Younicos deploys Y.Cubes for low-cost distributed solar in Texas

30.05.2017

Younicos has announced that the company has signed an agreement to deliver a megawatt-scale battery storage system to Austin Energy, as part of a U.S. Department of Energy (DOE)-funded initiative known as the Sustainable and Holistic Integration of Energy Storage and Solar PV (SHINES) project.

Younicos will collaborate with the project’s prime contractor, Doosan GridTech, to install the 1.75 MW / 3.2 MWh system using the company’s Y.Cube systems. According to Younicos, they will be managed by the company’s Y.Q software platform, communicating with the Doosan GridTech Intelligent Controller using the MESA (Modular Energy Storage Architecture) open standard. The seven Y.Cubes and Y.Converters represent the company’s largest deployment in the U.S. to date.

“The SHINES project is the perfect showcase for an alternative, distributed energy system – and it shows how energy storage can provide optimal resiliency and security for such systems”, said Stephen L. Prince, CEO of Younicos. “Our Y.Cube is ideal for this type of application – offering the best in battery storage, intelligent control, system performance and safety in a compact form factor. We’re very pleased to partner with Austin Energy and Doosan GridTech on this innovative project.”

“This project is yet another important proof point of the versatility of batteries and the importance of the right software. Looking at the more than 200 MW of storage that we have commissioned or under construction, it is becoming clear that ever more energy market participants are appreciating the value that storage can bring to them, leading to an increased demand for solutions that are at once flexible and standardised.”

The Y.Cube systems will provide storage capabilities as part of a Distributed Energy Resource Management System (DERMS) that will maintain grid reliability while also enabling energy loads to be delivered at the lowest possible cost with high penetration levels of distributed PV generation. The platform, called DG-DERO™, also provided by Doosan GridTech, will use multiple advanced control methodologies that will be demonstrated and evaluated using a fleet of diverse DER assets deployed at various locations among Austin Energy’s customers.

In addition to optimising battery performance in combination with solar PV, a key requirement of the project is compliance with strict safety standards. The battery system will be located in a neighbourhood in East Austin, coexisting near both residential and commercial buildings. The Y.Cube, which has been optimised for use in commercial and industrial battery storage applications, is a plug-and-play system that also contains multiple thermal management subsystems for maximum safety.

“Integrating energy storage with solar is becoming essential as we achieve the City of Austin’s goal of 55 percent renewable energy by 2025. The Austin SHINES program is more than a technical pilot; it’s phase one of a larger rollout to maximise the value of distributed energy resources for our customers and the utility. Ultimately, it’s about testing innovative technologies that could have long-term benefits,” said Jackie Sargent, Austin Energy General Manager.
