"Supply companies will need to learn about DR possibilities and efficiencies"

Interview with Alastair Manson, senior consultant, Engage Consulting Limited

The decision to go for a demand response programme in case of businesses depends upon a number of factors. For such initiatives, organisations have to diligently plan, implement, and monitor activities, which best fits in with the kind of business they are in, scale of their operations and other factors.

While for smaller retailers there might be not be a lot of electric load they can shift to off peak times, for relatively larger businesses the issues tend to be much more complex considering decisions related to production schedules, selection of equipment and much more.

Still, the general consensus seems to be that the understanding of such process, which is all about reducing load when contingencies occur that threaten supply-demand balance or market conditions occur that raise supply costs, is only gradually picking up.

"You would have to say that there is a lot to be learnt. There is much that is understood about demand response but more that is not known. Similarly, the generation profile will change in ways that are unknown," says Alastair Manson, senior consultant, Engage Consulting Limited.

Manson, who is scheduled to speak during Intelligent Demand Response for Electricity Summit 2009, to be held in Amsterdam on 28-29 January 2009, says smart meters do not in themselves deliver demand response but can offer a number of ways that can provide or facilitate various levels of demand response: They can be linked to displays (giving consumption and pricing information including potentially CPP); They can have load limiting capability – in line or auxiliary switches that could control all or part of supply; They can be linked to other devices in the home directly or via an energy control device to allow automated management of devices usage and so on.

"It is probably fair to say that suppliers are investigating various levels of load control and with various levels of sophistication but that our initial challenge in Great Britain is to get the implementation of smart metering underway with the right functionality to allow for options to be decided into the future," Manson told smartelectricnews.com.

DR programmes are like other programmes but there is a particular need to learn along they way and to take in innovation, says Manson.

According to Manson, supply companies will need to learn about DR possibilities and efficiencies.

"There is a constant learning process and they need to keep learning what is effective with customers and what customer's abilities to change usage are. They need to understand what the rules are and have an understanding of what the rules will be and keep learning what technologies can provide," he added.

Automated DR systems have been deployed for critical peak pricing and demand bidding and are being designed for real time pricing.

On how does automating DR allows greater levels of participation and improved reliability and repeatability of the demand response and customer facilities, Manson said automation will suit many customers who will not want to manually micro-manage their consumption.

"It is a service that has to be seen as acceptable to customers rather than being inflicted on them. There needs to be an education process from suppliers and beyond including government. There needs to be an energy service to customers not just an energy supply service. Customers need to appreciate benefits of DR -this will take learning and time and they will need alternatives that make DR acceptable and a benefit rather than just reducing their demand," said Manson.

While the lack of knowledge about how to develop and implement DR control strategies is a barrier to participation in DR programs like CPP, another barrier is the lack of automation of DR systems.

At least one way that DR can be facilitated is via smart metering with sufficient abilities.

"But DR cannot be implemented by stealth," said Manson.


In terms of opting between Manual DR programme, and Semi-Automated DR, which involves a pre-programmed demand response strategy initiated by a person via centralised control system, and Fully-Automated Demand Response, which does not involve human intervention, but is initiated at a home, building, or facility through receipt of an external communications signal, Manson said this has to be done by study of what works and what is acceptable to and desired by customers, bearing in mind that conditions may well be very different not so far in the future.

Recently, it was indicated that less than one percent of all commercial and industrial companies use advanced technology to measure and manage energy spend, whereas nearly 100 percent use advanced technology to measure and manage telecommunications spend in the US.

Assessing the situation as far as the maturity level of Advanced Metering in Total Energy Management in the UK is concerned, Manson said, "I would be surprised if it is really one percent. I would have to say that UK is in its infancy but will grow quickly."
