Singapore’s solar energy landscape: innovations and policies driving the green transition

Singapore is rapidly transforming its energy landscape with a strong focus on solar power. The Energy Market Authority (EMA) has set an ambitious target of achieving at least 2 gigawatt-peak (GWp) of installed solar capacity by 2030. This would be sufficient to power approximately 350,000 households. Let's delve into the innovative strategies and policies driving Singapore's solar energy revolution.

Maximizing Solar Potential: Innovative Deployment Strategies

Singapore is exploring diverse avenues to harness solar energy effectively.

Rooftop Solar Power: The SolarNova Program

• The SolarNova program is a government initiative to encourage rooftop solar installations on HDB flats and public buildings.
• By aggregating demand, this program aims to accelerate solar adoption and reduce costs.
• Rooftop solar panels convert underutilized space into clean energy generators.

Floating Solar Farms: Harnessing Water Bodies

• Singapore is leveraging its water bodies for solar power generation through floating solar farms.
• The Sembcorp Tengeh Floating Solar Farm is a prime example, showcasing the potential of this innovative approach.
• Floating solar farms help optimize land use and contribute to Singapore's green energy goals.

SolarLand Program: Utilizing Vacant Land

• JTC's SolarLand program transforms temporary vacant land into solar power plants.
• Modular solar systems are deployed in locations like Jurong Island and Changi Business Park.
• This strategy efficiently utilizes available space for clean energy production.

Building Integrated Photovoltaics (BIPV)

• BIPV systems integrate solar panels into building facades and roofs, enhancing aesthetics and energy generation.
• This approach promotes sustainable urban development and reduces reliance on traditional power sources.

Policy Framework: Driving Solar Energy Adoption

The EMA has implemented several policies to foster solar energy growth:

• Intermittency Pricing Mechanism (IPM): Adjusts electricity prices based on solar power availability, ensuring fair cost allocation.
• Solar Aggregator Model: Streamlines processes for solar aggregators, facilitating solar energy trading.
• Master-Sub Setup: Explores options for buildings under master-sub schemes to benefit from solar power.

Overcoming Challenges: Ensuring Solar Reliability

Solar power's intermittent nature requires careful management:

• Solar Forecasting Model: Developed in collaboration with the National University of Singapore, this model predicts solar power output.
• Energy Storage Systems (ESS): ESS technologies help balance solar power fluctuations and ensure grid stability.

Key Solar Initiatives in Singapore

Conclusion

Singapore's commitment to solar energy is evident in its ambitious targets and innovative approaches. By maximizing rooftop potential, harnessing water bodies, utilizing vacant land, and integrating solar into buildings, the country is leading the way in sustainable energy solutions. The EMA's supportive policies and efforts to address solar intermittency further strengthen Singapore's position as a global leader in clean energy.
