Installation of Solar Photovoltaic Rooftop and Energy Auditing Programme in Temburong District

18 April 2020

The Ministry of Energy have recently introduced two sustainable energy related-projects – 8KW solar photovoltaic rooftop installation project and energy auditing programme in Temburong District. The projects aim to encourage the deployment of the renewable energy technologies as well as to ensure that the energy saving opportunities are prudently optimized in Temburong District. These projects will support the Temburong Development Authority (AKDT) initiatives and project masterplan.

The Ministry through the Department of Electrical Services (DES) and Sustainable Energy Division led an installation of 8kW solar rooftop on a three-floor shop houses at Bumiputra Commercial Building in Temburong. Once completed, this initiative will be the first government-led solar project in Temburong, advocating the district's "green concept". This is part of the Ministry's ongoing effort to integrate Renewable Energy into the national power generation mix in realizing Brunei's vision 2035.  

Led by the Ministry's Sustainable Energy Division with the support of Department of Electrical Services (DES), the construction of began in early April 2020 by a local contractor and is expected to be completed by late April 2020. It is estimated that this solar PV system will produce approximately 10,500 kWh per year. This is equivalent to a reduction of carbon emission of about 2,838 kg of CO2 per year and the reduction of diesel consumption of 4,200 litres per year.

It is a pilot project to test the solar photovoltaic set-up for the anticipated Net-Metering Scheme, a mechanism that allows excess energy from the solar photovoltaic rooftop system to be exported into the grid. In this regard, the Ministry welcomes involvement of higher educational institutions in the country, as well as other Non-Government Organizations (NGOs), to partake in the analysis during the pilot project period.  

The Ministry has launched an energy auditing programme on government buildings in Temburong District in February 2020. The energy audits are conducted by the Ministry's certified Energy Manager and Energy Auditor from the ASEAN Energy Manager Training and Certification Programme under ASEAN-Japan Energy Efficiency Partnership (AJEEP) scheme. All government office buildings in Temburong District are expected to meet the mandated Energy Efficiency Index (EEI) of 175 kilowatt hours per square meter per year as part of the requirement under Brunei Accredited Green Unified Seal (BAGUS) produced by the Ministry of Development (MOD) in order to be awarded with the Building Energy Label (BEL) Recognition Certificate. The BEL is designed using star rating criteria; 1 star represents less efficient and 5 stars as the most efficient office building. The Energy Auditor will also provide some recommendations on office buildings that are rated below 5 stars to further improve their energy performance and be audited annually. It is also plan to extend the energy auditing programme to Commercial Buildings in Temburong District in collaboration with the Ministry of Development.

The Ministry also plans to develop a user friendly Application Software which serves to make energy auditing be self-implemented in all sectors. Information on the Apps will soon be available online via the Ministry website.

Temburong is a special District in Brunei Darussalam, known for its pristine forests and greeneries. Both sustainable energy related projects which are currently undertaken by the Ministry in Temburong District are only the first initial step.  More green projects are slated to be undertaken by the Ministry in the short to medium term.
