Instructions The case study submission can only be made from a provisionally accredited person or fully accredited person seeking points as part of the CPD program.

If you are applying for micro hydro accreditation you must be the person who undertook the installation (you cannot sub-contract to others). Therefore your name shall be the one appearing on all relevant documentation including testing and commissioning Sheets.

The installation must have taken place during your period of accreditation. Work that was carried out prior to accreditation being granted will not be accepted.

Important:

Any electrical work involving components of up to 48VAC and 120VDC must be carried out by a competent practitioner.

All other electrical work must be carried out by a licensed electrician.

The applicant must be the commissioning installer for all MHT related components and all ELV- related components and aspects of the system.

All photographs, design information, testing and commissioning sheets and any other evidence must be from the same installation. Multiple installation pictures will render the case study void and a new case study will be required.

Please note: The Clean Energy Council has a 5 MB limit on incoming emails. You may need to resize your images if you are submitting them via email.

Case study assessment ratings

Competent: An applicant will be deemed competent when the assessor is satisfied that there is sufficient evidence that the installation has been conducted to all current and relevant standards and guidelines and that supporting evidence has been sighted as evidence of this compliance.

Not yet Competent: An applicant will be deemed not yet competent when the assessor is not satisfied that there is sufficient evidence that the installation has been conducted to all current and relevant standards and guidelines and that insufficient supporting evidence has been sighted as evidence of this compliance.

Failed: An applicant will be deemed failed/rejected in the following circumstances:

The applicant has repeatedly failed to submit the required information to the Clean


Energy Council’s accreditation administration department.

The applicant has not submitted the correct information to the technical assessor within the allocated time. The assessor will only request this information once, and failure to provide the correct technical information will result in the application being rejected. A fail result will require the applicant to make a new submission and additional charges will apply.

The Assessor deems that the evidence provided shows an MHT installation that may be mechanically or electrically unsafe and may cause physical harm to people or property.

The applicant has submitted a false electrical license or is not licensed to carry out the work.

The applicant has not met the minimal training standard / completed the necessary training units as required to make the application.

The assessor deems that the MHT installation is in clear breach of AS/NZS 3000 wiring rules.

A fail result will require the applicant to make a new submission and additional charges will apply.

D-03 System Performance Estimate and Energy Resource Assessment

Under CEC design guidelines, the designer must be able to:

Estimate the gross energy available to the standalone MHT system

Estimate the net energy yield provided by the system (after any system, battery or other losses)

Estimate any seasonal variation in energy resource

Identify what portion of local energy demand will be met by the MHT system

Identify the most suitable source(s) for local energy demand not met by the MHT system These calculations should be made using methods consistent with best practice and relevant standards. There may be commercial tools available to assist in calculating energy yield. At a minimum, you must provide:

1. Evidence that the MHT voltage, current and other specifications are matched to the battery, charger and inverter specifications, and other components where relevant

2. Expected net annual energy yield (in kWh) for this system, with workings

3. Average daily performance estimate (in kWh) for the best month of MH generation, noting possible annual variance.

4. Average daily performance estimate (in kWh) for the worst month of MH generation, noting possible annual variance.

5. Estimated number of months per year at or near full capacity of MH generation, noting possible annual variance.

6. Estimated number of months per year at or near zero MH generation, noting possible annual variance.

7. Estimated number of months per year at partial MH generation, noting possible annual variance.

8. The source of estimated flow data, and/or appropriate workings.

9. Description of other energy sources where the MH is not expected to provide all local energy needs.

The number of days of redundancy built into the battery system

Manufacturer’s graphs or tables indicating rated output under different levels of head and flow.
