What is Engineering for Scale?

Engineering for scale looks to bring the traditional advantages of economies of scale to the energy storage system (ESS) market, through use of standardization and open standards.

WHAT DOES “ENGINEERING FOR SCALE” MEAN AND WHY DOES IT MATTER?

A Brief Story

About the time 1Energy Systems [now Doosan GridTech] was founded in 2011, a story circulated of a community energy storage (CES) project that was being installed. The system featured a 25kWh battery and was reported to cost around $100,000. At nearly the same time, Nissan was launching their Leaf which featured a 24kWh battery, and a car, for around $35,000. What was the difference? The CES was a one-off project and the Leaf was engineered for scale.

Modular Energy Storage Architecture (MESA)

MESA is the effort to define open communication and information standards in the energy storage industry. The MESA Alliance is open to all interested utilities, industry vendors and stakeholders. The group’s first specification, MESA-Device, is available in draft form on the MESA website. For more information and to get involved with this important effort, visit the MESA website.

ENGINEERED FOR SCALE HAS TWO KEY ELEMENTS: STANDARDIZATION AND OPEN STANDARDS.

Standardization is about identifying the parts of the system that are commodities and agreeing on a common way that they will be done. To use an electricity example, think about the light bulb and the size of the base that screws into the socket.

Standardization eliminates complexity that isn’t justified by the innovation potential in that part of the system. It enables volume suppliers to drive costs way down for those components, since they can make them in very high volumes for use by all of the downstream products in the market. Standardization also improves safety by simplifying the training needed for personnel operating the product.

OPEN STANDARDS

Open Standards are defined, publicly available specifications for how different elements of a system will communicate with each other. In energy storage, open standards provide two main benefits. Well defined open standards divide a complex system into discrete components where industry can focus its proprietary innovation and then enable that innovation to come together through publicly documented interfaces that are consensus driven. They lower costs by reducing project-specific engineering, and they increase choice by allowing customers to choose systems built from interoperable components rather than buying a “black box” system from a single vendor.

Non-recurring engineering (NRE) is the engineering that gets done for a project that is specific to that job. In energy storage projects, this NRE can occur at multiple levels. It can occur within the system connecting battery type A with power conversion system B and control software C. And it can occur connecting the system as a whole to SCADA system X at one utility versus SCADA system Y at another. The more the industry can agree on how these different parts will communicate with each other in advance, the less custom integration work will be needed on each project that is built from their various products.

Open standards also give customers the flexibility to combine the components that are best suited for their project without having to buy a “black box” from a single vendor. For an example of this second benefit, think of an open standard like Bluetooth. Before Bluetooth, you often had to buy all of your mobile phone accessories from the company that sold you their handset. Today, if you buy a Bluetooth compatible phone, you know that any accessory that supports that standard will connect to your phone.

Open standards = more choices for customers.

At the heart of every energy storage system are three essential components – a storage medium, a power conversion system and the control software that orchestrates the overall system.
