Energy Efficiency - Energy Audits

HRL assists clients in identifying, assessing and implementing energy efficiency improvements which are also often greenhouse abatement projects. HRL provides formal energy auditing in accordance with AS 3598. HRL delivers energy audits that are complemented by various State government financial assistance packages including Victoria's Energy Assessment Grants, South Australia's Energy Productivity Program and  NSW's Energy Efficient Business Program.

Challenges

Challenges faced by organisations seeking energy savings start with having the capabilities or finances to:

  • Identify areas where energy can be saved or used more efficiently
  • Investigate the feasibility of any opportunities identified
  • Implement energy savings actions and measuring the impact of those actions  

Solutions

Energy Audits (potentially subsidised, see details for state based schemes below) and Technical Assistance from the experts.

Energy Efficiency Audits

HRL Technology Group is experienced with energy efficiency aspects of many industries. HRL Technology conducts energy audits according to  AS/NZS 3598:2014 and assists to reduce energy consumption and costs on site, including:

  • Detailed analysis of energy consumption and use, relative to industry benchmarks.
  • Detailed analysis of energy costs and the potential benefits of managing energy, with estimated greenhouse gas emissions and any associated costs if required by the organisation.
  • Collection of data for energy review/monitoring purposes.
  • Summary description of audited object and all end uses within this consuming greater than 10% of total energy consumption.
  • Historic energy use including load profiles for at least the last 12 months (recommended 24 months).
  • Sub-meter data, evaluated down to load profile level for significant meters where available.
  • Identification and evaluation of a range of coherent and specific opportunities with specific costs and benefits.
  • Identification of opportunities for which further or more detailed investigation involving measurement is required.
  • Examination of metering systems and recommendations to address data gaps.

Technical Support

HRL Technology Group has a track record in investigating energy issues, providing solutions and implementing those solutions. HRL Technology Group can provide assistance to close the gap between the identification of energy savings opportunities and the actual implementation of the opportunities.

The Technical Assistance services HRL Technology Group offers include:

  • engineering specifications and design provision of drawings and calculations to enable the implementation of energy efficiency projects
  • process modelling and precision measurement capabilities
  • commissioning or tuning of new or existing equipment to ensure maximum energy efficiency outcomes
  • feasibility studies for business case development
  • project management planning of implementation tasks in cost effective and relevant manner
  • product supplier negotiations/tendering assist in tender writing, evaluation and procurement of services/equipment that are energy efficient

Benefits

HRL Technology Group can clients to conduct energy audits and access the subsidised programs, and the benefits to participants that may include:

  1. Access to government funds on a significant scale

  2. Reduced energy consumption and operating costs

  3. Increased efficiency of production

  4. Identification of baseline energy use and projects that may be suitable for other financial assistance (e.g. Emissions Reduction Fund)

  5. Generation of tradeable state based "Energy Savings Certificates"

  6. Increased value and/or use of waste products

  7. Improved business planning

  8. Improved corporate image.


HRL Technology Group comes from a strong engineering and technical background and perspective to assist in evaluating and implementing complex opportunities that have the greater potential to utilise energy more efficiently for the client through energy efficiency improvements.

Sustainability Victoria's Energy and Material Efficiency Grants

Energy Assessment Grants

Boosting Productivity grants are available to help small and medium sized businesses to have an energy audit.

Grants are available to businesses with less than 200 full time employees, spending over $20,000 a year on energy bills.

The grant covers 50% of the cost of an energy assessment at two levels:

  • A basic energy assessment which provides up to $2000 towards the cost of an assessment. This is recommended for businesses spending between $20,000 and $50,000 on energy per annum
  • A detailed energy assessment which provides up to $6000 the assessment.  This is recommended for businesses spending more than $50,000 on energy per annum.

A $3000 implementation bonus is available to both grant types to carry out one or more assessment recommendation, which will result in a reduction in energy (GJ) at the business site.

For more information see http://www.sustainability.vic.gov.au/services-and-advice/business

Energy Efficiency Capability Grants

Grants of up to $150,000 are available for industry associations, business networks and registered training organisations for projects that build the energy efficiency capability of either small and medium sized businesses or service providers.

For more information see http://www.sustainability.vic.gov.au/services-and-advice/business

New South Wales Government's Energy Efficient Business Program

The NSW Energy Efficient Business Program offers subsidies to support projects that businesses undertake to reduce their  electricity and gas consumption.

Options to have 50% of energy audit costs covered or to have a organisation's contribution is capped at $5,000 are available. Further funding for technical assistance are available to organistations who identify viable energy savings projects - and those projects can then go on to generate Energy Savings Certificates (ESCs) to provide further financial value.

HRL, as a member of both the Energy Audit and Technical Assistance panels, can assist businesses participating in the program by undertaking audits and providing technical support.
For further details on the NSW scheme see http://www.environment.nsw.gov.au/business

South Australian Energy Productivity Program

The South Australian Government is providing $31 million to assist large energy using businesses in South Australia to manage their electricity costs and contribute energy supply benefits to the state.

The Energy Productivity Program will be available to businesses that use more than 160MWh of electricity each year to incentivise investment in energy productivity measures.

The program has two components:

  • Energy Productivity Audit Grant Program grants of 75 per cent of the cost of a Level 2 energy audit, up to $15,000, to businesses to engage an external energy auditor to identify energy productivity opportunities.
  • Energy Productivity Implementation Grant Program grants to implement the recommendations of the audits conducted through the Energy Productivity Audit Grant Program or the recommendations of a recently completed energy audit with a preference for projects that provide broader market benefits to South Australia.

For further details on the SA scheme see http://www.statedevelopment.sa.gov.au/resources/energy-efficiency/south-australian-energy-productivity-program

Case Studies

HRL has recently undertaken level 2 energy audits across a range of industries which have all led to identification and investigation of significant energy saving opportunities. In most cases those opportunities have been implemented and the expected savings realised. For example:

Australian brick factories

  • Waste heat recovery to displace natural gas consumption
  • Replacement / improved motors and drives to reduce electricity consumption
  • Power factor correction

Foods, Starches and ethanol plant

  • Boiler combustion efficiency improvement
  • Waste heat recovery
  • Multiple electricity savings measures

Large Australian brewery'

  • Gas savings from boiler and scheduling improvements
  • Steam trap maintenance
  • Improved process insulation
