Snohomish County PUD Launches Second Energy Storage System

Jason ZyskowskiNeil Neroutsos | Jul 12, 2017

Snohomish County Public Utility District (PUD) has brought on-line its second energy storage system at a utility substation. The battery storage systems aim to transform the marketplace and how utilities manage grid operations. They also are designed to improve reliability and the integration of renewable energy sources, which are rapidly growing in the Pacific Northwest region of the United States.

The projects were made possible in part by a US$7.3 million investment from the Washington State Clean Energy Fund. The Snohomish County PUD’s systems are built using an innovative approach known as Modular Energy Storage Architecture (MESA). It offers a nonproprietary and scalable approach to energy storage. What sets MESA apart from other energy storage efforts is it uses standard interfaces between equipment components, such as the power conversion system, batteries and control system. These provide utilities more choices, reduce the complexity of projects and, ultimately, lower costs.

An industry consortium of electric utilities and technology suppliers developed MESA for the purpose of clearing barriers to growth in energy storage. More than 30 organizations have joined the MESA alliance as members or partners, including Snohomish County PUD, Seattle City LightPacific Northwest National Laboratory (PNNL), Duke EnergyDoosan GridTech and General Electric.

MESA Standards Alliance Publishes Specification for Utility Control of Grid Scale Energy Storage

(SAN FRANCISCO, Ca., November 15, 2016) – The MESA Standards Alliance (MESA) has released the first draft of a protocol for communications between utility control centers and energy storage systems (ESS). The open, non-proprietary specification, referred to as MESA-ESS, provides a standard framework for utility-scale ESS data exchanges. Specifically, the draft addresses ESS configuration management, ESS operational states, and the applicable ESS functions from the IEEE 1815 (DNP3) profile for advanced distributed energy resources (DER).

“MESA-ESS enables electric utilities or grid operators to scale deployment of energy storage and manage energy storage assets and fleets of multi-vendor assets to meet specific needs and use cases with minimal custom engineering,” said Mike Rowand, Director of Technology Development at Duke Energy and MESA’s Board Chair. “As energy storage systems multiply on utilities systems, MESA’s work will greatly reduce the complexity of managing these distributed assets.”

The MESA-ESS specification is an important step in supporting the use of non-proprietary communication standards, promoting interoperability, and minimizing the amount of non-recurring engineering that is required to integrate an ESS into utility control systems using DNP3. The draft specification was developed by a technical work group of MESA members, partners, and staff over the last 18 months based on the work by the DNP Users Group. MESA’s draft specification can be downloaded for review and testing; utilities, vendors, and other stakeholders are encouraged to provide feedback for incorporation into future versions. Additionally, this work will feed into a larger effort to update the existing DNP3 Application Note on distributed energy and storage, which is expected to be completed in 2017.

“MESA’s work to standardize energy storage system communication requirements builds upon and complements previous efforts in this area. This is an important body of work for the Users Group to consider as we update the DNP3 Application Note,” said Ron J. Farquharson, President for the DNP Users Group. “We appreciate MESA’s efforts to jumpstart the process to improve communications for storage systems and we look forward to continuing the collaboration.”

More information and the draft specification can be found at www.mesastandards.org. The Technical Work Group will be accepting public input throughout 2017 and subsequent drafts and updates will be posted on MESA’s website. For more information about the DNP Users Group visit: www.dnp.org.

Nuvation Battery Management System Selected by Stalwart Power

 

“Stalwart Power had sourced battery modules that met our utility client’s needs in terms of both cost per kilowatt-hour and cycling capacity, but the OEM battery management system was simply not designed to support our deployment at the utility. A key requirement was for the BMS to enable remote monitoring of the BESS and to flag any potential issues that would merit a service call, before it impacted system safety or performance.”

Woody Gibson, CEO, Stalwart Power

battery-energy-storage-system-pv-smoothingSunnyvale, California. November 10, 2016. Stalwart Power has selected Nuvation BMS™ to manage their 51.2-Volt Battery Energy Storage Solution (BESS) for grid-attached and behind the meter energy management. The Stalwart BESS that was fitted with a Nuvation battery management system is a 17.5kWh lithium-iron phosphate energy storage system that utilizes a Schneider inverter. It was deployed in September by a leading U.S. utility to apply PV smoothing and load balancing to solar power generation. Nuvation BMS™ was selected due to its design for utility-scale applications and Nuvation’s ability to provide system integration support and engineering design services. Decisive factors that influenced Stalwart Power’s selection of Nuvation BMS™ included the availability of Ethernet communications, the high configurability of the BMS, and remotely accessible system controls. Nuvation performed all system integration, which included replacing the OEM BMS that came bundled with the battery modules. Their software team also developed PV smoothing and load balancing algorithms and installed a custom site controller into the BESS.

