Product Overview
Overview
EcoJoule Energy provides power management products and software to companies interested in energy quality and reliability for their customers as renewable energies are adopted, proving that the current grid system isn't fully equipped to handle the ensuing challenges.
The company has developed two main products:
EcoVAR - Voltage Regulator:
The EcoVAR is a Low Voltage STATic COMpensator (STATCOM) that helps utilities manage the voltage on Low Voltage Networks.
Mounted on low-voltage poles, this device uses advanced technology to ensure the electricity flowing through the grid remains stable - addressing issues like sudden drops or spikes in voltage, and even balances the phases of electricity
EcoSTORE - Battery Energy Storage System:
The EcoStore is a 10kW AC coupled smart battery inverter that can intelligently charge and discharge batteries to optimally manage electrical energy usage.
Similar to a communal battery that not only stores energy but also manages the distributed power quality. EcoSTORE combines the capabilities of EcoVAR with an advanced Battery Energy Storage System (BESS). It offers a smart solution for regions where the local grid is reaching its capacity, providing a reliable and sustainable alternative.
The latest Ecojoule products now come with a patented feature. This feature allows them to shift active power between different phases, enhancing the overall quality and reliability of the power grids.
Business Model
EcoJoule sells their products directly to the distribution system operators per unit and per project basis.
Technology Innovations
Pole-mounted Low Voltage STATCOMs: While various voltage regulators populate the market, only a select few offer pole-mounted, continuous-output STATCOMs tailored for the low voltage grid.
EcoSTORE's Distinctiveness: While pole-mounted energy storage systems are offered by a handful, Ecojoule's EcoSTORE is in a league of its own. Its unique approach uses power electronics to stabilize the grid, bypassing the need to constantly discharge batteries. This not only extends the battery lifespan but also bolsters its cost-effectiveness and sustainability.
Applications
Historically, the low voltage grid-edge was a stable, often overlooked segment of the electricity supply chain. But with the rise of rooftop PVs, EVs, and heat pumps, power quality has deteriorated:
- Voltage Fluctuations: DERs introduce sags and swells that frequently breach regulated voltage limits, affecting grid stability.
- Phase Imbalances: As varied loads connect to different phases, significant imbalances arise, shortening the lifespan of secondary substation transformers.
- Line Capacity Concerns: Many low-carbon technologies can triple a household's electricity consumption. This influx poses challenges for system operators approving DER installations, leading to potential delays.
Ecojoule's mission is to address these issues using non-wire alternatives, harnessing advanced power electronics to enhance grid reliability without the need for additional wiring.
