Innovation
The innovation of easy installation serves to reduce the complexity of a monitoring system able to collect all data from inverters by implementing the inverter protocol and thus provide a high depth of data. All inverter-specific settings are done automatically to simplify the installation process. Only basic knowledge is required to install the monitoring. The time required at the plant site is reduced to the cabling. The whole costs of monitoring are also thereby reduced.
Customer Benefits
Installers can offer and install a monitoring system with minimum effort. An easy and quick installation reduces the costs of installing a monitoring system and makes a PV plant even more profitable.
Problem Solved The Dynamic Power Resource manages fluctuations in supply versus demand and automatically responds to discrepancies to ensure utilities can supply consistent, stable power on demand.
Noteworthy
The dry cell battery storage technology in the Dynamic Power Resource has no siting or transportation restrictions, and the entire system works in conjunction with existing resources, requiring no expensive infrastructure overhaul. The technology is also scalable in terms of both power rating and storage capacity to meet diverse customer needs.
Innovation
Xtreme Power Dynamic Power Resource
The Dynamic Power Resource is an energy storage and power management system designed to help utilities, independent power producers and renewable energy project developers more easily integrate renewable energy onto the grid.
Challenge
Utilities and independent power producers (IPPs) are seeking ways to efficiently and affordably integrate solar energy, as well as a means to effectively manage existing resources. Energy storage and power management systems are crucial in capturing clean energy for integration and deployment. However, energy storage has historically been expensive and difficult to merge with existing transmission and distribution infrastructure.
A wide variety of energy storage options are currently available, including flywheels, pumped hydro, and numerous battery compositions. However, the majority of providers offer only a storage component, meaning the technologies are often restricted to providing only off- peak to on-peak applications. Conversely, Xtreme Power’s Dynamic Power Resource is a comprehensive system, providing storage capabilities as well as highly responsive power electronics and system controls. In offering a fully automated, multi-functional technology, Xtreme Power has become the optimal choice for utilities, IPPs and renewable energy integrators nationwide.
Dynamic Power Resources also prove advantageous over competing technologies in several key areas:
Safety and Siting
Competing energy storage technologies each face challenges in terms of permitting and siting. Methods such as pumped hydro are limited by the specific geographies required for use, and traditional battery-based storage methods present safety concerns due to their potentially hazardous chemical compositions (lead-acid, sodium-sulfur, lithium-ion, etc.).
In contrast, Xtreme Power’s non-toxic PowerCells are a dry cell technology,

meaning they contain no gels, liquids or pastes. The dry cell batteries are made of ballistic-grade fiber and alloybased bi-polar plates, enabling a low internal resistance and ambient temperatures during charge and discharge periods. PowerCells can be safely stacked and housed in substations or on site of energy installations. PowerCells are also produced with 95% recyclable materials and are collected by Xtreme Power at end-of-life to create new batteries.
Performance PowerCells are a hybrid technology, combining the power capabilities of capacitors and energy density of batteries. As previously noted, the PowerCells have a very low internal resistance, enabling them to charge and discharge rapidly for an industry-leading efficiency of approximately 98 percent.
Size
While most providers take a one size fits all approach to storage, Xtreme Power can configure power rating (measured in megawatts) and storage capabilities (measured in megawatt-hours) independently, allowing the company to customize each Dynamic Power Resource to the needs of a particular customer. Additionally, the uniform characteristics of PowerCells enable Xtreme Power to configure immense systems in parallel, with 24,000 PowerCells racked together in the companys largest project to date.
Customer Benefits Xtreme Powers Dynamic Power Resource is a cost effective technology, both in terms of upfront capital and long term expenditure. The systems high efficiency permits a lifecycle/cost ratio superior to those of competing storage technologies.
Additionally, the Dynamic Power Resource works in conjunction with existing utility hardware and software and operates automatically, meaning it can be implemented without expensive infrastructure overhaul.
