How do I get my system connected to the grid?
You will need to apply to interconnect your BIPV system with the utility’s grid system. This can be done by calling up your PV Service Provider (PVSP) and informing him/her of your interest.
The PVSP will obtain the PV Generator Interconnection Application Form through one of these channels:
- by downloading it from the website - PTM PV Form
- obtaining it from the PTM office; or
- obtaining it from the TNB District offices
After successfully filling up the forms, the PVSP will submit the forms to PTM (MBIPV) for processing. PTM (MBIPV) will verify the interconnection details and approve the application for grid connection. The approved application will then be processed by the utility (TNB for installations in Peninsular Malaysia). Please refer to Flowchart 1-Interconnection with TNB for more information on the process flow for interconnection
Net-Metering
What is Net Metering and how does it work?
TNB Distribution has agreed for BIPV generating systems to be connected to its network on a Net-Metering concept for recording the electricity generated by the BIPV system. The BIPV generated electricity is fed back into the grid at the point of supply if it is not needed at the site at the time.
Net metering is a scheme to generate revenue for the electricity generated by the BIPV systems to be sold to the utility. It operates by deducting the electricity generated by the BIPV system (recorded by the PV meter) from the electricity used as purchased from the utility (recorded by the utility meter) to determine the “net” electricity the consumer uses and is required to pay for. The two meters will be placed side-by-side at the point of the utility’s electricity supply in the case of residential premises as shown below.
Net Metering agreement will enable residential customers to ‘store’ the electricity on the TNB grid if they are not at home during the day (when PV is generating electricity) thus reducing or offsetting part of the electricity that would have been purchased from the utility for the day. This will reduce their electricity bill!
Will I be eligible for it?
Yes, if you are a residential or commercial electricity customer in Malaysia with a BIPV installation whose capacity in kWp is less than the maximum demand of the consumer load.
What is the buy-back rate like under Net Metering?
It is the same as the prevailing supply tariff. For residential consumers, the buy-back rate shall be the highest rate of the block tariff that they pay (RM 0.46per kWh in Peninsular Malaysia as of 1st July 2008 if the consumption is over 900 kWh per month, or lower according to the tariff block under the TNB’s tariff now in effect (from 1 July 2008).
What is the billing mechanism like under Net Metering?
The electricity bill will record the total electricity generated from the BIPV system and the total electricity supplied by the utility, TNB. The TNB bill will then be for the net electricity supplied by TNB to the user. If the electricity generated from BIPV exceeds the total supplied by TNB for any period, the balance (surplus BIPV generated electricity, if any) shall be brought forward to the following month. TNB does not commit to pay for the surplus electricity from the BIPV installation. However, for residential consumers, the BIPV electricity generation is not expected to be more than their normal use over a yearly period
How can I get my BIPV system connected up for Net-Metering?
Just call up your preferred approved service provider and inform them of your interest and they will carry out the necessary steps.
*The approved service providers will fill up the PV Generator Interconnection Application Form and submit it to PTM (MBIPV) for processing.
