Leveling Up, Hierarchy of Battery System Designs 2.0

Classifying battery system designs Interested in understanding battery system project risk and how to assess it? Please join me in Las Vegas on December 7th for a 4-hour, PDH-eligible course at 2015 Renewable Energy World. In early 2014 I published a work-in-progress called the Hierarchy of Battery System Design. It was an attempt to codify […]

Financing Battery Systems, Part II

Tackling battery system commercialization I published a short post on LinkedIn about a structural challenge in renewable energy, specifically energy storage. In summary, advanced energy storage has been in development for decades now, yet we are still seeing non-economic deals and demonstration projects. I’ve written before about the information asymmetry in this industry and while […]

Information asymmetry in energy storage: implications for battery system costs

First published on LinkedIn on 03 April 2015 Energy storage costs March 2015 at Electroferocious looked at information asymmetry in energy storage markets as a mechanism that increases project costs and threatens grid reliability, resilience, and security. System costs It’s difficult to get real numbers about energy storage system costs, and yet that is just […]

A brief exploration of electricity costs

If you haven’t already, I invite you to play with the Battery System Pricing calculator. It allows you to determine the per kilowatt and per kilowatt-hour pricing of a system as well as a rough estimate of the cost of delivered electricity. Evaluating both power and energy pricing makes it easier to compare different battery […]

Pricing grid energy storage: power vs energy

Should energy storage costs be $/kWh or $/kW?

Pricing conventions for energy storage systems Recently, battery systems have been in the news and on the minds of many. Many in the media have whipped out calculators, but I decided to build one so anyone can compare pricing. The challenge, however, is finding credible information amongst all the hype. Much of the hype centers […]

[Presentation] What is a battery system?

Information about energy storage systems is a popular topic which is why I’ve devoted the month of April to getting back to basics. A few weeks ago I attended the RSA Conference so, in the interest of time, I turned a previous post discussing a few key concepts defining battery systems into a slide deck. […]

Title: What is a battery system?

What is a battery system?

Battery system basics Establishing a common terminology and a few key concepts about battery systems will be useful to the ongoing discussions of performance, security, risk, and design. To facilitate that, I explain two diagrams showing the elements of a battery system and a simple battery system architecture. Send to Kindle

Two Types of Grid-Scale Battery Systems

Two Types of Grid-scale Battery Systems

Battery System Classification Grid-scale battery systems can be broadly classified into two types: AC-side and DC-side battery systems. Addressing project needs for a particular battery system design, its performance and risk, and the associated techno-economic models which can be built comes down to examining their differences. Let’s settle on some basic concepts first by using […]
