Power Stations In Brunei: Generating Electricity For The Nation

Brunei's power stations primarily produce electricity through natural gas and oil sources, with a small-scale renewable energy project pipeline. The country's electricity sector is overseen by the Department of Electrical Services (DES) and has a total installed capacity of 1,054 MW, serving a small population of approximately 460,000. Natural gas dominates the generation mix, accounting for 95% of the total installed capacity, while the remaining capacity comes from oil-fired power plants. Brunei's power sector has shown reliability, with the government investing in upgrades and modernizations to ensure uninterrupted power delivery.

Natural gas as the dominant energy source

Natural gas is the dominant energy source in Brunei, with the country's electricity sector relying heavily on this resource for power generation. In 2010, natural gas accounted for 99% of Brunei's electricity generation, a significant proportion that highlights its importance in the country's energy mix. This trend has continued, with natural gas supplying 75.6% of the nation's total energy needs in 2005.

The Department of Electrical Services (DES) plays a crucial role in managing the country's electricity sector, operating a diesel power plant (Belingos) and four natural gas power stations: Gadong 1A, Gadong 2, Bukit Panggal, and Lumut. These power stations are responsible for providing electricity to residential areas, meeting approximately 58% of the country's electrical demands.

The remaining 42% of the country's electricity needs are supplied by the Berakas Power Company (BPC), which operates three major natural gas power stations: Berakas, Gadong 3, and Jerudong. These power stations serve strategically important locations, including government buildings, hospitals, and the international airport.

The abundance of natural gas resources in Brunei has contributed to the stability of its electricity supply network. As of 2021, the country's total installed capacity was 1,054 MW, with natural gas accounting for around 95%. This heavy reliance on natural gas for power generation has resulted in a relatively reliable electricity supply, with the government investing in infrastructure upgrades and modernisation to ensure uninterrupted power for its citizens.

While renewable energy sources like solar and wind are not yet widely utilised in Brunei, the country has recognised the need to diversify its energy sources. Brunei has set a strategic plan to include 10% renewable energy sources in its energy mix by 2035, taking steps towards a more sustainable future.

Oil-fired power plants

In Brunei, the electricity sector is regulated by the Department of Electrical Services (DES) under the Ministry of Energy. While natural gas dominates the country's electricity generation, oil-fired power plants play a role in meeting the remaining demand. In 2010, oil-fired power plants contributed to 1% of the country's electricity generation, while natural gas accounted for 99%. The DES operates a diesel power plant (Belingos) and four natural gas power stations (Gadong 1A, Gadong 2, Bukit Panggal, and Lumut).

In recent years, Brunei has recognised the need to diversify its energy sources and has set a goal of including 10% renewable energy sources in its energy mix by 2035. While oil and gas resources remain abundant, the Brunei Vision 2035 Long-Term Development Plan acknowledges the need to support the oil and gas industry while exploring other avenues for economic growth.

Renewable energy sources

Brunei's power stations generate electricity primarily through natural gas and oil sources, with natural gas accounting for around 95-99% of the country's total installed capacity. However, the country has also established goals and initiatives to incorporate more renewable energy sources into its energy mix.

Brunei has abundant oil and gas resources, which means there is no urgent need to develop renewable energy sources. However, the country has recognized the finite nature of these resources and the need to diversify its economy. As a result, Brunei has set ambitious goals for incorporating renewable energy sources into its energy mix.

In 2014, the country adopted a strategic plan, known as Wawasan 2035, with the goal of achieving a 10% share of renewable energy sources in the national energy mix by 2035. This plan outlines the steps to establish renewable energy policies and regulatory frameworks, as well as increase the deployment of solar photovoltaic (PV) technology.

To work towards these goals, Brunei has implemented several initiatives. The country has established a 1.2 MW solar power demonstration facility, with plans to expand it in the future. This facility, known as the Tenaga Suria Brunei photovoltaic power plant, powers approximately 200 homes and helps determine the optimal PV panel for the country's climatic conditions. The Department of Electrical Services assumed control of the facility in 2013 and is responsible for its daily maintenance and operation.

In addition to solar energy, Brunei has also explored other renewable energy sources. The country has set a target of increasing the share of renewable energy in its energy mix to 30% by 2035, focusing primarily on solar energy due to its abundance. The government has also committed to assisting multinational oil and gas companies in meeting their net-zero commitments and developing a carbon pricing or tax mechanism by 2025.

The private sector has also been involved in renewable energy projects in Brunei. The BSP Energy Transition team was established to lead the country's decarbonization process and promote low-carbon solutions. As a result, Brunei's second solar power plant, the 3.3 MW BSP Flagship Solar PV plant, was completed in 2021. This plant has almost 7,000 solar panels and can generate power for approximately 600 homes.

The government has also taken steps to transition its own infrastructure to renewable energy sources. The Temburong District Office became the country's first solar-powered government building in 2021, with 255 solar panels installed on its rooftop. This initiative is expected to reduce annual electricity costs and absorb a significant amount of carbon dioxide.

While Brunei has made strides towards incorporating renewable energy sources, there are still challenges to be addressed. Cost is a significant obstacle, as the country's low electricity prices due to its hydrocarbon resources do not incentivize individuals to adopt renewable energy alternatives. Additionally, a comprehensive regulatory framework for renewable energy development is yet to be implemented.

Power outages and voltage fluctuations

However, power outages can still occur from time to time, particularly during periods of high demand or bad weather. In October 2023, unplanned power outages were reported across the nation, affecting parts of Brunei-Muara, Belait, Tutong, and Temburong districts. This caused disruptions to commercial buildings, offices, and businesses, with individuals stranded in elevators and traffic light malfunctions causing congestion.

The Department of Electrical Services (DES) is responsible for the electricity sector in Brunei, and they actively investigate and address power issues. The government has also implemented measures to mitigate power outages, including regular maintenance and repair of infrastructure, and investment in new power generation capacity.

To strengthen the reliability of power sources, it is important to reduce the country's susceptibility to disturbances, which can lead to power outages and fuel shortages, and the economic hazards that come with them.

Regulatory bodies and their roles

The electricity sector in Brunei is regulated by the Department of Electrical Services (DES) under the Ministry of Energy. The DES is responsible for the generation, transmission, distribution, and sales of electricity in the country. It operates a diesel power plant (Belingos) and four natural gas power stations: Gadong 1A, Gadong 2, Bukit Panggal, and Lumut. These five power plants provide about 58% of the country's electrical needs, mainly serving residential areas.

The Brunei National Energy Company (BNEC) is the state-owned utility company that operates and manages the electricity supply network in the country. Established in 2016, the BNEC is responsible for generating, transmitting, and distributing electricity.

The Oil Conservation Policy, in effect since 1981, is a crucial piece of legislation for the oil sector in Brunei. This policy ensures that the country can meet its commitments to export gas. In addition, the Brunei Natural Gas Policy, created in 2000, supports the gas industry.

In terms of renewable energy, Brunei has a long-term development plan, Brunei Vision 2035, which aims to diversify the economy while supporting the oil and gas industry. The country has set a target of having a 10% share of renewable energy sources in the national energy mix by 2035. While there have been efforts to establish a legal framework for renewable energy development, clear growth plans are still lacking.
