The key business segments of the company are power generation, merchant multi-utilities, water and sewerage, telecommunications, data centers, digital banking, and investment holding activities.

The development of the combined cycle power plant was financed through a ringgit denominated currency, facilitated by the first 15-year long term bond issued by the Employees Provident Fund (EPF).

[6] Subsequently in September 2017, the Paka power plant was awarded a supplementary PPA for a further period of 3 years and 10 months.

Wessex Water is a regional water and sewerage service company that serves 2.9 million customers across a geographic area of approximately 10,000 square kilometres in the southwest of England, including Dorset, Somerset, Bristol, most of Wiltshire and parts of Gloucestershire and Hampshire.

In 2018, YTL PowerSeraya re-established its retail brand in Singapore as Geneco (previously known as Seraya Eneegy).

[13] In 2022, YTL PowerSeraya acquired Tuaspring Pte Ltd, a 396 MW combined cycle gas turbine power plant in Singapore.

[15] In 2023, YTL PowerSeraya collaborated with TNB Power Generation Sdn Bhd for the export and import of 100MW of electricity to Singapore via a newly upgraded interconnector.

[16] In January 2024, YTL PowerSeraya won the first request for proposal (RFP) for the development of a 600MW hydrogen-ready CCGT under Singapore’s Energy Market Authority’s new centralised process and it is expected to be completed by 31 December 2027.

[2] Under the 1BestariNet programme, Yes worked with the Malaysian Ministry of Education to provide 10,000 primary and secondary national schools across the country with high-speed 4G internet connection and to use the cloud-based Frog VLE (Virtual Learning Environment) platform.

Sundar Pichai noted that the “pace at which 4G connectivity is being rolled out throughout the country and what’s happening in Malaysia can be a role model for many other countries around the world.”[19] In 2016, the 4G brand under YTL Comms was the first mobile operator in Malaysia to introduce Voice-over-LTE (VoLTE) capability for high-definition and crystal-clear calls.

Despite using basic hardware configurations, users can now enjoy playing games on high display settings, up to RTX On in 1080p at 60FPS.

Additionally, YTL Power will utilise NVIDIA’s AI cloud computing platform to build a large language model in Malay.

NVIDIA’s CEO Jensen Huang mentioned that Malaysia is an important hub for Southeast Asia's computing infrastructure, which requires access to land, facilities and power, and YTL could play a significant role in that.

The platform acts as a single GPU with 1.4 exaflops of AI performance and 30TB of fast memory and is designed for the most compute-intensive workloads.

The current project under development is Brabazon – a new "urban community" that will comprise new homes, employment space, new schools and a town-center.
