Brand Finance’s inaugural Energy 100 report ranks the most valuable oil & gas as well as utility brands for 2025
KUALA LUMPUR, 5 August 2025 – PETRONAS (brand value down 1% to USD14.4 billion) and Tenaga Nasional (brand value up 35% to USD2.3 billion) have retained their position as ASEAN’s leading brands in the oil & gas and utility sectors respectively, according to the Energy 100 2025 report from Brand Finance, the world's leading brand valuation consultancy.
PETRONAS continues to be perceived as trustworthy and offering good value for money, reinforcing its position as a pillar in the energy sector. In addition, the brand maintains a stronghold in the sector and ranks as the third strongest oil & gas brand globally with a Brand Strength Index (BSI) score of 83.7/100 and an AAA- brand strength rating.
Trailing PETRONAS in the ASEAN region among the most valuable oil & gas brands ranked are Thailand’s PTT (brand value up 11% to USD9.2 billion) and Indonesia’s Pertamina (brand value down 15% to USD3.8 billion).
In the utilities sector, Tenaga Nasional (brand value up 35% to USD2.3 billion) and Indonesia’s PLN (brand value up 30% to USD2.3 billion) are now ranked as the second and third strongest utility brands, respectively.
Tenaga Nasional records a BSI score of 88.9/100 and an AAA brand strength rating, reflecting rising consumer trust and a clear strategic focus on sustainability. Notably, its Green Electricity Tariff (GET) programme has empowered consumers to choose renewable energy at accessible premium rates.
PLN, with a BSI score of 86.2/100 and an AAA brand strength rating, has earned strong stakeholder confidence, particularly through its expanded biomass co-firing initiatives as part of wider decarbonisation efforts. These initiatives also benefit local communities by developing sustainable biomass supply chains.
Alex Haigh, Managing Director Asia Pacific, Brand Finance, commented:
“The strong performance of PETRONAS, Tenaga Nasional, PTT and PLN reflect how ASEAN energy brands are not only competing globally but also leading the way in integrating sustainability into their brand strategies. It’s encouraging to see that investments in green innovation and stakeholder trust are now translating into tangible brand value and strength. These brands are proving that a clear commitment to the energy transition is both a strategic and reputational advantage.”
Meanwhile, Singapore’s SP Group (brand value up 34% to USD1.7 billion) is another ASEAN utility brand entering the rankings this year for the first time, signalling the rising global presence of the region’s utility players.

Brand Finance is the world’s leading brand valuation consultancy. Bridging the gap between marketing and finance, Brand Finance evaluates the strength of brands and quantifies their financial value to help organisations make strategic decisions.
Headquartered in London, Brand Finance operates in over 25 countries. Every year, Brand Finance conducts more than 6,000 brand valuations, supported by original market research, and publishes over 100 reports which rank brands across all sectors and countries.
Brand Finance also operates the Global Brand Equity Monitor, conducting original market research annually on 6,000 brands, surveying more than 175,000 respondents across 41 countries and 31 industry sectors. By combining perceptual data from the Global Brand Equity Monitor with data from its valuation database — the largest brand value database in the world — Brand Finance equips ambitious brand leaders with the data, analytics, and the strategic guidance they need to enhance brand and business value.
In addition to calculating brand value, Brand Finance also determines the relative strength of brands through a balanced scorecard of metrics evaluating marketing investment, stakeholder equity, and business performance, compliant with ISO 20671.
Brand Finance is a regulated accountancy firm and a committed leader in the standardisation of the brand valuation industry. Brand Finance was the first to be certified by independent auditors as compliant with both ISO 10668 and ISO 20671 and has received the official endorsement of the Marketing Accountability Standards Board (MASB) in the United States.
Brand is defined as a marketing-related intangible asset including, but not limited to, names, terms, signs, symbols, logos, and designs, intended to identify goods, services, or entities, creating distinctive images and associations in the minds of stakeholders, thereby generating economic benefits.
Brand strength is the efficacy of a brand’s performance on intangible measures relative to its competitors. Brand Finance evaluates brand strength in a process compliant with ISO 20671, looking at Marketing Investment, Stakeholder Equity, and the impact of those on Business Performance. The data used is derived from Brand Finance’s proprietary market research programme and from publicly available sources.
Each brand is assigned a Brand Strength Index (BSI) score out of 100, which feeds into the brand value calculation. Based on the score, each brand is assigned a corresponding Brand Rating up to AAA+ in a format similar to a credit rating.
Brand Finance calculates the values of brands in its rankings using the Royalty Relief approach – a brand valuation method compliant with the industry standards set in ISO 10668. It involves estimating the likely future revenues that are attributable to a brand by calculating a royalty rate that would be charged for its use, to arrive at a ‘brand value’ understood as a net economic benefit that a brand owner would achieve by licensing the brand in the open market.
The steps in this process are as follows:
1 Calculate brand strength using a balanced scorecard of metrics assessing Marketing Investment, Stakeholder Equity, and Business Performance. Brand strength is expressed as a Brand Strength Index (BSI) score on a scale of 0 to 100.
2 Determine royalty range for each industry, reflecting the importance of brand to purchasing decisions. In luxury, the maximum percentage is high, while in extractive industry, where goods are often commoditised, it is lower. This is done by reviewing comparable licensing agreements sourced from Brand Finance’s extensive database.
3 Calculate royalty rate. The BSI score is applied to the royalty range to arrive at a royalty rate. For example, if the royalty range in a sector is 0-5% and a brand has a BSI score of 80 out of 100, then an appropriate royalty rate for the use of this brand in the given sector will be 4%.
4 Determine brand-specific revenues by estimating a proportion of parent company revenues attributable to a brand.
5 Determine forecast revenues using a function of historic revenues, equity analyst forecasts, and economic growth rates.
6 Apply the royalty rate to the forecast revenues to derive brand revenues.
7 Discount post-tax brand revenues to a net present value which equals the brand value.
