Demand side response (DSR) programs encourage consumers to adjust their electricity use during peak and off-peak times, helping to balance supply and demand on the grid. Participants benefit from financial incentives, reduced energy costs, improved resilience, and support for decarbonisation and emission reduction goals. By shifting, reducing, or storing energy use, companies can play an active role in creating a more proactive and sustainable energy system.
What is Demand Side Response?
Demand side response (DSR) refers to energy flexibility programs offered by utilities that encourage consumers to adjust their electricity use during periods of high or low demand, known as peak and off-peak times, respectively. The main purpose of DSR is to help balance electricity supply and demand, thereby reducing stress on the grid and improving the overall grid stability.
DSR programs typically include financial incentives for participants who alter their consumption in response to grid conditions. The form of these incentives varies by utility provider, but often include reduced electricity prices during off-peak periods, bill credits, or direct payments based on the amount of demand reduced.
What are typical Demand Side Response measures?
To participate in DSR programs, companies need to have visibility of their energy consumption profile and patterns, to have the flexibility to respond to grid signals at high and low electricity demand periods. Typical types of participation include:
- Shifting energy-intensive operations or processes to off-peak periods when electricity demand and prices are lower.
- Reducing electricity demand at peak times by shutting off non-essential processes or equipment through simple energy efficiency measures.
- Utilising battery storage systems to store electricity at off-peak times to then utilise or sell back to the grid at times of high electricity demand.
- Implementation of on-site generation, such as solar PV, reduces reliance on the electricity grid. Any surplus of electricity generation can also be exported and sold back to the grid.
What are the benefits of Demand Side Response?
Beyond helping to stabilise and balance the electricity grid, DSR programs can provide a range of direct and indirect benefits to the companies.
- Companies having to monitor and understand their energy patterns gives them insight into areas of operations with energy โhot spotsโ. Having this knowledge enables them to invest in methods to optimise these processes to increase their energy efficiency.
- Utilising energy storage such as batteries and on-site generation reduces the companyโs reliance on the grid and are therefore able to withstand any grid outages or disruptions.
- Having the flexibility to shift consumption to off-peak periods, allows companies to avoid high electricity charges resulting in financial savings.
- Companies implementing on-site renewable energy generation, such as solar PV, directly supports in the companyโs decarbonisation journey by reducing their carbon emissions.
