Some applications to connect a generating unit to TNB network require a technical assessment. This is because we have an obligation to operate, maintain and protect our network to ensure the reliable and secure connection and supply of electricity to our customers.

RE Scheme - Net Energy Metering (NEM)

If an application does not need to be assessed, that does not imply our guarantee of effective operation. It remains the installer's responsibility to do their testing and be confident the proposed generating unit will meet customer performance expectations. Similarly, our assessment are provided at a point in time and are not a guarantee a unit will operate effectively.
For self consumption generating unit of ≥425kW, you need to conduct own PSS to be approved by TNB.

Upon successfully signing the power purchase agreement, you are now ready to connect to TNB network. TNB has released Technical Guidelines for Interconnection of Distributed Generator to Distribution System that focuses on providing recommended practice for utility interconnection of DG systems in a manner that will allow the DG system to perform as expected and be installed at a reasonable cost while not compromising safety or operational issues.
