Demand Side Response (DSR) is an advanced form of energy management that balances the demand on the national grid, through on-site energy reduction at times of ‘peak power’. With the right type of electricity contract and intelligent application of your Building Management System (BMS), it is possible to re-engineer the demand of a commercial building to reduce costs.
Although still in its infancy in the UK, DSR is due to become more popular as distribution and transmission costs become ever more expensive. Electricity suppliers are therefore rewarding customers that are able to use less energy during the peak demand periods on the grid, through reduced costs.
‘Peak power’ is when the electricity supply grid is at its most stretched. It is also the most expensive time of the day to generate electricity. Recently, this has become ever more prevalent , due to the decommissioning of the UK’s aged nuclear power stations, the lack of uncertainty around their replacement, plus the unreliability of wind and solar generation on the power network.
In order to secure additional value for our customers, E2 focuses on 3 key areas within our DSR programmes:
Energy demand in most organisations peaks at around the same time of day, putting undue pressure on an already fragile generation & distribution network.
By re-engineering the electricity usage within the ‘peak power’ period, it is possible to make your organisation’s energy profile much more attractive to the electricity market, which will result in cheaper contract prices.
E2’s engineers identify areas where load can be reduced and put in place revised control strategies to automate the process, whilst ensuring there is no detrimental effect to the building or its occupants. This technique can reduce a typical site’s electricity bill by up to 5.0% for no capital investment.
As an additional £100 billion is invested into the national grid, distribution charges are on the increase. These are now grouped into ‘Red, Amber & Green’ periods and charged directly on to customers.
Most businesses are heavy users in the late afternoon when the ‘Red’ period hits. E2’s engineers assess your building services and control strategies and identify key areas where load can be shifted for short periods.
Once the measures are shortlisted, these are discussed & agreed with the client. E2’s engineers then implement the improved control strategy and undertake a series of tests, to ensure there are no adverse effects on the occupiers of the buildings.
The changes are then fully automated & ongoing monitoring is provided by E2’s Energy Bureau.
Customers are charged for the amount of energy consumed during the 3 peaks on the national grid each year. These are known as ‘Triad’ charges.
It is possible to reduce your Triad charges by taking ownership of your organisation’s energy demand during these peak periods.
The majority of consumers pay a ‘bundled price’ for their Triad usage, based on estimates by the suppliers. By taking ownership of your Triad periods, significant savings can be achieved.
E2’s engineers work with you to develop a Triad strategy, utilising a variety of load reduction techniques. The Triad strategy is then written into your BMS system, so that it can be initiated either by E2’s energy bureau or via your on-site staff.
