A Changing Energy World Utility-scale solar. Smart homes. Rooftop solar. Electric vehicles. Rapidly changing technologies, evolving consumer demand and decentralization affects the way that MISO and its stakeholders adapt to changes in generation, transmission and distribution. Decentralization, as a trend, will continue to transform the industry and the MISO footprint as it shifts away from its historical dependence on large, centralstation plants towards greater reliance on smaller and more geographically dispersed DERs. In response to stakeholder needs, MISO is currently exploring what increasing amounts of DERs mean for grid operations with high DER penetration, and learning more about issues by conducting workshops and listening to voices from across the transmission and distribution spectrum. DER can be organized into three primary technology categories: • Demand-side management, which may include energy efficiency measures, load-modifying resources and demand response (e.g., smart thermostats, large water pumps, variable-speed motors) or ways to control electric vehicle charging. This usually includes incentives to help shape the consumption of energy from the grid to provide value to the end user and/or to the grid. • Distributed generation, which is generation connected to the distribution grid. It may be infront-of or behind the meter, and may be used to reduce customer net load or to provide energy or services sold into the grid. DERs are power generation, storage, or demand-side management connected to the electrical system, either behind the meter on a customer’s premises, or on a utility’s distribution system. • Distributed storage, which is customer or utility/ third-party-owned resources, located on the distribution system or behind the customer meter, that can withdraw energy for later use or injection into the grid.
