As the world moves to reduce CO₂ emissions, the electricity sector – which still relies heavily on fossil fuels – presents both challenges and opportunities for decarbonization. Real-time data that enables accurate monitoring of emissions is emerging as a crucial tool. This type of tracking, developed and implemented by the International Energy Agency (IEA), provides a granular and near-immediate view of the climate impact of electricity grids. With this data, it is possible to manage electricity demand at times when renewables are available, reducing the sector’s carbon footprint.
Benefits of Real-Time Data Integration in Emissions Management
Electric grids are sensitive to a range of variables, from supply and demand shocks caused by external events to seasonal patterns and daily weather variations. Collecting emissions data in real time allows policymakers and grid operators to dynamically monitor climate impacts, adjusting strategies accordingly as energy generation and consumption changes. This monitoring also makes it easier to create pricing policies and incentives for lower carbon intensity times, encouraging demand to shift to times when clean energy generation is abundant.
Cases such as Colombia, where falling hydroelectric reservoir levels have led to increased emissions, demonstrate the value of this data. By monitoring hourly, monthly and seasonal variations in CO₂ intensity, it is possible to respond quickly to extreme variations, whether due to weather events or fluctuations in the use of renewable energy. This type of monitoring not only promotes the resilience of the electricity system, but also optimizes the use of clean energy, reducing the environmental and financial costs of the grid.
Transparency and Accuracy in Corporate Emissions Reporting
Real-time emissions tracking also addresses a growing demand for transparency in private sector emissions reporting. In recent years, companies across a range of sectors have adopted ambitious emissions reduction targets, but traditional calculation methods based on annual intensity factors do not capture the true variability of emissions from electricity consumed. Access to real-time data, on the other hand, allows for more accurate reporting, directly correlated with the time of physical delivery of electricity.
The IEA’s proposed real-time monitoring methodology addresses discrepancies in previous calculation methods, particularly location-based and market-based approaches that often underestimate the true emissions associated with consumption. While the monitoring system does not yet cover all distributed generation or small facilities, its progress points to a faster decarbonization of electricity grids, aligning consumption with the supply of clean electricity. This granularity of data can encourage new electricity procurement and load management strategies by companies, driving decarbonization and commitment to global climate goals.
With the development and continuous improvement of these monitoring technologies, the electricity sector can become one of the greatest allies in the fight against climate change, leading a smart and efficient energy transition.
