Optimizing industrial self-consumption with Bright Sunday

Discover the new use case about autoconsumption

The main challenge for Bright Sunday in its projects in Spain is to optimize industrial self-consumption while strictly complying with Royal Decree 244/2019, which requires precise energy management under the zero-injection mode.

This involves ensuring that no energy is exported to the electrical grid, coordinating photovoltaic production with consumption in real time through advanced control systems, guaranteeing a certified technical solution that avoids regulatory risks, and at the same time maximizing profitability by optimally adjusting generation to the customer’s demand.

Efficient solar self-consumption solution:
Bright Sunday requires a solution that enables efficient solar self-consumption while ensuring full regulatory compliance and stable system operation.

A key requirement is real-time control of surplus energy to prevent any export to the grid.
In Spain, Royal Decree 244/2019 regulates self-consumption systems. Under certain grid constraints or connection conditions, installations must operate in zero-injection mode, meaning that no energy is allowed to be exported to the public grid.

To comply with this requirement, a certified anti-export control system is mandatory. This system must guarantee zero injection at all times using a fast closed-loop control architecture, typically with a response time of less than 2 ms, enabling immediate adjustment of inverter output based on production and consumption variations.

WebdynSunPM provides a certified and scalable control solution designed for these requirements, ensuring real-time export limitation (≤ 2 ms response time) while optimizing the performance and operation of photovoltaic installations.

This approach ensures full compliance with RD 244/2019 and grid operator requirements, while maintaining high system efficiency and operational stability.
