What are grid technologies?
Traditional grid technologies connect businesses to a one-way electricity network. Energy flows in a controlled way, and is provided by large, semi-centralised utility companies.
Smart grid technologies, on the other hand, enable bi-directional communication between businesses and electricity networks. They facilitate a more advanced level of monitoring and automation, and enable dynamic adjustments to energy flow.
Unlike traditional grids, smart grids can reliably accommodate the integration of renewable technologies. This means they can balance the supply and demand of energy more effectively.
Another common term used in relation to grid technology is micro grid. These are small, localised energy systems that usually operate independently, or in connection with larger traditional grids. They typically serve a specific area, like a neighbourhood, campus, or a single building.
How do grid technologies work?
Grid technologies improve communication between the various components of a power network. They do this by relaying information from consumers to generation plants. A key factor in transmitting consumer data is the installation of smart meters in business spaces. These digital devices enable two-way communication about both supply and demand between producers and consumers.
With data analysis technologies and Internet of Things (IoT), generation plants can analyse consumer data and predict periods of high usage. This enables energy companies to adopt demand response programmes that empower businesses to move their consumption to off-peak hours.
As such, smart grids improve the efficiency of traditional grids. They create opportunities to integrate cleaner renewable technologies like solar and wind into the network. Energy storage technologies like batteries can also be integrated into smart grids to store excess energy.
How are smart grid technologies used?
When combined with IoT technology, smart grids can improve the security of electricity supplies. They mitigate the chance of outages, and reduce greenhouse gas emissions.
For example, smart grids are often used alongside renewable technology, distributed generation, and electric vehicle charging infrastructure. They’re often used in the development of smart buildings, substation automation, and feeder automation.
Smart grid technologies can also be used to detect faults in electrical devices and equipment, resolving issues quickly and safely.
The benefits of smart grid technologies
Here are some of the main benefits of smart grid technologies:
Enhancing energy efficiency
By monitoring electricity distribution more effectively, smart grids allow utility companies to detect and respond to changes in energy demand quickly.
In turn, this reduces energy waste by balancing supply with demand. It also minimises transmission losses.
Smart grids also support intermittent renewable energy sources and enable businesses to make informed energy choices through smart meters.
Reducing costs for businesses and utility companies
Smart grids offer businesses more predictable pricing. By moderating spikes in energy usage, smart grids help prevent sudden increases in energy costs. This allows businesses to anticipate their energy expenses more accurately.
Likewise, automated responses to grid issues allow utility companies to identify, diagnose, and resolve faults without human intervention.
This proactive approach reduces the time and manual labour required for manual inspections and repairs, thus lowering maintenance costs.
Enabling electric vehicle integration
Smart grids support the integration of electric vehicles (EVs) by managing the additional demand they place on the power grid.
Through real-time data, and intelligent demand response, smart grids allow EVs to charge during off-peak hours. This prevents grid overload and lowers energy costs for EV fleet owners.
Smart grids also enable two-way charging, where EVs can return stored energy to the grid during high-demand periods.
Improving energy market flexibility
With advanced metering and communication technologies, smart grids allow for dynamic pricing. This is where energy costs reflect demand, enabling businesses to adjust their usage as they need.
Smart grids also enable decentralised energy generation, which means small-scale producers can sell excess power back to the grid.
These capabilities make the energy market more responsive, efficient, and resilient.
The role of grid technologies in decarbonisation
According to a 2023 report published by the International Energy Agency (IEA), digitalisation in grids could reduce the curtailment of renewable energy systems by more than 25% by 2030. Indeed, smart grids enable producers (and consequently businesses) to diversify their energy sources, strengthening our energy systems.
As previously mentioned, smart grids help network operators manage the balance between supply and demand. With adaptive control capabilities, smart grids optimise energy distribution. This improves stability and reliability across industrial energy demand.
Likewise, integrating smart grids with battery storage can improve the value of stored energy. By deploying stored energy during peak demand times, businesses become less reliant on expensive, high-demand power sources.
Similarly, optimising the timings when stored energy is released, smart grids can help prevent waste. They can maximise battery lifespan, and create revenue opportunities for businesses to sell energy back to the grid.
