The Economics of Distributed Renewable Power — Why We Should Democratize the Electricity System, Part 2

The Economics of Distributed Renewable Power — Why We Should Democratize the Electricity System, Part 2

Not all costs are covered in this levelized cost comparison.A grid with majority renewable power (from variable sources like wind and solar) will require a different approach than the existing grid. Whereas current generation scheduling, peaking and backup are tailored to a system with large, centralized baseload power plants, a grid with distributed renewable resources will require new load balancing ingenuity.It will be necessary to use smart grid technologies to enable greater demand response and to defer elective electricity use (such as electric vehicle charging) to times with greater supply, and to use energy storage like pumped hydro or batteries to shift surplus production to times of higher demand.It’s also a question of whether any additional costs incurred would be offset by other economic benefits.These issues are discussed later in this report.
