Net Energy Metering
- NEM is a Self-Consumption Model.
- Excess energy is fed into the Grid in the Day
- Energy injected to the Grid is used to contra the Electricity used at night.
- Applicable to both Residential and Commercial.
- Capex for NEM is less than for Large Scale Solar, due to grid connection an earthwork consideration.
- Solar Panels shade your roof, creating a cooler working environment.
- NEM does not need to cut down trees.
- NEM makes use of space you do not consciously use.
- Because of government incentives till 2020, your payback from NEM is half that of Large Scale Solar projects.
Installation Types and Capacity Limits
• On the rooftop of building; and
• On the garage, car park, and similar buildings
• For domestic or residential consumers, the maximum capacity of the PV system installed shall be 75% of maximum demand. New Suruhanjaya Tenaga guidelines has release the cap of 1MWp system.
• For commercial and industrial consumers, the maximum capacity of the PV system installed shall be:
a) 75% of maximum demand of the consumer’s current installation (for current transformer metering), whichever is lower;
i. based on the past 1 year average of the recorded maximum demand of the consumer’s installation;
ii. the declared maximum demand for consumers with less than 1 year;
b) 60% of fuse rating (for direct meter) or 60% of current transformer (CT) rating for low voltage consumers.
The credit (excess energy) to NEM consumer will be based on prevailing Displaced Cost for the relevant supply voltage level at the Point of Common Coupling. The calculation for the net billing of electricity will be based on the following calculation:
Net billing = [Energy Consume from DL (kWh) x Gazetted Tariff] – [Energy Exported to DL (kWh) x Displaced Cost]
The net billing or credit shall be allowed to roll over for a maximum of 24 months. Any available credits after 24 months will be forfeite.
