ABB Energy Appraisal for Lowering Energy Costs and CO2 Emissions
As energy prices continue to fluctuate and industry is
pressured into reducing their carbon foot print, there has never been a better
time to consider the merits of drives and high efficiency motors. An energy
appraisal of your motor driven applications across either a plant or a process
can reveal signification ways to reduce energy costs.
ABB have developed a very simple energy appraisal process
that is carried out by an ABB Engineer with the support of Encompass
Integration your local ABB Authorised Value Partner.
ABB energy appraisalís use a methodical approach that
presents end users with hard, compelling facts about the electricity that they
can save. This is achieved by identifying some key applications that can
benefit immediately from the use of drives and electric motors. This will help
target your investment so that it generates the highest possible savings and
delivers the best return on investment.
ABBís energy appraisal has six steps:
1. Outlining the scope of supply
Encompass Integration and an ABB engineer and will visit your site to get
a clear understanding of your facility including location of applications,
inventory of motors and any health and safety restrictions.
2. Monitoring and data collection
During a walk around the facility we will note typical applications that may be
running inefficiently. The ABB engineer will look at both fixed speed motors
and any drives used to see if the application is running at maximum efficiency.
These selected applications may then be monitored in order to accurately
determine which of your applications are consuming the most energy. It may be
necessary for this to be performed over a seven day period to gain a complete
picture of the plantís typical energy use.
3. Data Analysis
Following the completion of data collection the findings are analysed and
potential saving are identified using dedicated software. The findings are
methodically presented in tables and graphs to help identify where savings are
likely to arise. The data includes an estimation of present energy usage, areas
of potential savings, payback time if an investment is made in drives and
motors, carbon dioxide emission reduction, along with many other key facts and
An action plan, usually comprising an executive summary and a detailed
engineers report, highlighting applications that can save the most is prepared
The figures will normally be translated into monthly savings and there
detailed recommendations for fitting particular drives or motors. Often
the recommendations will show that drives can provide excellent savings
in particular applications. The report shows the expected payback time
fitting new equipment.
Using the recommendations from the energy appraisal, together with ABB we can
identify the correct drive and motor for each application. In many
instances, we can help with the installation and start up or commissioning of
the drive and motor. This includes setting the correct parameters to ensure
that the drive or motor is operating at its optimum energy efficiency.
6. Verification and follow up
Once your new equipment is fitted it is practical to track the actual savings
against the predications shown in the engineers report. This will also help
justify the investment in drives and electric motors. ABB provides life cycle
services to ensure that the drive or motor is looked after throughout its
working life. For example, during the operation and maintenance stage, ABB can
continually monitor the energy consumed by the motor and compare this with the
original specification. It may be that the process is changing or that the
drive or motor is at a specific stage in their maintenance schedules. Whatever
the reason, any deviation can be adjusted to ensure that the drive and the motor
are always performing at their optimum.
During an energy appraisal ABBís engineers can also review
existing business operations and technology to identify the scope for
improvements in energy efficiency and reduced CO2 emissions.
Benefits of an energy appraisal:
- Clearly identified energy savings and CO2 emissions reductions
- Estimated payback times
- Review of current preventative maintenance schemes
- The scope for employing available technology, including drives and electric
motors for applications such as pumps, fans and compressors.
- Low cost or no cost investment opportunities in reducing CO2 emissions
Following an energy appraisal, ABB and Encompass Integration
can offer advice on:
- Replacing drive or motor components as part of a preventive maintenance plan
- Upgrading entire systems to the latest technology or to extend the
functionality of existing drives and motors
- Retrofitting existing drives with modern technology
- Recycling of all removed drives and motors to the latest legislation
