Cities will become less energy-consuming and eventually energy-positive. We facilitate this energy transition in two ways: first by producing renewable energy adapted to the territory, such as solar energy in Singapore and in the Asian tropical sunbelt; second by adding an intelligence layer to existing power grids, in order to integrate intermittent and dispersed renewable energy and new uses such as electric vehicles. The French expertise covers the whole energy chain, from production to distribution.
While Singapore currently generates 95% of its power from natural gas, the city plans to reach 350 MWp (megawatt-peak) of photovoltaic capacity installed by 2020, up from 25-30 MWp in 2015. This target will be mostly met by photovoltaic panels installed through innovative business models on HDB rooftops, also contributing to reduce the heat island effect locally.
Solar Plants and Connection to the Grid
Offer ranging from complete turnkey solar power plants to individual components. The technology can be adapted to work for all project types and sizes, including both hybrid power generation and all-solar power plants.
Complete solution for photovoltaic integration and connection including power conversion, electrical distribution and supervision (inverters, transformers, and switchgear).
Portfolio of photovoltaic ICs: cool bypass switches designed to improve the reliability of panel electronics, and DC-DC converters to maximise power conversion of solar panels independently of temperature and the amount of solar irradiation.
ST is also developing new technologies like Silicon Carbide to create power solutions with excellent switching performance, translating into more efficient and compact systems.
Financing and Leasing of Rooftop Solar Plants
Solar financing solutions replicate the economic model of conventional electricity: the consumer produces the green electrons and pays for the green energy consumed, but not for the solar modules. The energy not consumed locally can be exported to the grid.
Solar PV systems built, owned and operated by a Solar Independent Power Producer for commercial, industrial and public sites in the Asia Pacific region. Full range of solar services to install solar photovoltaic systems on the unused rooft ops and sites spaces of customers, through a Power Purchase Agreement. Without spending any resources, customers benefit from lower and more predictable utility costs, and enjoy stronger sustainability branding.
Other Renewable Energies
Other renewable energies may be experimented in Singapore on a small-scale with the intent of exporting the technology to Asian countries (cf. example of Semakau Landfi ll infra): onshore and off shore wind, hydro, geothermal, biomass, biogas, wave and tidal power. Together we offer solutions at all stages of the development process: project management, financing, design, building, operation, and maintenance.
SAMPLE OF OUR KNOW-HOW
- Rooftop solar plants in Singapore
LYS Energy is deploying roughly 4 MW of solar photovoltaic projects in Singapore, producing green electrons that are mainly consumed locally by the clients: 81 kWp in Woodlands, 226 kWp in Buena Vista, and a 3.1 MWp solar photovoltaic system comprising a rooftop installation and a solar carport under construction in Seletar. Solar photovoltaic installations reduce the temperature below the roof by 15°C in average.
Integrating renewable energy into the grid implies to manage intermittent and decentralised power. A smart grid aims to ensure a stable and consistent power supply through energy management and storage systems. It consists of an electricity network equipped with digital automated controls and bidirectional communication technologies, ideally in all areas (generation, transmission, distribution, customer level).
Smart Energy Metering
Smart meters are the first brick of a smart grid, collecting data in real-time along the value chain. They enable energy providers to reduce manual meter reading cost, consumers to better understand and manage their energy consumption at the electrical device level, and grid operators to optimise power distribution and outage management.
Titanium Smart Metering Platform: vendor agnostic robust, flexible platform to support smart metering rollout and operation services. Full data collection, supervision, and remote management of meters.
Complete set of semiconductor products to implement energy, water, heat and gas meters, as well as concentrators or multi utility-controllers.
Remote metering based on long range technology. The solution’s fixed network architecture allows consistent remote metering, ensuring the reliability of collected data and the billing of actual consumption.
Cloudboard®: a video camera solution that monitors and supplies information on a region’s current cloud cover in order to optimise renewable energy production. It provides a short term forecast of how the cloud cover will evolve using an estimate of how fast the cloud is moving: this helps grid operators to anticipate a decrease in the solar energy production.
Energy Management Systems
An energy management system optimises production and consumption, and automates operations at different levels. Grid maintenance is based on preventive measures and automatic response to system incidents, ensuring self-healing network.
Community Energy Management System: a software that monitors, analyses and optimises energy usage within territories; it integrates a soft ware simulation engine combining big data, complex systems and predictive analytics, developed by CoSMo, a French and Silicon Valley based software editor.
e-terraODM platform and SystemX (R&D): real-time and cloud-based big data analytics platform to support decision-making by handling connected objects in energy and transportation, including smart meters, distributed photovoltaic systems, electric vehicles, distributed storage, and new distributed generation.

Energy Automation for Substations that Distribute Electricity
DS Agile Smart Digital Substation: it transforms traditional power substations by installing optical sensors and Intelligent Electronic Devices (IEDs) to enhance the electricity analysis and automatically respond to current faults and risks detected; it provides network reliability, reduction in carbon footprint and better safety. DS Agile Digital Substation Solutions are highly scalable in terms of equipment, functions, architectures and services.
