PowerBlock

PowerBlock
Reliable generation that's always on

PowerBlock

mobile powerblock
PowerBlock is a power system for standby generation and participation in utility or RTO/ISO markets, incorporating proprietary switchgear, controls and monitoring software to result in a fully-integrated solution for customers’ energy needs. Moreover, the PowerBlock Tier 4 Final Genset is an ultra-clean modular diesel generation system that is flexible in capacity and has no federal run-time limitations or post-installation emission test requirements. With seamless paralleling, 24/7 energy system monitoring and built-in redundancy, PowerBlock is reliable, resilient, and scalable to any and all power demands.

PowerBlockG

The PowerBlockG operates on a variety of natural gas fuels and liquid propane, utilizing ultra-clean generators to simultaneously provide power while leaving an energy footprint smaller than that of traditional systems. Combined with bi-fuel capabilities, allowing it to switch fuels on the fly under load, the PowerBlockG can increase the run times of on-site fuel capacity and substantially improve emergency preparedness.

PowerBlock3®

PowerBlock3 is PowerSecure’s unprecedented stackable, modular power system, providing more energy capacity and transportation ease in a smaller footprint than any other system available. While utilizing all the same PowerBlock technologies, PowerBlock3 is reconfigured for maximum power density. Pre-assembled, pre-wired and pre-tested in ISO containers, it is ready for installation anywhere.

PowerBlock Mobile

The PowerBlockM generator is a modular, movable solution that comes equipped with EPA-certified Tier 4 interim and final engines, as well as on-board diesel fuel and diesel exhaust fluid tanks that provide 16 hours of capacity. The PowerBlockM provides customers with a reliable source of power at any time and any location and can even be utilized to assist neighboring communities during emergencies.

Inverters

DOUBLE-CONVERSION-INVERTER
Convert and monitor your power flow

Inverters

Inverter
Inverters are integrated into all PowerSecure microgrids in order to accurately regulate the power flow to and from site equipment. Double conversion inverters convert between alternating currents (AC) and direct currents (DC), while photovoltaic DC inverters convert and monitor PV system power flow into a microgrid. PowerSecure microgrids only utilize inverters from leading industry providers to maximize efficiency, flexibility, and lifetime for the various systems in which they are implemented.

Power Distribution Engineering & Design

PowerSecure specializes in bespoke energy solutions — complete with the engineering, design, financing, planning and procurement needed to bring your emergency backup power or microgrid system online.

Whether using conventional energy sources, renewable power or a combination of both, our end-to-end power distribution engineering solutions also come with post-installation monitoring and maintenance to help ensure your organization can continue powering its operations around the clock — regardless of grid conditions.

Technology

PowerSecure is committed to the reliability of our power distribution engineering. Our dedication to excellence begins with high-performance natural gas engines and Volvo diesel engines that meet or exceed EPA Tier 4 Final requirements, the cleanest diesel engines available. We then integrate engines (either diesel or natural gas options) into our PowerBlock® with a generator, controls, switchgear, integral fuel and DEF tanks, and a sound-attenuating enclosure. Each PowerBlock can house one to six generators rated 625kW. The PowerBlock can be installed as a standby generator or as the centerpiece of an advanced microgrid that can include PV, fuel cells, battery storage and legacy assets such as turbines. Additional PowerBlock solutions include the PowerBlock mobile unit and our modular PowerBlock3®.

Our team of experts can also deliver facility-scale energy-efficient engineering and design. We offer end-to-end development, construction and implementation of your solutions and can integrate the energy efficiency projects into your microgrid system.
