Heat metering brief

The Concept of Smart Metering Heat Energy

Presentation at NEMEX 2011

The Concept of Smart Metering Heat Energy - A lot more than heat metering.

How do you measure energy consumption, when water is the media carrying the energy?

The smart heat meter is a multifunctional meter that provides an abundance of useful information. It provides knowledge about the use of energy: how much, where, and when it was consumed; and it facilitates effective energy saving, in an area little addressed until now.

How do they work? Since the 1990's the use of micro processing technology has opened up new possibilities in addition to the core function of measuring energy.

The smart heat meter supports systems that provide cooling in summer and heating in winter, enabling differential billing. Due to a variety of interfaces for temperature and flow sensors, the smart heat meter can provide an exact picture of energy consumption including system temperature monitoring.

The heat meter is also capable of controlling a motor valve that controls delivery of energy to the consumer.

The smart heat meter contains its own logger storing all relevant information at predetermined intervals. Consumer issues can be detected precisely, and the diagnosis made within minutes.

The smart heat meter has communication technologies such as, GSM, M-Bus, LONWorks or ZigBee , which provide a flexible interface for integration into BMS and AMR. Remote reading provides the information needed for more efficient administration.

Heat metering completes the triangle of energy measurement, where gas and electricity have formed the other two sides of the picture to date

80% of consumers should have smart meters by 2020

As you know these are exciting times for our industry. With the European Commission estimating that the EU is on course to achieve only half of the 20% primary energy consumption savings objective, the next 2 years will be key to define your roll-out strategy to ensure that 80% of the customers will have a smart meter by 2020.

To achieve this massive target, the industry is facing the difficult task in defining the requirements for EU standards, security guidelines, data privacy legislation, meeting future customer demands and technologies needed to achieve a global smart architecture.

Dubai ,DEWA CEO Al Tayer is keen to raise awareness of conservation amongst Dubai's residents.

Dubai Water and Electricity Authority (DEWA) CEO and managing director Saeed Mohammed Al Tayer has said that smart metering will be rolled out in Dubai within six months.

“We have already started to look into smart metering. The commissioning will be within six months,” confirmed Al Tayer at the signing of a Memorandum of Understanding (MoU) with the Dubai Courts, designed to promote energy and water conservation amongst the department’s workers.

Smart metering devices give utilities and end users more information about consumption, and help utilities to bill consumers according to their use of power and water. Conversely, they help end users to keep track of and reduce their consumption.

As in other GCC countries, per captia consumption in Dubai far exceeds the world average. With both water and electricity is subsidised, DEWA is looking to contain growing demand with a host of measures to raise environmental awareness and reduce power and water use, according to the CEO.

Al Tayer mentioned district cooling as one of the areas where DEWA is looking for efficiency gains. “We are now waiting for district cooling providers to modify their plants with thermal storage, because with their current plants are not sufficient for energy reduction,” said Al Tayer.

New district cooling plants are required to be fitted with thermal energy storage, which reduced energy consumption during peak loads. DEWA is also encouraging the use of treated wastewater to reduce the amount of desalinated water, Al Tayer said.
