Sarawak Energy Design Challenge

Design Challenge 1: Power Outage Prediction Model

Sarawak Energy is committed to deliver reliable power supply to more than six hundred thousand customers throughout the state of Sarawak. Over the years, Sarawak Energy is continuously improving the power supply reliability through various initiatives such as mobile field force, smart grid, remote monitoring system, etc.

There are various causes of power outage, some are predictable and while some others are unpredictable. For transmission line, the cause of power outage is mainly contributed by lightning, others can be animals likes snake, squirrel, etc. For distribution line, normally strong wind is the main cause contributing to the power outage. In order to further improve the electricity grid reliability, correlating weather data and power outage occurence may help to predict potential of power outage. 

The design challenge is to develop a power outage prediction model based on weather dataset provided to predict which transmission line could be tripped due to lightning few days in advance.

Teams will be provided the following key dataset:

  1. Lightning (2 years) – Lightning type (intra Cloud (IC), Cloud to Ground (CG)), polarity (positive or negative discharge), amplitude and coordinate of lightning strike.
  2. Travel Wave System (2 years) – Fault location information, time and waveform. The waveform can be used to determine the cause of tripping either lightning or animal.
  3. Tripping report (7 years) – Summary of tripping location, time and cause of tripping.
  4. Weather data (4 years) – Rainfall, wind speed, wind direction, humidity and temperature

Design Challenge 2: Street Lighting Remote Monitoring System

The street lighting has been deployed in large number across the state of Sarawak. Currently, there is no remote monitoring system deployed to monitor the condition of the street lighting. Therefore, the condition of street lighting is always unknown until the public lodge the complaints on faulty street light.

The design challenge is to design a low-cost and low-power remote monitoring devices/sensor nodes that are able to work perfectly with low-power wide area network, such as LoRa, NB-IoT, or RF mesh. The remote monitoring devices/sensor nodes need to be able to detect the working condition of the street lights. The collected information need to be sent to central monitoring system and alert users when there is any faulty street light.

Sarawak Energy Berhad is an energy development company and a vertically integrated power utility with a vision to achieve sustainable growth and prosperity for Sarawak by meeting the region's need for reliable and renewable energy—providing electricity to 2.8 million Sarawakians in urban and rural areas.

Built on a foundation of almost 100 years of experience, our role is to provide reliable, safe, and competitively-priced power. Our energy predominantly comes from Sarawak’s rich hydropower resources, making our energy supply environmentally friendly and sustainable. We are the primary electricity provider in Sarawak, with an expanding consumer base of more than 680,000 account holders throughout Sarawak and a growing multidisciplinary workforce of 5,000. Sarawak Energy is the largest employer of professional Sarawak talent.

We are now taking bold steps to support Sarawak’s goal of achieving developed status by 2030. In advancing the agenda of sustainable and continuous growth, a strategy roadmap is designed to consolidate, protect and optimise the value created from the transformation of a traditional utility into a corporate power house and digital utility of the future by focusing on excellence in operation and Health Safety and Environment (HSE), project delivery and talent management enabled by a high performance organisational culture.
