Key Changes in the SELCO Guidelines
The SELCO Guidelines are not applicable to installations which construction commenced before 1 January 2025.
The key changes introduced in the SELCO Guidelines are as follows:
- Removal of Capacity Limit: Previously, there was a capacity limit of 85% of the consumer's maximum demand. Under the new SELCO Guidelines, there is no capacity limit for Non-Standalone / Grid-Connected systems for non-domestic consumers. This change is expected to better support corporations and industries in reducing their carbon footprint while fulfilling Environmental, Social, and Governance (ESG) commitments.
- Expanded Coverage: The SELCO Guidelines now allow solar system installations for electricity users in the agriculture category, broadening access to green electricity as well as configurations beyond building rooftops, including ground-mounted solar systems and floating solar systems on water bodies within the consumer's premises. This expansion is in response to demands for solar installations on land and water bodies.
- Standby Charge: The new SELCO Guidelines imposes a RM14/kWp standby charge on all installations constructed after 1 January 2025. This charge is intended to cover the costs associated with maintaining the stability and reliability of the grid. Following the Minister's Announcement, the standby charge will be reduced to RM12/kWp for installation capacities over 1 MWp and installations with a capacity below 1 MWp are exempted from the standby charge.
- Battery Energy Storage System (BESS) Requirement: Non-Standalone / Grid-Connected systems with a capacity of over 72kWp will be required to install a BESS with the same or greater capacity. This requirement aims to ensure the overall stability of the electricity supply system. All categories are now exempted from the BESS requirement until 31 December 2025 as a result of the Minister's Announcement.
- Connection Assessment Study: The Power System Study has been replaced with a connection assessment study for any solar PV installation exceeding 72kW. This new assessment process will be conducted by the consultant who prepared the design of the solar PV installation.
Remark
The new SELCO Guidelines represent a significant step forward in Malaysia's energy transition efforts, offering greater flexibility and expanded opportunities for solar PV installations. By removing the previous capacity limit and allowing installations beyond rooftops, the SELCO Guidelines aim to support corporate and industrial (C&I) sectors in meeting their ESG commitments and reducing their carbon footprint. However, while private companies can now obtain their entire electricity demand from solar PV installations, the new requirements introduce additional costs despite the improvements from the Minister's Announcement. The mandatory installation of BESS for larger systems post 2025 and the imposition of standby charges will increase the overall expense of solar PV projects. These financial burdens may potentially hamper the private development of solar generation in the C&I sector. That said, given the impending electricity tariff increase in July 2025 and potentially significant tariffs increases in the future due to the removal of subsidy and cost of conventional fuel, the C&I customers may want to consider purchasing renewable energy from solar PV installations albeit at a slightly higher rate but with the rate being locked in for 15-20 years.
