Wärtsilä introduced that it acquired a contract to provide an engineered tools supply (EEQ) of a 40-MW / 80-MWh DC-coupled storage system to the 200-MW Hickory Park Solar challenge in Georgia, USA.

Project proprietor RWE Renewables stated with the addition of the dispatchable storage resolution, it will likely be in a position to promote practically the entire 200 MW of technology from the photo voltaic PV to Georgia Power Company.

Wärtsilä’s GEMS Digital Energy Platform will management the hybrid plant. GEMS screens, synchronizes, and optimizes technology belongings at increments of 100 milliseconds, utilizing machine studying and historic and real-time information analytics to calibrate the kind of technology wanted at any particular time, all underneath a single portfolio. 

Wärtsilä’s auto-bidding resolution “IntelliBidder” implies that Hickory Park Solar will have the ability to present Georgia Power a day-ahead firming photo voltaic plus storage profile, which can enhance the predictability of the intermittent technology. Cloud-based IntelliBidder makes use of machine studying and algorithms primarily based on automated and forecasted information, taking real-time buying and selling and mixing it with a wise management platform that gives value-based asset administration and portfolio optimization. 

Wärtsilä will present its GridSolv Quantum vitality storage system to the challenge. It is at present designed with CATL batteries. GridSolv Quantum is a modular system that allows the ESS, whereas sustaining a minimalist design. It additionally delivers the bottom lifecycle prices and the smallest system footprint, in accordance with the corporate.

The co-located vitality storage system shall be DC-coupled with the photo voltaic system, permitting a number of advantages, reminiscent of improved system effectivity, decrease steadiness of plant prices, and clipped photo voltaic recapture. With storage connected to the photo voltaic system, the batteries will be charged with extra photo voltaic technology when the PV reaches its peak and would in any other case start clipping. The saved vitality will be launched into the grid on the applicable time, maximizing the worth of the system’s technology, stated Wärtsiliä.

“For us, this can be a milestone challenge of renewable integration involving photo voltaic PV plus vitality storage, with the batteries being charged fully from the photo voltaic system. It is likely one of the only a few initiatives globally on this scale utilizing DC-coupling,” commented Andy Tang, Vice President, Energy Storage and Optimisation, Wärtsilä Energy. 

Delivery of the Wärtsilä tools is scheduled for September 2021, and the plant is predicted to begin business operations in November.
