Who left the lights on?!
iEN allows corporate clients, through a management platform, to monitor and control energy use in all their sites and fields of activity and moreover implement flexible control. Of course, in order to monitor a client's equipment it is necessary to install related sensors and devices to facilitate transmission of information to, and commands from, the central control platform.
Take schools as an example of how the system could function in practice. The control system can be linked to the digitized schedule of classroom use, so that if a classroom has a class from 10-12 in the morning, the system will turn on the power, lights, and climate control at 9:50, and automatically turn everything off when class is over. If someone wants to use the classroom at non-scheduled times, they have to apply online in advance.
IEN also applies management techniques to "compel" users to change their habits.
For example, if in a certain area of a building people often forget to turn the lights or A/C off when the workday is over, the system will send a text message to the building superintendent, and after the super ensures that no one is in fact working overtime in that area, he can turn off the lights and A/C directly through the system, which makes a record of the action. As a result, there will be "decisive evidence" of which units in the building have the worst habits, and they will not be able to escape being closely watched by central control.
If iEN is applied in a factory, it offers even more amazing possibilities, such as the "optimization" of management of the electrical system. The control system not only provides a statistical overview of the client's actual power use, suggesting a new and more appropriate contract volume, it also provides a detailed analysis of the distribution of power use each month and "dynamic management." For example, it will suggest that the client reschedule certain production-line activity to off-peak hours, when power is cheaper.
In order to ensure that the factory is not fined for power use that exceeds contract volume when it is operating at maximum capacity, the system will precisely calculate the energy use of each piece of equipment or facility, and issue a warning when "critical mass" is reached. At that point, power supply can be temporarily suspended to certain locales in accordance with a priority list drawn up by the client, while those areas that absolutely cannot have any power lapse proceed normally.
Building in incentives
Moreover, because the energy efficiency of a factory's production process is inextricably linked to the energy efficiency of its parts, businesspeople are well aware that they can only increase efficiency by getting new equipment. "But if you only get new machinery but don't maintain it, energy efficiency will get worse year after year."
Wang Gaoxiong, director of the Corporate Services Deparment at CHT, points out that generally speaking, "maintenance" means at most sending someone to inspect and repair equipment at regular intervals. But if there is no long-term data as a standard, engineers often cannot be sure whether energy use has gone beyond normal parameters. With iEN, on the other hand, because there is constant monitoring, whenever any part of any facility experiences a statistical deviation (because, say, parts have come loose), a text message will be sent to the factory to do maintenance. This early warning system, under which gear can be tweaked before enough damage has been done to put it out of order entirely, makes it possible to keep equipment in optimal condition for the long haul, and energy efficiency will not erode over time.
The bill for these advanced services includes (a) system installation and (b) follow-up maintenance and supervision. The former varies depending upon the amounts of monitoring and control equipment required and number of sites, ranging from a few tens of thousands of NT dollars to the tens of millions. (Clients also have the option of renting needed sensors and information systems.) The latter are mostly paid for on a monthly basis.
In the year since iEN has come out, many hospitals, schools, and government agencies have started using it. Regrettably, few private companies have adopted it, largely for lack of government subsidies.
Another reason, one that has been a problem long criticized by environmental activists, is that electricity prices in Taiwan are too low, so there are few incentives for corporations to reduce energy use.
However, CHT estimates that over the next three years there is a potential market of at least NT$2 billion per year. At the same time as they anxiously await changes in government policies, they will take every opportunity to give their troops experience and training, because the planet can't wait, so how can Taiwan?
