Electrical Assets

The following information provides electrical asset definitions and costing elements related to the calculation of operation and maintenance funding and the related activities. Unit cost is one component of the operations and maintenance funding formula. For hydro lines the unit of measure is "kilometres" and for street lights the measure is "each". For mini-hydro and diesel powered electric generators (B3A and B3B asset codes) the costs are derived by using the following annually updated data:

• typical generating plant peak power (where available)
• number, type (make and Model) and generator capacity (kW) for each diesel-generator unit;
• indicate which units are synchronized (i.e. run in parallel on the same bus);
• site fuel costs, fuel consumption, and
• where available, additional calculations and costs (maintenance, consumables, lube oil, etc.) used to derive the estimated O&M cost.

A load factor of 0.5 is to be used where peak power is provided; otherwise, where generator rating in kilowatts (kW) is provided, a capacity factor of 0.35 is to be used.

A sample calculation is as follows:

Peak Power = 50 kW
Energy Potential = 50 kW * 8,760 h/year = 438,000 kWh/year

Load Factor = 50% (on average the peak demand was fully used for 12 hours a day for 365 days)
Therefore estimated energy consumption = 0.5 * 4380,000 kWh/year = 219,000 kWh/year

Cost of fuel delivered = 0.98 $/L
Assume a generator efficiency of 80% and 75%, capacity loading produces 2.86 kWh/L of fuel.
Therefore fuel costs to generate 219,000 kWh = 219,000 kWh/year * 0.98 $/L / 2.86 kWh/L of fuel = 75,042 $/year

40% of cost of fuel is estimated to cover labour, material, travel, lubricating oil, filters, antifreeze, general maintenance and overhaul.

Therefore annual cost of O&M for above example = $75,042 x 1.4 = $105,059

The cost elements for electrical assets (B3C, B3D, B3E) include:

• salaries
• supplies, materials
• equipment and tools

The parameters for Street Lights (B3C) include:

• approximate 60 m pole spacing
• winters do not exceed 6 months
• standard artificial street lighting located south of latitude 57 degrees north

The exclusions for hydro lines (B3D & B3E) are as follows:

• major refurbishing programs where distribution lines have exceeded their expected life
• repairs subject to insurance claims
