Solutions are sized from 69kWh (18kW of bi-directional inverters), 138kWh (36kW of bi-directional inverters) and 207kWh (54kW of bi-directional inverters.) System equipment is housed in an environmentally controlled shelter to protect components from Colorado’s varying weather patterns. The battery is charged and discharged through a grid connection while energy is stored in and distributed from a Lithium-Ion battery bank.
This NRI Energy Storage System reduces overall daily peak demand by supplementing the load with energy stored within the battery. Although there is no localized generation available, NRI's intelligent SC-100 controller adjusts to fluctuating grid costs and charges the battery when prices are at their lowest. in addition, this "added" consumption used for recharge is offset by the methods mentioned above while peak shaving and/or demand flattening reduce overall tariffs for the facility.
As a result NRI was approached… our team then developed a well rounded microgrid consisting of 30 independent solar arrays, back-up generators, and battery energy storage in an environmentally controlled shelter to delivered cost-savings, energy independence, and reliability to the residents of Naushon Island. Other features of NRI’s solution include multiple layers of protection (no system shutdown should a component need maintenance and/or replacement,) direct integration into the island’s existing power grid, and a 4,800 Amp-hour, industrial battery system. The battery holds excess solar power for when energy is needed while our system controller monitors all system functions/equipment such as the generators, batteries, fuel tank, environmentals, system faults and alarms. Paired SCADA also allows for insight into microgrid’s operation.
Northern Reliability provided PSE&G 35 Solar-powered obstruction lighting systems, each integrating a 1530-watt solar array with a deep-cycle battery bank which stores the harvested energy to power the safety beacons during periods of low solar availability. Our team custom designed tower mounting solutions for each of the three different styles of utility towers used on the PSE&G project. The system’s battery bank and controls are housed in a custom-designed SOLS environmental enclosure, located at the base of each tower. As self-contained, stand alone power sources, Northern Reliability’s SOLS systems provide cost savings to PSE&G by eliminating the need to install a second, low-voltage distribution line to power the FAA required safety beacons along the transmission line route. Obstruction safety lighting also eliminates the need to continually paint the towers for increased visibility, reducing PSE&G’s ongoing maintenance costs.
The system was designed to endure long periods of time between servicing and/or refueling. To protect the equipment during Edmonton’s severe winter, NRI’s team developed a weather resistant enclosure to house the generator and ensure back-up power during the winter months.
NRI’s team installed a 34 Kilowatt hour battery bank, upgraded the floor supports, replaced the outdated photovoltaics and introduced a new standing-seam aluminum roof. Altogether, Northern Reliability’s solution allowed the Block Island outpost to comfortably remain off the grid while taking care of all septic/water pump demands, kitchen appliances, lights and communications equipment.
To accomplish this in the harsh climate of the southern mountains in Nevada, Northern Reliability provided heavily insulated, heated and actively ventilated battery cabinets. These design elements environmentally protected the batteries from extreme temperatures while maintaining a healthy life-span and capacity. In addition, Northern Reliability designed a custom mounting frame with adjustable legs and articulating feet so that the systems could easily be deployed on uneven, rocky ground.
