Energy Storage System (ESS)
The overall global energy scenario is shifting, as the world moves toward the use of renewable energy resources, with the goal of reducing global climate change and carbon footprints. This transition has sped up the growth of inverter-based resources (IBRs), including solar and wind energy generation. With the ramping of demand, many organisations are using the best solar power plant consultants in India to optimise the design and renewables integration of renewable energy projects.
Challenges Posed by IBRs
While IBRs are an important part of the clean energy transition, they challenge grid reliability and stability by:
- Providing committed power.
- Preserving grid stability.
- Lack of or little inertial response.
- Fluctuating power generation due to weather.
Battery Energy Storage Systems (BESS) as a Solution
Battery Energy Storage Systems (BESS) are a promising solution to the issues of higher IBR penetration in the grid. BESS allows for greater renewable sources and increases grid stability with different functions.
Applications of BESS
- Peak Shaving: BESS discharges stored energy to alleviate stress on the grid and help meet peak load demands.
- Renewable Energy Smoothing: The BESS stores excess energy during high production readiness of generation from solar and wind plants and discharges energy when in low production readiness, mitigating variability.
- Ancillary Services: The provision of BESS assists reliability for the overall power system, providing spinning reserves and responding in an instant to fluctuations in frequency.
BESS Configurations
BESS can function as completely standalone systems, or as hybrid systems with a solar PV system and/or wind projects to maximise renewable energy, maximising the potential of the renewable energy and overall power system performance.

Distributed Energy Resource (DER)
The Rise of Renewables and Its Impact on Our Grids
Factors around rapid adoption of renewable energy sources, spurred by a global need to decrease carbon emissions, have started to transformations in the way electricity is both produced and consumed.
In the traditional sense, power generation was done as a centralised, unidirectional activity. In the context of solar rooftops, electric vehicles, and other small-scale source systems, the grid has now become a distributed and interactive system. This growth of Distributed Energy Resources (DERs) presents opportunities for cleaner solutions, but also presents challenges in ensuring grid stability and reliability of the system.
To safely and properly integrate these sources will utilities and industries will need to assess the ramifications at a local and system-wide level. Considerations such as load patterns, the type an electrical grid (on-grid, off-grid or microgrid), and the DER sources diversity (solar, wind, storage, or back-up fuels) are important. This is the reason many companies seek advice from the best solar power plant consultants in India for developing and executing optimised systems.
At QQEC, We Simplify the Complex
At QQEC, we know that integrating renewables into existing energy infrastructure develops technical knowledge as well as determines commercial drivers. In either case, we make things easy by providing systems integrating photovoltaic (PV) systems, Battery Energy Storage System (BESS), and back-up fuel sources into one reliable, optimised system.

Green Hydrogen and Green Ammonia
Green hydrogen and green ammonia are emerging as promising alternatives to fossil fuels in the race for clean energy. Both are produced using renewable sources, making them environmentally friendly options.
- Green Hydrogen: This is hydrogen gas (H₂) produced through electrolysis, where an electric current splits water molecule (H₂O) into hydrogen and oxygen. The key is using renewable electricity sources like solar or wind power to ensure a clean production process with zero carbon emissions. Green hydrogen offers a versatile clean fuel for various applications, including transportation and industrial processes. However, storing and transporting hydrogen can be challenging due to its gaseous nature.
Green Ammonia (NH₃): Made by combining green hydrogen with nitrogen (N₂) from the air through a process called Haber-Bosch synthesis. This results in ammonia, a liquid at room temperature. Green ammonia holds promise for easier storage and transportation compared to hydrogen. Additionally, ammonia is already used in fertilizer production, and it can also be used as a clean fuel for power generation or transportation.
