For renewable energy stakeholders, the "Energy Reset" pillar is particularly significant, as it outlines how Singapore aims to transform its energy landscape.

Key Energy Reset Targets:

• Quadruple solar energy deployment to 2 gigawatt-peak (GWp) by 2030
• Reduce energy consumption in HDB towns by 15% by 2030
• Green 80% of buildings by 2030
• Make all new car registrations clean energy vehicles from 2030
• Increase EV charging points from 28,000 to 60,000 by 2030

Solar Energy Initiatives

Given Singapore's equatorial location and high solar irradiance, solar energy has been identified as the most promising renewable energy source for the nation. The government has implemented several key initiatives to accelerate solar adoption:

SolarNova Program

The SolarNova program, led by the Economic Development Board (EDB) and Housing & Development Board (HDB), aggregates solar demand across government agencies to achieve economies of scale. Through this program:

• Solar panels are installed on the rooftops of HDB buildings and other government sites
• The program operates on a solar leasing model, with private companies financing, building, and operating the solar photovoltaic systems
• Government agencies then purchase the solar energy generated at a competitive rate

By 2030, the SolarNova program aims to deploy 1.5 GWp of solar capacity across 70% of HDB rooftops.

SolarPV Marketplace and Solar Generation Map

The Energy Market Authority (EMA) has developed digital platforms to facilitate solar adoption:

• The SolarPV Marketplace connects consumers with solar installers, simplifying the process of sourcing for solar services
• The Singapore Solar Map provides a visual representation of where solar panels have been installed across the island, along with real-time data on solar generation

Floating Solar Farms

To overcome land constraints, Singapore has pioneered the development of floating solar photovoltaic (PV) systems:

• The Tengeh Reservoir floating solar farm, completed in 2021, spans 45 hectares and can generate enough electricity to power about 16,000 four-room HDB flats
• Additional floating solar systems have been deployed at Bedok and Lower Seletar reservoirs
• PUB, Singapore's National Water Agency, aims to deploy at least 100 MWp of floating solar PV on reservoirs by 2030

Enhanced Central Intermediary Scheme

The Enhanced Central Intermediary Scheme (ECIS) simplifies the process for consumers with small-scale solar installations to sell excess solar energy back to the grid:

• SP Group acts as a central intermediary, purchasing excess solar energy at prevailing market rates
• This eliminates the need for small solar generators to register directly with the wholesale electricity market
• The scheme applies to residential and commercial installations with a capacity of less than 10 MWp

Wind Energy Support
