Reduce costs, improve quality and enhance efficiency

Zestec will not only fund PV solutions via their PPA but can also fund Battery Energy Storage Systems (BESS) on behalf of our clients.

Storage is a critical aspect of Energy Transition; it can support businesses by leveraging their on-site generation but also potentially by leveraging available on-site space to benefit from proximity to the network and market volatility.

If you are looking to install, or have already installed, on-site solar PV generation, then energy storage can be a great solution to reduce costs further, improve power quality, and enhance system efficiency. Additionally, if your business is in an area constrained by availability, there are other innovative ways that BESS can be deployed.

The commercial energy storage opportunity

Battery Energy Storage systems are designed to leverage energy generation and reduce energy costs, whether that be from on-site generation; for example your solar PV system or capacity needs of the grid. Integrated into a Solar PV system, Zestec can use energy storage to improve the quality of your power supply by using a battery to regulate the voltage and frequency.

With an understanding of the needs and possibilities for your business; our experts will design the integration of your solution, taking into account your load profile, energy consumption patterns, renewable generation capacity and available space on your site.
