Reducing electrical demand during peak hours: smart solutions for Irish businesses

Reducing electrical demand

In an era where sustainability and cost-efficiency are paramount, Irish business owners are increasingly focusing on reducing their electrical demand, especially during peak hours. This not only lowers operational costs but also contributes to the stability of the national grid. Leveraging smart and low carbon technologies and shifting behaviours and loads can provide significant benefits.

Peak hours, typically occurring during early morning and late afternoon (5pm – 7PM) and are when electricity demand is at its highest. This increased demand strains the grid, leading to higher electricity costs, higher carbon emissions, increased carbon intensity of the grid and increases disruptions. By reducing consumption during these times, businesses can take advantage of lower tariffs and contribute to a more balanced and reliable energy supply for everyone.

1. Smart Meters and Real-Time Monitoring

Smart meters are essential for understanding and managing energy use. They monitor real-time data on consumption patterns and provide 36 hours of previous energy data. This allows businesses to identify when and where energy is being used the most. ESB Networks has been rolling out smart meters across Ireland, making it easier for businesses to access detailed energy data. By analysing this data, businesses can pinpoint peak usage times and take steps to shift non-essential activities to off-peak hours.

2. Demand Response

Participating in demand response projects and investing in demand response technology can be highly beneficial. These projects incentivise businesses to reduce their electricity use during peak times in exchange for financial rewards. By integrating automated systems that can temporarily lower lighting, HVAC, and other non-critical loads, businesses can participate in these programs with minimal disruption to their operations

3. Energy Management Systems (EMS)

Advanced Energy Management Systems (EMS) integrate data from smart meters and other sensors to provide a comprehensive view of a business’s energy consumption. These systems can automatically adjust energy use based on real-time data, optimising consumption patterns to avoid peak hours. EMS can be tailored to specific business needs, ensuring that critical operations remain unaffected while reducing overall energy costs.

4. Upgrading to Energy-Efficient Equipment

Investing in energy-efficient equipment can significantly reduce demand. High-efficiency HVAC systems, LED lighting, upgrades to building fabric and modern machinery consume less power and are often more reliable. Although the initial investment may be higher, the long-term savings and potential grants from SEAI can offset these costs.

5. Renewable Energy Integration: Solar Panels and Wind Turbines

Integrating renewable energy sources like solar panels and wind turbines can help businesses generate their own electricity, reducing dependence on the grid during peak hours. Ireland’s climate is suitable for both solar and wind energy, and ESB Networks supports the integration of these technologies. By generating renewable energy, businesses can not only lower their electricity bills but also contribute to a greener environment.

6. Renewable Energy Integration: Heat Pumps and Battery Storage Systems

Heat pumps are an eco-friendly and cost-effective means of heating and cooling businesses by transferring heat between indoor and outdoor environments. They use electricity to run the pump. Battery storage systems allow businesses to store excess energy generated during off-peak times or from renewable sources. This upgrade in heating system and stored energy can then be used in combination during peak hours, reducing the need to draw from the grid. Advanced renewable systems can also be integrated with EMS for seamless energy management.

7. Behavioural and Operational Changes: Shifting Non-Essential Activities

One of the simplest ways to reduce peak demand is by shifting non-essential activities to off-peak hours. For example, scheduling heavy machinery operations, non-critical manufacturing processes, or intensive computing tasks during times when electricity demand is lower can lead to significant savings. Promoting an energy-conscious culture within the workplace can lead to substantial reductions in energy use. Encouraging employees to turn off lights, equipment, and machines when not in use, and to be mindful of peak hours, can collectively contribute to lower demand.

Embracing smart tech

By embracing smart network and energy technologies, Irish business owners can effectively manage their electrical demand during peak hours. By taking these steps, businesses can play a crucial role in building a sustainable and resilient energy future for Ireland.
