A Green Energy Hub for a Sustainable Tomorrow

CLP Power is focused on decarbonising its power business, and its Ho To West Substation project won at the Asian Power Awards for its environmentally-friendly design.

Solar panels will be installed on the roof to capture sunlight and convert it into power to run the substation. A rainwater harvest system will reduce freshwater consumption by 80% while water-efficient fixtures will reduce sewage by more than 50%.

Energy-saving LED lighting and other energyefficient installations will meanwhile reduce carbon emissions by 10%, and electric vehicle chargers will be fitted in the substation to encourage green motoring and further reduce emissions.

As well as its green features, the design symbolises the close partnership between Hong Kong and the Mainland with twisting architectural fins on the exterior walls representing the coming together of the two Greater Bay Area cities of Shenzhen and Hong Kong.

A Model Development

Creating a sustainable energy future is more than an abstract concept: it is an objective that can sometimes be seen, felt, and experienced in the very fabric of the facilities and buildings needed to make it a reality.

CLP Power’s Ho To West 132kV Substation project in Hong Kong is an outstanding example—an inspired development that mirrors its purpose as an energy hub of the future and is as different from a traditional functional electricity substation as you could imagine.

With solar panels and vegetation covering its rooftop and vertical walls, a rainwater harvest system, and a host of other energy-saving features, it is a substation meticulously designed to help Hong Kong towards a sustainable tomorrow.

CLP Power won the gold award for Transmission & Distribution Project of the Year at the Asian Power Awards for the substation’s design, reflecting the company’s commitment to innovate and decarbonise and to be an influential agent in the fight against climate change.

An Engine

for Sustainable Growth

Ho To West Substation will provide a world-class power supply to the Lok Ma Chau Loop area serving the Hong Kong-Shenzhen Innovation and Technology Park, an exciting new hub for hi-tech research and development and creative industries.

Fringed by the meandering Shenzhen River, the park is designed to strengthen the strategic role of Hong Kong and Shenzhen in the Pan-Pearl River Delta regional cooperation framework.

CLP Power adopted an innovative, green design for the substation to optimise its environmental performance and to echo the theme of sustainable development that permeates the Lok Ma Chau Loop area.

An Intelligent Green Design

The substation will be built on a compact site and has been designed to minimise its visual impact on the neighbourhood. It will be only two storeys high and will have vegetation on its rooftop and vertical walls to make it blend into the surrounding green environment.

The vegetation will not only make the substation a more attractive and comfortable workplace but will also play a role in supporting the surrounding microclimate.

Cutting-edge technologies have been deployed in the creation of the new substation, including Building Information Modelling, Virtual Reality, and Computational Fluid Dynamics modelling.

The use of these technologies has allowed CLP Power to create a 3D model of the substation in the early design stages to show all project stakeholders and demonstrate how it can be built and operated with a vastly reduced carbon footprint. During the construction stage, green practices will be implemented to reduce building waste by 70%.

Environmental considerations have been put at the forefront of CLP Power’s thinking throughout the project planning process, from material selection to energy efficiency and water conservation.

CLP Power Senior Director of Power Systems Mr Eric Cheung said CLP Power was honoured to receive the award for the substation as it recognised the efforts of the project team. “CLP Power is committed to decarbonise our business and provide reliable and greener energy to our customers,” he said. “We will continue to adopt sustainable features and innovative technology as we design our future substations.”

The Ho To West Substation reflects CLP Power’s commitment to sustainability and will be a milestone on Hong Kong’s journey to achieve carbon neutrality before 2050.

It is a project that bridges the gap between what is possible and what is achievable, drawing on technology and dedication to environmental targets to create a green energy hub and a substation for a sustainable future.