PACiS (Digital Control System for Substation Automation): a scalable and customisable solution dedicated to energy automation that includes protection devices, measurement centres, bay controllers, communication devices, analysis tools such as a disturbance analysis viewer, IED setting and engineering tools.
Demand Response Management to Control Peak Electricity Demand
DRBizNet platform: it enables intentional modifi cations to consumption patterns, by shift ing or mitigating peak demand, in order to reduce electricity use at times of high wholesale market prices or when system reliability is jeopardised.
Energy Storage Systems
Energy storage solutions can be installed at all levels of the power grid to better control and integrate the energy from intermittent renewable sources. Batteries make the grid more predictive by scaling up or down to absorb short-term (e.g. cloudy weather), daily (e.g. evening) or seasonal fluctuations.
Alstom’s MaxSineTM eStorage solution, connected to Saft ’s Intensium® Max 20M storage system: a complete energy storage and conversion system that optimises energy efficiency, enables more flexible grid management and controls energy balance across the energy supply chain. It uses battery storage through conventional and renewable power for functions that include demand response for industries, peak shaving, generator hybridisation, regulating frequency and load levelling to reduce the required capacity for power generation. It is the only solution able to handle megawatt-scale storage.
Blue Zone: batteries of 180 kWh to 1 MWh that store renewable energy and provide continuous and sustainable power in areas where electricity is diffi cult and expensive to bring through a cable. Blue Zone allows the production of drinkable water as well as education, sport, and healthcare infrastructure.
EXAMPLE OF SUCCESSFUL COLLABORATION
- A test-bed to develop a hybrid micro-grid
Nanyang Technological University (NTU) is implementing a hybrid micro-grid called Renewable Energy Integration Demonstrator Singapore (REIDS), with the support of the Economic Development Board (EDB) and the National Environment Agency (NEA). The hybrid micro-grid will be located at NTU’s EcoCampus and subsequently off shore at Semakau Landfi ll. Its main goal is to test the integration of solar, wind, tidal-current, diesel, energy storage, and power-to-gas Technologies. Th e micro-grid solution can also be used to power small islands and rural communities off the national grid or may function as a back-up solution during emergencies within urban areas.
Overall the test-bed provides a unique platform to develop and commercialise energy technologies suited for the tropical climate, positioning Singapore to meet the growing demand in Asia.
10 top industry partners participate in the REIDS initiative, including:
- ENGIE develops the SPORE project (Sustainable Powering of Off -grid REgions) to enable the management of multifluid systems (electricity, hydrogen, biogas, and cooling) and different storage capacities on islands. The project also includes the demand side management of semi-industrial building bricks (desalination, cold storage, electric vehicles). In 3 years the project will result in a showcase solution for Southeast Asia.
- Alstom develops a unique MicroGrid Power Mix Management solution based on its Digital Automation Platform, to manage power exchanges within the microgrid both when it is connected to or separated from the main grid.
- Schneider Electric provides its Advanced Distribution Management System to integrate different decentralised energy sources and also supports solar solutions (bidirectional inverter) and smart grid solutions.
- IssyGridR, France’s first operational district smart grid
France is actively looking for energy innovative solutions. In 2014 a call has been issued for new smart grid demonstrators including one at the regional scale.
Located in the south-west of Paris, Issy-les-Moulineaux is the first city in France with a smart grid network in operation. Development started in 2011 and extends over 5 years. Starting with a business district of 160,000 m2, it will be extended to the whole city. IssyGrid® is developed by a consortium of 10 companies led by the French group Bouygues (Dragages).
So far, the IssyGrid platform manages in real-time generation of renewable energies (target of more than 1,000 m2 of photovoltaic installations), consumption (housing, office buildings, shops, street lighting), and storage (batteries, electric vehicle charging stations). IssyGrid has connected more than a hundred homes, three commercial buildings, a dozen electric vehicles and smart streetlights in two streets in the neighbourhood. Several thousands of people contribute and participate in this testing ground by providing energy data. Getting inhabitants’ confidence on data protection is essential for the effi ciency of smart grids. Th e collect of energy data started in April 2015 with the agreement of public authorities. Data visualisation tools are now being developed as a basis for implementing communication actions.
Companies and individuals can control their consumption and avoid peaks in demand through monitoring on their mobile devices, remote management of their appliances, personalised recommendations, and display of financial savings. IssyGrid’s consortium partners, working to interconnect energy between items (electric vehicles, washing machines, air conditioning of large buildings, etc.), off er steering advice to occupants to optimise their energy costs and their environmental impact. A cloud-based service has also been deployed at the city level to inform end-users about their carbon efficiency and link them to future demand-response programs and multimodal transportation services.
