BESS + Solar self-consumption hybridization
Enhance the value of on-site renewable energy production
The Battery Energy Storage System (BESS) + Solar self-consumption hybridization consists in combining a battery energy storage system with a solar photovoltaic installation to maximize the use of renewable energy produced on site.Solar energy, captured during sunny hours, is used directly to meet local energy needs, reducing dependence on electricity grids. Excess energy not consumed is stored in the BESS for later use, particularly during periods of insufficient solar production (at night or in bad weather). In this context, it is possible to oversize the solar installation to produce more energy than is immediately required, thus enabling greater storage capacity.
This oversizing increases the ratio of self-consumed energy, contributing to greater energy independence while optimizing costs and reducing losses due to grid injection. In winter or on days of low solar production, BESS can also be used to optimize the supply of electricity from the grid, or for grid regulation systems.
BESS + Solar grid-injection hybridization
Optimize the plant’s grid connection capacity
Battery Energy Storage System (BESS) + Solar Grid Injection Hybridization consists of combining a battery energy storage system with a solar photovoltaic installation to optimize the power plant’s connection to the grid by managing the energy injected into the grid. This type of system enables excess energy produced by solar panels to be stored, particularly during peak production hours (daytime), and redistributed when solar production is low (night-time or cloudy days).
Hybridization thus stabilizes energy injection into the grid, avoiding fluctuations due to intermittent solar production.
In addition, BESS can provide ancillary services to support the grid, such as frequency regulation, enabling agile management of the PV plants and access to new value levers.
BESS + EVCS hybridization
Boosting charging stations for electric vehicles
Hybridization between BESS (Battery Energy Storage System) and EVCS (Electric Vehicle Charging Infrastructure) combines a battery storage system with an electric charging infrastructure.
For the operator, this means rapid deployment of high-power stations with low-voltage connections. For end-users, it guarantees fast recharging even during periods of high demand. Intermediate energy storage also ensures that charging costs are kept under control by the operator, by reducing the impact of fluctuations in network tariffs.
This optimized energy management makes the stations scalable and resilient to variations in consumption (peak hours, etc.), a resilience reinforced by the integration of on-site solar panels.
Battery stand alone
Reinforcing energy autonomy without renewable energies
Stand-alone battery energy storage (BESS) consists in storing electricity from the power grid without resorting to alternative energies. Operating independently of renewable sources, BESS optimizes management of the energy available on the grid.
Batteries are charged during periods of low demand, when electricity is more abundant and less expensive, and then discharged during periods of high demand (load shifting), helping to smooth out consumption peaks (peak shaving).
BESS can also enhance power grid stability by providing system services such as frequency regulation, where available.
Microgrid
Drive a decentralized microgrid for enhanced resilience
A Microgrid is a local energy system capable of operating independently or as a complement to a main power grid. It integrates several decentralized energy sources, notably Solar photovoltaic. To maximize efficiency and energy management, the Microgrid also uses a Battery Energy Storage System (BESS). This system stores the energy produced by the solar panels during periods of high production and low demand, then releases it during peaks in consumption or when production is insufficient.
In addition, the integration of electric vehicle charging stations (EVCS, for “Electric Vehicle Charging Infrastructure”) into the Microgrid promotes the deployment of electric mobility, by offering a sustainable and accessible recharging solution. Together, these elements enable optimized energy management, reduce dependence on fossil fuels, cut energy costs and contribute to a lower carbon footprint, while improving the resilience of the energy system to main grid disruptions.
The Microgrid thus created with BESS offers enhanced resilience by enabling local power supplies to be maintained, even in the event of failure of the main grid. It also optimizes the integration of renewable energies and electric vehicle charging stations, reducing energy costs and carbon footprint. GreenYellow offers the latest technologies in this field, thanks to its partnership with Schneider Electric.
