Connecting Electrons: Introduction to electricity grid infrastructure, equipment, and technologies
The first session of Connecting Energies 2024 focused on the fundamental components of the electricity grid and their functions, including substations, transformers, overhead lines, and underground cables that grid operators used to transport electricity efficiently across regions.
Introduction
We also covered the technologies used to integrate renewable energy into existing grid infrastructure, such as smart grids, digitalisation, and advanced monitoring systems, which were essential for decarbonising and modernising the grid.
As these technologies evolved, participants gained insights into the current challenges and future trends in grid infrastructure and supply chains, including the need for grid flexibility, real-time data processing, and upgrades to handle variable renewable energy sources. A keen understanding of these aspects was essential for anyone advocating faster integration of renewables.

Connecting Energies 2024
The Renewables Grid Initiative invited participants to Connecting Energies 2024, an expert-led training series designed to equip civil society with the knowledge needed to advocate for a decarbonised, renewables-based, and affordable energy system. This three-part webinar series covered fundamental aspects of the electricity system, including grid technologies, load balancing, flexibility, and electricity metering and pricing. Participants gained key insights into how grid infrastructure, technologies, and market mechanisms evolved to support the energy transition.
The sessions provided a deep dive into the physical components of the grid; key technologies and approaches that enabled the integration of renewable energy and ensured that green electricity was delivered at every hour, every day of the week (24/7); and the challenges and opportunities related to metering and pricing. Each session focused on practical concepts that NGOs could leverage in their advocacy efforts to drive faster renewable energy adoption and to support grid development and expansion. Whether participants were new to energy systems or looking to deepen their understanding, this training provided essential knowledge to support the shift to a net-zero future.
