EnSync Energy jumps into residential solar+storage, includes ‘peer-to-peer’ energy exchange

Ensync energy systems

EnSync Energy Systems, a leader in distributed energy resources (DERs) and business models for commercial and industrial (C&I) buildings and microgrid installations, is launching a new integrated system for residential customers. The EnSync Home Energy System combines solar, energy storage, power electronics and an Internet of Energy control platform that delivers state-of-the-art functionality and modularity, with industry benchmark economics, safety and system efficiency. This could be the solution the multifamily sector has been waiting for.

“The current state of solar plus energy storage systems for the home is in the dark ages,” said Brad Hansen, president and CEO of EnSync Energy Systems. “Most are significantly underpowered and cannot support the entire home if the grid electricity is out, or they have issues disconnecting and reconnecting to the grid during an outage. If the home is off-grid, many cannot reliably perform if high inrush currents are created by the start-up of appliances like refrigerators or air conditioners.”

Hansen is also wary of the saftey of most home solar + storage systems.

“Many systems use lithium-ion batteries that are repackaged EV car batteries,” he continues. “Some of these battery chemistries raise thermal stability concerns when utilized in a home energy storage application. Systems on the market today are typically characterized by a mix and match of components that may or may not integrate well together and lack the modularity required to customize the optimum system for each individual home.”

The EnSync Home Energy System addresses these weaknesses and includes a residential-scale version of the company’s modular Matrix Energy Management system, safe and thermally resilient lithium-ion batteries and its DER Flex Internet of Energy solution — all of which were designed to work together at the outset.

Peer to Peer innovation

“Additionally, we’re bringing a phenomenal differentiator to the market with our True Peer-to-Peer energy exchange technology,” Hansen says. “True Peer-to-Peer enables individual residential units in a property to be linked into a network behind the utility meter to provide highly efficient, direct energy exchange between units. This is a major advantage for property developers, property managers and homeowners’ associations, providing the benefit of highly efficient and economical transfer of excess energy from any given residence on the DC-Link to any other residence in the network with excess demand. With True Peer-to-Peer, the entire property experiences a dramatic increase in the efficiency of the deployed renewable generation across the community. The payoff is a reduced consumption of grid electricity and significantly improved solar energy economics for everyone in the network.”

The sharing of electricity between interconnected residences on a True Peer-to-Peer energy exchange network prioritizes the use of solar generated or stored electricity ahead of that from the utility grid for any residence in the network. The network can also be configured as “non-export,” meaning no excess generation for any unit goes back to the utility grid. This capability is becoming more critical as several states and jurisdictions prohibit or economically penalize energy export.

Additionally, many utilities are in the early stages of implementing time-of-day electricity rates and are already levying increasing demand charges on customers. The evolving rate structures and impact of resident vacancy rates, vacation schedules and time-of-day load profiles frequently make deploying solar generation uneconomical for large portions of a property development. Virtual net-metering and virtual peer-to-peer programs are fraught with excessive complexity and administrative overhead. True Peer-to-Peer changes the game by incorporating each residence in the network onto a simple DC-Link, where the excess generation or generation deficit impacts of any given unit can be aggregated across a larger population of units in the network.

“The future of the electricity market will be individual homes and building owners operating in a ‘spot market’ for the buying and selling of electricity across a network. At EnSync, we have enabled this future to exist today with our innovative products and services,” said Hansen. “Our mission for the company is simple: the democratization of energy through innovative and economic energy systems. Homeowners and property owners that install our products today do so with the confidence that as the market for energy continues to be radically changed, they are not only prepared for it, but can capitalize on it and profit from it.”

EnSync will initially target the multi-residential property market for its solution, then broaden its market presence. At the time of announcement, the company has already built a sizable order backlog for the EnSync Home Energy System, including the approximately 150-unit Keahumoa Place property in Oahu, Hawaii, announced on May 9, which will utilize True Peer-to-Peer energy exchange.

The EnSync Home Energy System includes high-efficiency “LFP” lithium-ion batteries, a Matrix Energy Management system with 9-kilowatt alternating current (AC) output capacity, modular energy storage capacity of 9-kilowatt hour increments, modular direct current (DC)-DC converters for photovoltaic and energy storage and the DER Flex Internet of Energy control platform, which enables a home to access the same DER Flex cloud-based computing platform utilized by EnSync for connectivity between the asset owner, grid network and real-time market data for its C&I customers.

