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 2: Backup Power & Islanding

Power outages are surprisingly common for homeowners in the US.

This is especially true in densely populated states like California, Texas and New York.  For instance, California alone had over 400 outages in 2015, and nationwide over 13 million people were affected by blackouts lasting an hour or more.

Residential Energy Storage in Australia: Maximizing Solar Self-Consumption

by Chris Rigatti on October 19, 2016 at 5:22 PM

Australia is one of the world’s leading markets for solar and energy storage.

The country’s high energy prices, abundant sun, and decreasing feed-in-tariffs (money paid or credit to consumers for excess solar power fed back into the grid) have led more and more consumers to consider batteries.

Lead Acid Battery Recycling and Clean Energy in the Developing World

Clean Energy for the Developing World 

As the cost of solar panels and batteries continues to fall, the potential for renewable energy to raise the standard of living in the developing world is becoming a reality. For those of us with air conditioning and Pokemon Go, it may be hard to imagine that nearly one quarter of the world’s population lives without access to electricity.

Developing a centralized electricity grid is a massive undertaking that may never be economically feasible for many developing nations. But solar and energy storage technologies are enabling the creation of distributed renewable energy systems, giving power to people in remote areas where it was previously not possible.
