Documents Required
Kafalat Energy applications should enclose all the documents requested for Kafalat files.
In addition, the Client should provide one additional document pertaining to the energy project: a Technico-Financial Study. This study combines a detailed system design, which should follow sound engineering practice, and a financial analysis which should highlight the costs and revenues of the project. It must be prepared by a mechanical, electrical or energy engineer contracted by the Client.
Below are some guidelines on the content of this Technico-Financial Study which is different for Programme A and Programmes B & C. Applications taking into consideration all of the design paramters mentioned below will be processed faster.
Programme A - Energy Efficiency
- Current Situation Energy Audit: An energy audit is required with each file. It should present the base case (current) energy consumption calculations, and indicate all constraints to potential energy efficiency recommendations. Supportive documents such as EDL bills and generator/diesel bills must be provided.
- System Design Considerations: The technical solutions selected must be optimized for technical feasibility, energy benefits and costs. In addition, the engineering design of the systems must meet engineering standards and best practice. This is to ensure a fault free operation, and reduce operation costs.
- Energy Savings Calculation: The energy calculation of the current situation and of the new improved scenario could be either performed by hand, or using a simulation software. If done by hand, the calculation must be explained reasonably and accurately. If a computer simulation is used (which could be performed on a range of tools, from the complicated TRNSYS, to a basic Excel spreadsheet, according to the complexity of the project), the simulation input variables and design parameters must be correctly set in the software, and presented in detail.
- Key Energy Indicators: The results should emphasize the energy benefits of the project. They could be presented as follows:
- Total energy Saved in kWh/year
- Overall decrease in energy consumption in % of the “Current Situation”
- Energy Saved in kWh/year for each sub-system installed
- % decrease in energy consumption for each sub-system
- Total Reduction in CO2 emissions in tons of CO2. This information is mandatory.
- Key Financial Indicators: They should be justified by pro-forma invoices, previous energy bills of the facility, and take into account the time value of money.
- Capital cost of all components
- Engineering and Installation costs
- Operation and Maintenance costs
- Savings-to-Investment ratio (SIR)
- Levelised Cost of Energy
- Net Present Value of project
Programmes B & C - Renewable Energy
- Current Energy Situation: The report should detail the current sources of energy generation, costs and problems. Supportive documents such as EDL bills and generator/diesel bills must be provided. In addition, the resources of the proposed renewable energy solution must be presented along with all the site constraints.
- System Design Considerations: The design must be coherent such that equipment sizing, selection and specifications are optimal. All losses must be accounted for, and all electrical connections compliant to applicable standards. This is to ensure a fault free operation, and reduce operation costs.
- Energy Yield Calculation: The energy yield calculations must be accurately performed with a computer-based calculation tool, and take into consideration all the previously mentioned parameters. If available, commercial or proprietary software should be used. If not available, the calculation steps will be explained and justified in detail. In any case the calculation must include a comparison to a business as usual scenario.
- Key Energy Indicators: The results should emphasize the energy benefits of the project. They could be presented as follows:
- Total energy yield in kWh/year
- Specific energy yield in kWh/kWinstalled
- Performance Ratio (PR) in %
- Overall System Conversion Efficiency in %
- Nominal output current in A
- Nominal output power in kW
- Avoided CO2 emissions in tons of CO2. This information is mandatory.
- Key Financial Indicators: They should be justified by pro-forma invoices, previous energy bills of the facility, and take into account the time value of money.
- Capital cost of all components
- Engineering and Installation costs
- Operation and Maintenance costs
- Savings-to-Investment ratio (SIR)
- Levelised Cost of Energy
- Net Present Value of project
