New Node Architecture and Upgraded Controls Offer Highest Reliability with Lowest Total Cost of Ownership for Utilities, Developers and Power System Operators

ARLINGTON, Va., November 13, 2015The AES Corporation (NYSE: AES) today announced the first deployment of Advancion™ 4, the next generation of battery-based energy storage, at the Warrior Run facility in Cumberland, Maryland. Advancion is a complete, battery-based alternative to peaking power plants that provides a dependable, smart and cost-competitive means to modernize power systems.

Advancion 4 is among the most proven energy storage platforms available, resulting from AES’ more than eight years of commercial experience operating grid-connected energy storage. This latest design includes improvements in the architecture that provide the highest levels of reliability, upgrades to the already proven controls platform, and a modular design to drive down the upfront and on-going costs of these advanced storage assets for customers.

“With the addition of the Warrior Run Advancion Energy Storage Array, we now have 64 MW of interconnected energy storage in PJM,” said Ken Zagzebski, President of AES’ US Strategic Business Unit. “We continue to see energy storage as an important innovative technology for serving our customers with safe, reliable, cost effective and emission free power.”

“Advancion 4 was developed to address the challenges faced in owning and operating the largest fleet of advanced battery-based energy storage projects,” said John Zahurancik, President of AES Energy Storage. “AES has a history of providing our customers with innovative solutions, and Advancion 4 raises the bar, as it delivers the highest reliability, has the lowest total cost of ownership, and is available to utilities, developers and power system operators to own directly or through a managed service contract.”

Key Features of Advancion 4 include:

  • Modular,  Compact Advancion Array – The Advancion 4 Array now has an industry-leading compact footprint and optimized design that is five times denser than prior installations, further reducing the total installed cost by requiring less space and balance of system costs. Advancion 4 arrays are engineered to accommodate interchangeable supplier components. These suppliers build to meet Advancion design specifications to avoid costly, per project system integration and are prequalified through AES’ Advancion Supplier Certification Program. A select group of high quality component suppliers have already been certified and the group represents more than half of the global advanced battery production. The modular architecture enables replacement and augmentation over the system life using the best new technologies at the best future price.
  • Introducing the Advancion Node – The new Advancion Node is the smaller, more manageable building block for Advancion Arrays. These independent, modular units incorporate pre-certified batteries and inverters, with AES controls, and are architected in a massively parallel design – offering customers the highest level of reliability and availability, similar to the world’s best datacenter systems. The scalable design allows for standard configurations from 100 kW to over 1,000 MW, and from 15-minutes of duration to over four hours without any reengineering.
  • The Next Generation Advancion Digital Control System (DCS) – The addition of the node architecture to AES’ patented control platform provides owners with unprecedented control of the asset, to maximize revenue and reduce operating costs. Advancion-based solutions now monitor, record and analyze thousands of individual points within the system to tune performance – all protected within a robust cybersecurity framework. For example, the Warrior Run installation regularly measures and records nearly 80,000 separate data points, representing more than two terabytes of data per year. This node-level control makes it possible for parts of the same array, or several distributed arrays, to do mix and match applications and to load balance service requirements (e.g. regulation, reserves, renewable ramping, energy delivery, voltage control, etc.), optimizing the operation of the asset.

“The Advancion 4 energy storage solution is a unique combination of market-tested controls and a massively parallel design architecture, incorporating best in class technology components. Every aspect has been developed to meet the needs of a long-term power asset owner-operator,” said Brett Galura, Vice President of Solution Development for AES Energy Storage. “We are especially pleased to work with our initial certified suppliers, LG Chem and Parker Hannifin, in this first commercial deployment of Advancion 4.”

The Warrior Run Advancion Energy Storage Array is the largest grid-scale battery, and one of the largest green technology projects, in Maryland, providing 10 MW of interconnected energy storage, equivalent to 20 MW of flexible resource. Warrior Run will provide critical grid stability services in the form of frequency regulation service to the PJM Interconnection, which controls the power grid for more than 61 million people.

AES has a total of 384 MW of interconnected energy storage, equivalent to 768 MW of flexible resource, in operation, construction or late stage development in six countries. AES has accumulated nearly three million megawatt-hours of delivered service on its advanced energy storage platform.
