Renewable energy technologies are transforming utility operations in significant ways. Focused investment in solar, electric vehicles, and energy storage solutions has brought renewable technologies into the mainstream. After decades of resistance, utilities have started embracing these new technologies. For many utilities in developed markets, the deployment of these technologies creates a business imperative to improve sagging demand of electricity and hence long-term business sustainability. 

​

However, renewable technology integration creates large operational challenges. If not managed, these technologies can deteriorate the stability and reliability of electricity grids. Contrary to the belief that distributed generation can improve voltages in long distribution feeders, these technologies may create harmonics and stability issues in weak grids. Utilities need to understand the impacts of renewable technologies and design grids and integration to take advantage of clean and sustainable technologies. Utilities need to examine the resilience of their current grids and what is necessary to manage renewable integration.
