• Smart city technologies and solutions have exploded onto the global arena, capturing both the attention and budgets of cities worldwide. According to research reports, the global smart cities market, estimated at USD 529.55 billion in 2017, is forecasted to grow at a  CAGR of 24.21 percent and reach USD 1944.67 billion by the end of 2023. Among the factors contributing to this growth are the expanding population within cities, growing degree of urbanization, increasing telecom penetration, and rising adoption of AI and Internet of Things, which together are driving the demand for smart cities. In India particularly, the adoption of this technology is being fuelled by the ‘Smart Cities’ initiative which has been introduced by the government to transform the country’s urban governance capabilities. However, despite these various driving factors, Smart City building is no easy task with the government facing challenges in channelling finances to Smart Cities, building coordination among multiple stakeholders, retrofitting existing cities, and creating utility services to meet the energy demands. As a result, this segment is now in need of vendors that can bring innovative techniques and technologies to not only tackle these challenges but to also equip smart cities with more potential for energy conservation, operational savings, public safety, and improved resource management.
