The energy storage industry continues to gain momentum around the world as industries of all types are actively working to minimize their carbon footprints and increase profits. While most energy storage deployments are stationary solutions, grid operators and facility owners around the world are beginning to recognize the value that mobile systems can provide.

Utilities, independent power producers (IPPs), regional transmission organizations (RTOs) and industrial and commercial organizations can benefit from energy storage systems that are flexible, mobile and quick to deploy. A mobile energy storage system can provide much needed additional generation, peak shifting, and grid support services at short notice, for short time periods or seasonally. This course explores the growing need for mobile energy storage and shows how it can help:

  • provide backup power to critical facilities in storm prone areas
  • meet temporary additional power generation needs for large events
  • provide energy storage services at short notice.

Learning Outcomes

  • Review what mobile storage is and why you might want it
  • Identify what mobile storage can do for you
  • Review the differences between stationary storage and mobile storage
  • Identify the different types of storage that work with mobile
  • Discuss the major components of mobile storage solutions
  • Examine lessons learned and things to think about

What is Mobile Storage and Why You Might Want It

  • Mobile storage defined
  • Why you want mobile storage – what it can do
    • Mobile vehicle charging for events
    • Planned work outage reduction
    • Unplanned outage reduction/temporary restoration
    • Grid balancing until permanent fixes can be made
    • Quiet time for generator fed locations (temp or semi-temp)
    • Support for a de-rated circuit
    • Testing of a new facility or interconnection
    • Testing new equipment at voltage and current levels expected in service
    • Providing power to an emergency shelter in a disaster
    • Providing power to construction equipment that is electric
    • Providing roadside service to out of “gas” electric vehicles
    • Demonstrating electric vehicles to an audience (e.g. fleet owners, Uber drivers, etc.)
  • What types of technology work for mobile storage
    • Batteries
    • Flywheels
    • Super Capacitors

The Differences Between Mobile Storage and Stationary Storage

  • Need a “substation” that is mobile too
  • Need to be crash resistant
  • Need an islanded protection system
    • Sensors
    • Relays
    • Breakers
    • Monitoring equipment
  • Fire protection system needs to be stand alone and comprehensive to meet NFPA 855 and NHTSA requirements
  • Needs to be controlled locally and be able to be controlled in a secure fashion remotely

Major Components of a Mobile Solution

  • The energy storage mechanism
  • The DC collector system
  • The power conversion system (DC/AC or DC/DC)
  • The transformer
  • The connection to the rest of the world
  • The control system
  • The charging system
  • HVAC system
  • The protection system
  • Fire and safety systems
  • The mobility platform
  • The prime mover
  • Local controllers
  • Power Quality system
  • Communications system
  • Physical security
  • Cyber security

Things to Think about and Lessons Learned

  • Unlike stationary storage – mobile storage has a premium on mass per unit of energy
    • Road limits and vehicle limits mean that lighter/unit energy is better
    • Concentrated weight must be avoided to remain under axel load limits
  • Storage must be sized to the vehicle not the job
    • This limits the number of use cases it can be used for
    • It limits duration or capacity of the use case being fulfilled
  • Hazards need to be mitigated for several configurations
    • Travel
    • Out of service and away from any source of electricity
    • Out of service but house power is available
    • In service and stationary
    • In service, but only temporarily stationary (e.g. charging a bulldozer)
    • Fast charging
    • Charging
    • On display (e.g. providing car charging at a high level event)
  • Does the energy store have to be on the same platform as the balance of system?
  • If you have separate energy stores, can you connect them in parallel and them disconnect one for charging elsewhere – do you want to?
  • How much in the way of ancillary equipment is too much
  • Lessons learned from systems specified and completed or in construction

Final Thoughts and Questions

Online Delivery

We will be using Microsoft Teams to facilitate your participation in the upcoming event. You do not need to have an existing Teams account in order to participate in the broadcast – the course will play in your browser and you will have the option of using a microphone to speak with the room and ask questions, or type any questions in via the chat window and our on-site representative will relay your question to the instructor.

  • You will receive a meeting invitation will include a link to join the meeting.
  • Separate meeting invitations will be sent for the morning and afternoon sessions of the course.
    • You will need to join the appropriate meeting at the appropriate time.
  • If you are using a microphone, please ensure that it is muted until such time as you need to ask a question.
  • The remote meeting connection will be open approximately 30 minutes before the start of the course. We encourage you to connect as early as possible in case you experience any unforeseen problems.


Please Note: This event is being conducted entirely online. All attendees will connect and attend from their computer, one connection per purchase. For details please see our FAQ

If you are unable to attend at the scheduled date and time, we make recordings available to all registrants for three business days after the event
