July 11, 2017 - ViZn Energy Systems Inc. (ViZn), a leading provider of utility scale energy storage systems, is working to make the sun shine all night by integrating its zinc iron flow battery storage system for a record low price of 4¢/kWh. A ViZn 30 MW, 4-hour system added to a 100 MW solar plant can generate a seven percent internal rate of return (IRR) with a 4¢/kWh power purchase agreement (PPA) - 20 percent below the lowest published values.

Now, utilities can add energy storage to a wind or solar farm at a lower price than coal-fired generation (6¢/kWh per Bloomberg New Energy Finance), paving a clear path toward 100 percent renewable penetration. This calculation is independent from any additional revenue streams derived from the ancillary services made possible by ViZn battery systems.

"The lowest cost and most abundant energy now comes from solar and wind, and these systems can now produce power 24/7 because of energy storage. More importantly, ViZns flow battery systems do it at a fraction of the cost of lithium ion. "Solar Nights™" are now a reality and they are powered by clean, domestically produced, low cost, and infinitely available energy," stated Ron Van Dell, CEO of ViZn Energy Systems.

Currently, leading lithium ion batteries last for only 7 to 10 years and are engineered to provide either one energy service-focused or one power service-focused cycle per day. ViZns full-service zinc-iron flow battery system can deliver both power and energy services for 20 years with no fade and can operate two, full-duty cycles per day. ViZns versatility uniquely enables utilities to balance intermittent renewable energy while dispatching to address high value ancillary services such as frequency regulation, spinning reserve, transmission and distribution deferral, black start, and congestion relief.

"Nearly every utility daily demand curve in the world has a morning peak and a late afternoon peak and almost every solar and wind farm is financed for a 20-year economic lifetime. It is not hard to understand how a fade-free battery that delivers two cycles per day for 20 years is able to contract for output at record low energy storage system prices," further commented Van Dell.

ViZn is currently delivering systems in the U.S., Canada, Central America, Europe, and India. ViZn Energys flow batteries experience zero capacity fade over 20 years and they have full access to 100 percent of their state of charge, giving them significantly more usable output than competitive batteries. They are also uniquely capable of performing both rapid, high-power discharges and slower, long-duration releases at lower power - unlike other comparable storage technologies which can only do one or the other. The inherently safe zinc-iron chemistry uses globally abundant materials and is non-flammable, non-toxic, and is easily recyclable at the end of its life.

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
