Battery vs Backup Generator

Battery vs Backup Generator

There is a lot of hype regarding batteries. Much of it is well deserved. However, this hype could put your operations at risk when the discussion turns to resiliency and backup.

This eBook goes into detail comparing batteries with and without solar to natural gas backup generation. In this book you will learn:

• A simple metaphor that provides an easy-to-understand conceptual framework.
• Batteries are not economically justified for backup.
• Solar with battery is better than batteries alone, but still not cost effective for backup.
• How to determine how much backup power you need.
• The cost comparison between backup generators and batteries.
• How the variability of solar impacts resiliency design of batteries.

Exergy’s software and operations are invisible to our customers; they never know whether they are using renewable electrons from the grid or from the on-site generator.

Educational Videos

Educational Videos

Episode 1: How To Be Green, Resilient And Save Money: The Basics. In our first video, we explain how underinvestment in the Grid has led to a steep decline in reliability. For Always-On organizations where energy is mission critical, going down is not an option. We discuss installing batteries and generators for backup, and delve into the benefits and drawbacks of each. We end the webinar explaining how organizations can be 100% green, 100% resilient to power outages, and save money on their electricity bill by working with Exergy. (For a copy of the slides, please contact us.)

Episode 2: How To Be Green, Resilient And Save Money: How To Get A Free Backup Generator. Our second video describes the cost of downtime to Always-On organizations, and how Exergy will provide you with a free backup generator to make you 100% resilient to blackouts. We use the generator to keep your operations running, reduce your peak load contribution, and generate ancillary revenues from participation in programs such as demand response and frequency regulation. (For a copy of the slides, please contact us.)

Episode 3: How To Be Green, Resilient And Save Money: Battery vs. Backup Generator. Video three explains how a battery is like a bucket of water when you are trying to put out a fire, and a generator is a firehose. We dive into the numbers and calculate how many buckets (batteries) you need to ensure your organization’s uptime. We even analyze the benefits and drawbacks of adding onsite solar to ensure a minimum uptime of 99%. We conclude with our assessment of when to use batteries vs. backup generators. (For a copy of the slides, please contact us.)

Episode 4: How To Be Green, Resilient And Save Money: Free Battery. In video four, we examine what possible functions a battery can service in addition to backup. These include energy arbitrage, frequency regulation, and voltage support, among others.  But which are really feasible? How much do batteries cost? And if you use a battery for several functions, will that limit its ability to serve as backup? We also look at combining solar with batteries to see how they might work together. (For a copy of the slides, please contact us.)

Episode 5: How To Be Green, Resilient And Save Money: Is Behind the Meter Solar A Good Idea? We delve into the benefits and drawbacks on behind-the-meter (onsite) solar in video five, examining the costs and comparing it to utility-scale solar as an alternative.  (For a copy of the slides, please contact us.)

Episode 6: How To Be Green, Resilient And Save Money: Understanding your Bill. Ever taken a look at your electricity bill and wondered what some of the line items were? In video 6 we investigate the anatomy of an electric bill to understand what our costs, and how to minimize our future bills. We explain terms like peak load contribution, peak shaving, and demand response. Finally, we ask how your organization can save money. (For a copy of the slides, please contact us.)

Episode 7: How To Be Green, Resilient And Save Money: Rethinking Energy Efficiency Investing. We are told that efficiency is always good. In video 7, we dare to ask the question: when is it better to forego efficiency? When energy is the enable that powers growth and productivity! We investigate this concept and put efficiency and productivity into perspective. (For a copy of the slides, please contact us.)

Special Webinar – Diesel corrosion might kill you! (It will kill your backup generator)  Nearly all diesel fuel today has some biodiesel mixed in, which can lead to unexpected system corrosion and failure of your engine or backup generator. Learn more here, and how to prevent this from occurring to your diesel system.