“Stalwart Power had sourced battery modules that met our utility client’s needs in terms of both cost per kilowatt-hour and cycling capacity, but the OEM battery management system was simply not designed to support our deployment at the utility,” said Woody Gibson, CEO of Stalwart Power. A key requirement was for the BMS to enable remote monitoring of the BESS and to flag any potential issues that would merit a service call, before it impacted system safety or performance. In terms of selecting a replacement BMS, the high configurability of Nuvation BMS made it very easy to integrate into Stalwart’s BESS.”

“After about 20 years of doing power engineering projects, we are excited to see the rapid advancements in battery energy storage within the last five years or so,” said Michael Worry, Nuvation CEO.  “We were very pleased to have been selected by Stalwart Power for both our BMS and our engineering services. They have a well-designed BESS and are a company that innovates at a pace that easily keeps up with battery and energy management technology. It was a very rewarding experience to be part of this project, including the installation and bring-up of the BESS at the utility site.”

As variable energy sources such as wind and solar become more widely adopted, it becomes increasingly problematic for utilities to integrate them into distributed electricity grids due to the disruptive impact of these variable power sources on grid stability. As the cost of batteries fall and their performance improves with new chemistries, battery energy storage systems are becoming adopted as a viable solution to this and other energy management challenges being faced by utilities. “PV smoothing” refers to the combining of solar generated power with energy storage to mitigate the impacts of power fluctuations derived from clouds passing overhead. These fluctuations are “smoothed” by the batteries before being sent to the grid. “Load balancing” refers to the storage of excess energy during periods of low demand, and the releasing of that stored energy as demand increases. Energy storage systems in the 48-volt range are emerging as a dominant BESS configuration for residential and commercial energy storage applications. They can be paired with residential solar, for example to store excess energy until needed, aid in grid stability, and power many other applications that directly impact grid energy costs and reliability.

Nuvation Battery Management System Completes MESA Draft 3 Conformance

“Nuvation’s attainment of Draft 3 conformance streamlines the integration of their battery management system with Parker’s MESA-compliant inverters and 3rd-party site controllers on the Alevo GridBank project. As a founding member of MESA, Parker views Nuvation’s adoption of MESA standards and their ongoing involvement as an important step in simplifying the integration of Nuvation BMS into energy storage systems.”

Daniel Friberg, Division Engineering Manager, Parker Hannifin

 

Sunnyvale, California. June 6, 2016. Nuvation Engineering has announced that their battery management system for large-scale energy storage systems (ESS) is now conformant with Draft 3 of the MESA-Device/SunSpec Energy Storage Model. “MESA Draft 3 conformant products share a common communications interface that exposes all the data and control points required for operating the energy storage system,” said John Corman, Vice-President, Engineering and Product Management at Nuvation. “Nuvation BMS can now be integrated with any other MESA-conformant energy storage hardware or software without the custom middleware often required to enable different companies’ products to work together.”

“Nuvation’s attainment of Draft 3 conformance streamlines the integration of their battery management system with Parker’s MESA-conformant inverters and 3rd-party site controllers on the Alevo GridBank project,” said Daniel Friberg, Division Engineering Manager, Parker Hannifin. “As a founding member of MESA, Parker views Nuvation’s adoption of MESA standards and their ongoing involvement as an important step in simplifying the integration of Nuvation BMS into energy storage systems.”

The MESA (Modular Energy Storage Architecture) Alliance is a California-based non-profit organization that was created to develop shared open standards and communication protocols for energy storage systems. Its work includes close collaboration with related groups including the SunSpec Alliance and the Electric Power Research Institute. MESA members include many of the energy storage industry’s leading utilities, ESS developers, battery manufacturers, energy management companies, and power conversion system (PCS) manufacturers. The goals of this industry-driven effort towards standardization include giving electrical utilities more choice by enabling multi-vendor, component-based energy storage systems.

“Nuvation’s MESA-conformant BMS can be integrated with 1Energy’s Intelligent Controller product with minimal effort and expense, which makes it an excellent battery management solution for energy storage systems that are being managed by our software,” said Andrew Miller, VP of Engineering, 1Energy Systems. “Nuvation’s contributions to MESA over the past year have accelerated the energy storage industry’s progress towards open standards for ESS design and ensured that battery management systems are well covered by the standard.”

Nuvation Engineering joined MESA in February, 2015 and is currently collaborating with other MESA members to develop the Draft 4 specification. Draft 4 will include new battery models that expose significant additional measurement and performance data for lithium-ion batteries. In addition, it will include definitions for commonly used terms such as “State of Health” and “State of Charge,” which can often be a source of confusion within the energy storage industry.
