In order to synchronize generation assets for electrical grid operation, the AC frequency must be held within tight tolerance bounds. Storage helps to correct short-term changes in electricity use that might affect the stability of the power grid by matching generation and load and by adjusting generation output to maintain the desired frequency. Fleet aggregators of so called "virtual power plants" can earn revenue by providing electricity to the grid, on demand within milliseconds and can still offer home owners battery backup functionality whenever the grid is down.
Eguana's products are the ideal solution for project developers bidding into grid service markets. Eguana's patented PCS reacts in milliseconds to the grid control signal, and the open control communication protocol of all Eguana products gives fleet aggregators full flexibility to seamlessly integrate the storage system into their existing network.
Demand Charge Management
Large users of electricity often bear disproportionately high energy costs because they not only pay for the energy they actually use, but they are also required to pay for the right to have energy capacity available to them (whether or not they are using that capacity) at all times. This billing structure is called a “demand charge.” Utility regulators across the United States and in other countries are increasingly allowing – and even encouraging – utilities to impose demand charges on large electricity users as a way to reduce peak demand, which is becoming a growing burden on the electric grid. For many commercial customers, demand charges can comprise 30% to 70% of their electric bills. By some estimates, between 10% and 20% of all electricity costs in the U.S. are attributable to peak demand.
Energy storage systems can help with shaving the demand peaks, which can significantly reduce the electricity bill of commercial and industrial customers.
Eguana's three phase power control solution are the ideal fit for small commercial and light industrial applications.
With a power rating of 15kW, Eguana's power control solutions are ideally suited for demand charge management applications, in which modular building blocks are essential to provide the required redundancy in case of system failures.
The low voltage input of Eguana’s three phase power electronics allows the project developers to right size the battery capacity to match the customer’s capacity and budget requirements.
