Client Overview.

Ecovantage was engaged by a biogas consultant who designs and builds biogas plants, to conduct a feasibility study for the creation of energy certificates on behalf of their client. Located in Victoria, the client operates a food manufacturing facility and is implementing an anaerobic digestion system to generate energy and reduce waste from food scraps going to landfill.

This case study is part of a combined project with ACCU Generation through Biowaste featured project.

Project Summary.

Ecovantage will measure the reduction of natural gas consumption through onsite biogas production, conversion to biomethane and use within industrial boilers onsite. This activity is incentivised to promote self-generation of energy from waste that would otherwise go to landfill, and reduce the reliance on natural gas as a fuel source.

Working with the biogas consultant, Ecovantage measured historic waste levels and the volume of natural gas used at the facility. This would then be directly compared to the actual biogas and natural gas consumption post-upgrade. This data is used to forecast the site’s net carbon reduction and the corresponding number of VEECs eligible to be created over the life of the project.

Ecovantage will manage the measurement and verification of the system and manage the creation and monetisation of the VEECs over a 12-18 month period once implemented.

Savings Summary.

	Estimated annual biogas production: 41,470 GJ		Estimated annual electricity reduction 2,922 MWh
	Estimated annual biogas consumption: 26,500 GJ		Estimated total VEECs created: 8,834
	Estimated client ROI: $684,710

Measurement & Verification Process.

1. Develop a Baseline Energy Model

Through analysis of provided energy data from previous years, a baseline energy consumption model is developed.

2. Develop an Operating Savings Model

Once the site has been operating for a 12 month period, a final operating model is completed. Frequent mid-way models are completed over this period to ensure that the site is on track to achieve the targeted savings.

3. Measure the Savings & Generate Certificates

The Avoided Energy (measured savings) are quantified by comparing the site’s energy consumption prior-to and post-project implementation. Based on the energy, and therefore nominal carbon savings resulting from the project, the total number of VEECs are able to be calculated and created. This is forecast to total almost 9,000 VEECs, generating almost $700,000 for the client.

Project Takeaways.

Working with an experienced Accredited Certificate Provider (ACP) and M&V specialist is essential to ensuring your project is not only accurately measured and monetised, but to provide confidence that all creation options have been assessed and you get the highest return for your project.

This case study combined with ACCU Generation through Biowaste featured project demonstrates how one project can attract multiple savings incentives, delivering a substantial impact to the project’s ROI.

By using two certificate creation methods for the overarching project, the project is forecast ot generate $3,200,000 in white certificates and carbon credits over its lifetime.
