Evaluating the capabilities of behind the meter storage systems

Evaluating the capabilities of behind the meter storage systems

Arizona’s sunshine is legendary, but so are the rising electricity costs that come with keeping your home cool during scorching summers. What if you could take control of your energy use and turn that sunshine into significant savings? With behind-the-meter photovoltaic energy storage systems (BTM PVESS), you can do exactly that.

In this guide we will explore the meaning of behind-the-meter. Its characteristics, challenges residents face in backup storage, and the capabilities of BTM PVESS

What is behind the meter?

Behind-the-Meter (BTM) Energy Storage refers to energy storage systems installed on the customer side of the utility meter, typically at residential or commercial properties. These systems act as personal energy banks, allowing users to store excess energy generated by sources like solar panels. This stored energy can be used when solar generation is low or during power outages, reducing reliance on the grid and potentially lowering electricity bills. By storing energy locally, BTM Energy Storage systems offer increased energy independence and resilience, making them an attractive option for homeowners and businesses seeking to manage their energy usage more efficiently.

Characteristics of BTM BESS

Behind-the-Meter Battery Energy Storage Systems (BESS) offer several unique features that make them stand out as a versatile and practical solution for residential energy needs.

1. Size and quantity:

The size and quantity of these systems can be tailored to fit individual requirements. Whether you have limited rooftop space or ample room for a larger installation, there are options available to suit your needs.

2. Siting and operation:

The siting and operation of BTM BESS are designed to be user-friendly and efficient. These systems can be installed in various locations around your property, including garages, basements, or outdoors, depending on your preferences and available space. Once installed, they can operate autonomously, optimizing their charging and discharging cycles to maximize energy efficiency and cost savings.

3. Visibility:

BTM BESS are designed with aesthetics in mind. They are often sleek and unobtrusive, blending seamlessly into your home’s design without compromising its visual appeal. This design feature ensures that your energy storage system not only provides practical benefits but also enhances the overall look of your property.

Challenges residents face in backup storage

Challenges homeowners face with backup storage highlight the importance of reliable energy solutions.

1. Heating and cooling loads:

Managing heating and cooling loads, especially during peak demand periods, can strain energy resources. BTM BESS offers a solution by providing stored energy precisely when demand is high, ensuring your home stays comfortable without overloading the grid.

2. Efficiency of equipment:

The efficiency of equipment is paramount for maximizing the benefits of backup storage. High-quality components and regular maintenance are essential to ensure smooth operation and optimal energy savings.

3. Roof area constraints:

Limited roof space for solar panels can be a challenge, but careful planning and sizing can help homeowners make the most of what they have. Properly designed systems can still provide significant benefits, even with constrained space.

4. Power-interruptions conditions:

Power interruptions are inevitable, but having backup power from BTM BESS can be a lifesaver. These systems ensure that you have electricity when you need it most, whether due to grid failures, maintenance, or other issues.

5. Grid reliability:

Dependence on the grid for power can be risky, especially in areas with unreliable infrastructure. BTM BESS provides a more stable energy supply, reducing vulnerability to grid issues and ensuring a reliable power source.

6. Rising climate and wildfire impacts:

With climate change and wildfires becoming more frequent and severe, having a reliable energy source is crucial. BTM BESS can help homeowners weather these challenges more resiliently, providing a reliable source of energy even during challenging environmental conditions.

Capabilities of BTM PVESS

Behind-the-meter photovoltaic energy storage systems (BTM PVESS) are innovative solutions that integrate solar power generation with energy storage capabilities. This integration allows residents to produce and store their own electricity, reducing their dependence on the grid and ultimately lowering their electricity bills. Let’s delve deeper into the key capabilities of BTM PVESS:

1. Bill savings:

By harnessing solar power and storing excess energy during off-peak hours when electricity rates are low, residents can use this stored energy during peak hours when rates are high. This strategy helps residents reduce their overall electricity costs, leading to substantial bill savings over time.

2. Reliability and resiliency:

BTM PVESS enhances the reliability and resiliency of the electricity supply. During power outages or grid failures, these systems can seamlessly switch to backup power mode, ensuring that essential services like lighting, refrigeration, and communication remain operational.

3. Power quality:

BTM PVESS contribute to improving power quality by providing a stable source of electricity. This stability helps reduce voltage fluctuations and enhances the overall reliability of the electrical system, ensuring consistent and reliable power supply.

4. Ancillary services:

These systems can also provide ancillary services to the grid, such as frequency regulation and voltage support. By actively participating in grid operations, BTM PVESS contribute to improving the stability and efficiency of the grid, benefiting all electricity consumers.

5. Transmission and distribution upgrade deferral:

BTM PVESS can help defer the need for costly upgrades to transmission and distribution infrastructure. By reducing peak demand and offering localized power generation and storage, these systems help utilities avoid significant investments in expanding their infrastructure, thereby saving costs and improving efficiency.

BTM PVESS offers a range of capabilities that not only benefit individual residents but also contribute to the overall efficiency, reliability, and sustainability of the electricity grid. As these systems become more widespread, they will play a crucial role in shaping the future of energy management and consumption.
