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 […]

WP Title - Understanding Electricity Costs

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 […]

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 […]

Why battery system cyber-physical security matters

Battery system cyber-physical security matters Energy storage has been held up as a panacea for renewable energy and grid modernization woes. There is a widely held belief that the challenges with energy infrastructure and grid modernization disappear with the availability of affordable energy storage. Battery systems are the front-runners in the grid-scale energy storage race. […]

Energy storage and project finance presentation

Energy storage and project finance in Africa and the US Last month, I participated on a panel discussing the financing of cleantech deployments in Africa at the heavily attended US Commercial Service’s Discover Global Markets: Sustainable Solutions conference. There were a number of points of connection from my presentation (PDF) that the audience shared with […]

Revenues from power and battery state of charge

Last time, we considered the impact of battery SOC (state of charge) technology on the ability to provide reliable and actionable data for modeling future¬†energy revenues from a battery system. On the power axis, the same revenue and risk concerns must be considered. While there are cost impacts for both as well, those topics will […]

Energy revenue impacts of Battery State of Charge (SOC)

SOC, or State of Charge, of a battery system is a perpetually hot topic among technologists. The relevance of the SOC technology discussion is easy to understand in the automotive context, as it represents a fuel gauge that primarily is the concern of the end-user. For infrastructure, a battery is always “full”, regardless of the […]

Battery System Risk Management: Power, Efficiency, and Revenue

Battery technology risk Technology risk for energy storage projects is managed best by energy storage developers. There are also aspects of design and planning risk which should appropriately be allocated to us. We hold the necessary information and capability to ensure appropriate engineering and design, construction, commissioning, and operations & maintenance of our technologies. The […]
