younicos

Younicos 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 innovative Y.Cube systems. They will be managed by Younicos’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 Y.Cube deployment in the U.S. to date.

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 optimizing 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 neighborhood in East Austin, coexisting near both residential and commercial buildings. The Y.Cube, which has been optimized 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.

“We’re keeping Austin weird – and energized,” said Stephen L. Prince, CEO of Younicos. “The SHINES project is the perfect showcase for an alternative, distributed energy system with resources like energy storage providing resiliency and security. Our Y.Cube is ideal for this 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.”

“Integrating energy storage with solar is becoming essential as we achieve our utility’s goal of 55% renewable energy by 2025,” says Karl Popham, Austin SHINES Principal Investigator and Manager of Emerging Technologies at Austin Energy. “The Austin SHINES program is more than a technical pilot; it is phase one of a larger rollout to maximize the value of distributed energy resources for our customers and the utility. Ultimately, it’s about clean energy being even more affordable and reliable.”

Daejin Choi, CEO of Doosan GridTech commented, “We are pleased to be working with Younicos on this breakthrough project. The Modular Energy Storage Architecture (MESA) open standard provides the software architecture that allows us each to bring our innovation to Austin Energy without a lot of custom engineering to fit the pieces together. Austin preserves choice in their system moving forward and we each get to focus on our core competencies.”

Solar-plus-storage microgrid now live at Panasonic’s Denver operations hub

Younicos has commissioned a 1 MW / 2 MWh lithium-ion battery system in partnership with Panasonic and Xcel Energy. The news was announced at the Energy Storage Association’s 27th Annual Conference, which offered two delegate group tours of the multi-resource microgrid.

The system is located at Peña Station NEXT, a transit-oriented smart and sustainable development in Denver. Panasonic Enterprise Solutions Company and Panasonic CityNOW is the anchor corporate tenant and lead technology partner. A unique solar+storage microgrid is at the heart of the development’s energy solutions. Representing a model for utility and commercial and industrial (C&I) microgrids, the project benefits various stakeholders and the power grid by providing renewables integration, grid resilience, and multiple grid support and operational services, such as peak demand reduction and frequency regulation.

Four Younicos Y.Cubes have been connected to the Xcel Energy power grid, creating a one-megawatt (MW) battery storage resource enabled by Younicos’s intelligent Y.Q control software. The system’s multi-mode operating capability makes it possible to derive maximum benefits from the 1.6 MWdc solar PV system located on a nearby carport, along with 259 kWdc of PV on the building’s rooftop. Panasonic’s operations hub building, which has an intelligent building energy management system, is serving as the initial anchor load for the microgrid.

“This portfolio microgrid is a smart, resilient, and clean energy resource, not just for Panasonic’s Denver operations hub, but also for the broader Peña Station NEXT development,” said George Karayannis, VP of Panasonic CityNOW. “It has been a pleasure to collaborate with Younicos and Xcel Energy to realize this innovative project.”

Each Y.Cube is an integrated “plug-and-play” solution that comprises two sub-enclosures, one each for the power conversion system (PCS) and DC battery block. Y.Cubes are available in 250 or 500 kVA modular building blocks that can be deployed individually in smaller applications or combined to create multi-megawatt systems.

Panasonic, Younicos working on solar+storage project in Denver

Energy storage company Younicos has signed an agreement with strategic partner Panasonic to design and build a solar-plus-storage system at Peña Station NEXT in Denver, Colo., which includes the operations hub for Panasonic Enterprise Solutions Company and Panasonic CityNOW. The system will make use of multiple Younicos Y.Cubes, the innovative “storage-in-a-box” solution for C&I applications from the German-American industry pioneer.

The project calls for four Y.Cubes to be installed at the Panasonic facility in Denver, Colorado. The one-megawatt (MW) storage resource, which will be connected to the Xcel Energy power grid, will provide frequency regulation, solar grid integration through ramp control, grid peak shaving, energy arbitrage, and backup power – enabled by Younicos’s intelligent Y.Q storage control software. This multi-mode operating capability will enable Panasonic, Xcel Energy, and other microgrid stakeholders to derive maximum benefits from Xcel Energy’s 1.6 MW solar PV system sited on a parking structure nearby, along with 259 kW of PV on the building’s rooftop.

“The solar-plus-storage microgrid is an anchor, not just of Panasonic’s new Denver operations hub, but also for the broader Peña Station NEXT development, which is a 400-acre, smart and sustainable transit-oriented development in Denver,” said Jamie Evans, managing director of the Energy Solutions Group at Panasonic Enterprise Solutions Company. “We are excited to partner with Younicos and Xcel Energy to bring this innovative project to life.”

“We’re very pleased to work with Panasonic on this project, which highlights the advantages of our plug-and-play Y.Cube system for commercial and industrial use cases,” said Stephen Prince, Younicos CEO. “Like Younicos, Panasonic is a technology leader with a strong focus on the benefits of solar-plus-storage for different applications. They and the local grid will benefit enormously from this resource.”

The Y.Cube consists of two sub-enclosures, one each for the power conversion system and DC battery block. The controls are embedded in the PCS and communicate directly with the battery system, bypassing the need for additional battery-to-PCS communication interfaces. Its optimized configuration translates to ultra-fast response time for improved PCS efficiency and enhanced grid-forming capability.

The Y.Cube is available in 250 or 500 kVA modular building blocks that can be deployed individually in smaller applications or combined to create multi-megawatt systems. Its compact size allows for easy installation. No on-site crane is needed; installation can be done with a forklift, saving considerable time and money.