State funding paves way for solar plus storage system at New York college campus

A solar energy and battery storage system was completed on The State University of New York at New Paltz campus. The battery storage unit will be used at times of high electric demand and during emergencies or power outages to support the college’s designated emergency shelter for the campus and community at the college’s Elting Gymnasium. The project supports N.Y. Governor Andrew Cuomo’s initiative to increase the transmission of clean and renewable energy to meet an energy storage target of 1,500 megawatts in New York State by 2025.

“New Yorkers know all too well the devastating impact of climate change, and we have taken bold action to slow its effects and invest in the energies of tomorrow,” Governor Cuomo said. “This renewable energy and storage project will greatly enhance the college’s resiliency in the event of an emergency while also reducing the state’s carbon footprint and saving taxpayer dollars year-round.”

Lieutenant Governor Kathy Hochul, who was present at the ribbon-cutting event, said, “This innovative project advances New York’s Reforming the Energy Vision strategy to build a statewide energy system that is clean, resilient and affordable for all New Yorkers. Thanks to a significant investment from New York State, this project will provide great benefits to both SUNY New Paltz and the state’s electric grid.”

Richard Kauffman, Chairman of Energy and Finance, Office of Governor Cuomo said, “Energy storage, especially when paired with renewable energy sources, makes up the building blocks of the Governor’s ambitious energy goals for the state. This partnership of state government entities will provide the road map to success for these rapidly emerging technologies.”

From planned research on this system, New York State utilities will be able to optimize the amount of renewable energy utilized on the state’s power grid, supporting the Governor’s goal to reduce greenhouse gas emissions 40 percent by 2030.

The $1.37 million project will install solar panels for the 217-kilowatt project on the gym’s roof and on the roof of the nearby Sojourner Truth Library to support the battery storage system. This will allow the college to utilize stored solar power during emergencies and times of peak energy demand. NYPA implemented the renewable energy and resiliency upgrades.

More than $580,000 in funding for the project from Governor Cuomo’s BuildSmart NY program, a comprehensive statewide initiative to increase energy efficiency in public buildings. $272,000 in additional funding from the New York State Energy Research and Development Authority for the solar portion of this project through NY-Sun, Governor Cuomo’s initiative to advance the scale-up of solar and move the state closer to having a sustainable, self-sufficient solar industry. An additional $189,000 came from Central Hudson Gas & Electric, the college’s local utility. The additional costs for the project were financed by NYPA and will be repaid by the college.

This project was led by NYPA in partnership with SUNY New Paltz. NYPA, NYSERDA and the Electric Power Research Institute are utilizing this project to research additional technical and economic benefits of the project. The research is being done through EPRI’s Integrated Grid initiative.

EnSync, J. Walter Cameron Center sell 20-year solar-plus-storage PPA

Ensync energy systems

EnSync announced the sale of a 20-year power purchase agreement (PPA) it arranged on behalf of J. Walter Cameron Center (JWCC) to an undisclosed investor. The PPA will bring the nonprofit incubator space nearly half a million dollars in savings during the terms of the agreement.

EnSync Energy’s project engineers consulted with JWCC to size the non-exporting system to meet the center’s current operational needs while allowing room for expansion. The resulting solar plus storage project encompasses a 148-kW photovoltaic (PV) installation and EnSync Energy’s DER SuperModule—244 kWh of energy storage supported by EnSync Energy’s Matrix Energy Management System and DER Flex technologies. The alternating current, PV-only system directly serves the buildings’ loads, and a direct current system connected to the SuperModule stores energy for off-peak solar hours and for demand charge mitigation.

JWCC provides over 43,000 square feet of office space across six individual buildings to 16 resident agencies, including The American Cancer Society – Hawaii Pacific, The American Red Cross and The Maui Chamber of Commerce. The center also provides program space and support resources to over 250 community groups that together serve 30,000 Mauiresidents. Beyond cost reductions from the lower PPA rate, JWCC will benefit from demand charge mitigation services, which will decrease the center’s utility bills by relying on energy storage to manage high demand charges.
Construction will commence in the coming months.
