How do you see the integration of renewable energy sources, particularly wind and solar, impacting the stability and reliability of the electricity grid in the coming years?
SANTIAGO BAÑALES: In Qatar the primary focus is on solar energy rather than wind, as outlined in the Qatar National Renewable Energy Strategy. This initiative aims to achieve 4 GW of centralised solar energy and 200 MW of distributed solar power by 2030. This is significant, especially considering Qatar’s demand peaks at around 9 GW. Maintaining grid stability becomes crucial with such a large share of solar energy.
Grid stability is composed of static and dynamic stability. Static stability balances generation and demand in steady-state conditions, while dynamic stability concerns the small, rapid fluctuations that can disrupt the system. Advanced power simulation technologies are essential to managing both types of instability. These technologies allow us to predict potential issues before they occur, especially with the high penetration capabilities of solar energy.
In addition to simulations, control systems at both the device and system levels are critical. On the device level, inverters and converters must be able to adapt to the changing conditions of the grid in real time. On the system level, operators need control mechanisms to prevent failures and restore balance swiftly when issues arise. Lastly, energy storage will be crucial in balancing the system over different time horizons, ensuring that solar energy is effectively integrated without compromising grid stability.
What role do you foresee for smart grid technologies in enhancing energy efficiency and sustainability in the utilities sector, and how can these technologies be adapted to the region’s specific climatic and operational conditions?
BAÑALES: Smart grid technologies, particularly smart metering, will be vital in driving energy efficiency and meeting Qatar’s ambitious carbon emission reduction target of 25% by 2030. Smart metering allows for real-time energy and water consumption monitoring, providing consumers with the data needed to make more informed decisions. Beyond just monitoring, smart meters can communicate and integrate with broader digital platforms, enabling consumers to adjust their usage based on pricing signals or other incentives.
The three key areas where smart metering can drive efficiency are overall energy consumption reduction, demand flexibility and distributed solar integration. For instance, smart meters can provide real-time data to encourage customers to shift energy use to periods when renewable energy generation is more abundant, such as during midday when solar power peaks.
For distributed solar, smart metering is also critical for understanding energy flows between consumers and the grid, allowing for dynamic pricing and the better integration of rooftop solar systems. In Qatar’s climate, where cooling systems generate significant energy demand, these technologies must be tailored to address the region’s high electricity consumption patterns, especially during peak summer months.
In what ways can the Middle East leverage advancement in energy storage solutions to overcome the intermittency issues associated with large-scale renewable energy deployment?
BAÑALES: Energy storage will be a crucial enabler of renewable energy integration across the Middle East, including Qatar. As solar and wind energy are intermittent, storage systems are necessary to balance supply and demand, especially as renewable capacity grows. For example, Qatar’s target of 4 GW of solar power by 2030 represents a substantial share of its total energy demand, and storage will be critical in managing fluctuations when solar generation is unavailable, such as at night.
The energy storage industry is experiencing rapid advancement, similar to the revolution in solar photovoltaic technologies 20 years ago. Lithium-ion batteries remain the dominant technology due to their decreasing costs and improving performance. That said, other emerging technologies – such as sodium-based batteries – may also play a role in the future. Storage systems help balance the energy supply and provide essential grid services that are crucial for maintaining grid stability as renewable penetration increases.
