Maximizing Solar Energy at Ansasol's Photovoltaic Plant

The challenge

One of the main challenges of photovoltaic plants is the sale of the energy produced to the electricity grid in the most efficient and cost-effective way possible. Since the price of electricity varies throughout the day, plants without a storage system must discharge their production in real time, which often means selling at low prices. In addition, at times of high renewable generation, the system operator can apply “curtailment” (mandatory reduction in production) to avoid overloads on the grid, further limiting economic use.

The main problems that Ansasol asked us to solve were:

• Intermittency of renewable energy: The variable nature of solar production hinders grid stability, increasing uncertainty in the electricity supply. ‍
• Energy price variability: Without a storage system, the plant was forced to sell its production at the time of generation, without the possibility of choosing the most profitable periods.‍
• Economic maximization: At times of high renewable generation and low demand, the forced reduction in production prevented maximizing revenues.

The solution

Integration of a 20'' BESS - BCube® system

To meet Ansasol's specific needs, at BeePlanet Factory we designed and manufactured a fully customized storage system. A 20-foot BCube® with 1,190 kWh of capacity. A modular and scalable system that not only allows for more efficient and flexible solar energy management but can also adapt to future expansions.  

The system enables:

• ‍Energy arbitrage: The BCube® facilitates buying and selling electricity at the most cost-effective times, maximizing the value of the electricity produced and optimizing plant revenue. ‍
• Real-time regulation: Adjusting energy injection into the grid based on market conditions, improving grid stability and benefiting from specific energy markets that reward these capabilities.

‍

Beyond these economic and operational benefits, energy storage contributes to cleaner and more efficient energy:

• Lower CO₂ emissions: By storing renewable energy, the use of fossil fuels is reduced, contributing to the decarbonization of the power grid. ‍
• Power grid stabilization: It helps stabilize the grid and prevents blackouts or interruptions, especially in less robust electrical systems. This translates into a secure and flexible energy supply. ‍
• Greater energy efficiency: natural resource utilization is maximized, preventing waste.
