Why Storage? Part 4: Demand Charge Reduction

by Chris Rigatti on December 15, 2016 at 3:17 PM

For our last post in this series, we'll look at peak demand charge management.  

While demand charges have been used for commercial and industrial customers for some time, they’re relatively new to residential customers.

Most residential energy bills in the US today include a fixed charge to cover the cost of maintaining the grid infrastructure, which is the same for every customer, and a variable charge based on the amount of energy (kilowatt hours, or kWh) used in a month which covers the cost of generating that energy at a power plant.   With peak demand charges, the fixed charge is replaced by a variable charge based on the maximum power (in kilowatts, or kW) that a customer uses in the month at any time. While this might seem like a penalty, it tends to be a good thing for the electricity system as a whole, because utilities need to invest in infrastructure to handle that peak power demand, even if it only occurs for a few minutes each month.  Peak demand charges are a way of passing the costs along to the customers that actually incur them.


Why Storage? Part 1: Solar Self-Consumption

A solar system for my home is already a major investment… why would I want to add energy storage to that?

A very common (and valid) question we hear from homeowners… what in the world can I do with batteries in my home that justify the extra hassle and expense of them?  On the surface, most people instantly think of playing the energy arbitrage game: buy energy to charge my batteries when power is cheap and discharge when my utility is charging me a much higher price.


Why Our Saltwater Batteries are Named After Aspen Trees

You know about Aquion because of our unique Aqueous Hybrid Ion technology.

Since this chemistry is so central to who we are, it became our company name: “Aquion” is a portmanteau of “aqueous” and “ion.” In the solar energy storage industry, we’re the company with the saltwater batteries.

So, you may be wondering... if our batteries are full of saltwater, then why are they named after a tree?


Project Spotlight: Solar Microgrid on the Protected Kona Coast of Hawaii

Ever wondered what it would be like to have your own personal resort on the beaches of Hawaii? Well, for one particular family, it's pretty great -- but it comes with some surprising challenges.

Located on the west coast of Hawaii's Big Island, the family's estate has a variety of amenities, from a swimming pool and tennis court to an ocean view. It's also completely green, producing nearly 100% of its energy from solar. The property sits on top of a lava flow, in the middle of a nature preserve, and directly on the beach. It is warm, secluded, and absolutely beautiful.


Living Off the Grid in Northern California

Redwood Gate Ranch is a unique and beautiful mountain residence that overlooks the forests of Jenner, California. The property’s stunning views and remote peacefulness came at the price of being outside the power utility’s service area. Living off the grid meant that access to reliable electricity posed a real challenge to the property owners.
