The biggest challenge in the use of renewable and non-renewable energy sources lies in preventing power grid imbalances. When there is an abundance of sustainable energy, this should be tapped into to meet energy demand instead of centrally transmitted energy. However, there is no incentive for consumers to maximize their use of renewable energy sources without insight into energy supply and demand and related price fluctuations.
To limit power grid imbalances, CGI developed a Central Energy Management System (CEMS) for smart grids. CEMS is connected to home energy computers and provides residents with up-to-date energy information, such as current energy prices, supply and demand, weather forecasts, etc. It’s also linked to various smart devices in the home, such as solar panels, smart energy meters, electric car charging points and smart devices for appliances such as washing machines.
Residents can use the information provided by CEMS to make better choices with regard to their energy consumption. They can know when supply is high and prices are low and vice versa, helping them to use the right energy resources at the right time. For example, they can set their smart washing machines to start automatically when electricity prices are low or tap into solar generated energy when electricity prices are high.
CEMS offers the following features:
CEMS is compatible with the smart grid technology that is on the rise in many countries. Smart grids enable grid operators to increase flexibility in demand and better anticipate fast-changing energy flows.
CGI is a forerunner in the field of smart grids, delivering insight, foresight and innovative solutions for the generation and consumption of sustainable energy. CGI’s approach to smart energy is a combination of having a vision and putting that vision into practice. We take into account both the environment and costs in developing smart grid strategies, solutions and services, ensuring the right balance among each. We also offer open protocols to facilitate the integration of smart grid technologies and cloud services that allow clients to pay only for what they use.
Examples of our smart grid work include the following:
