File Scaling Up Renewable Energy Generation: Aligning Targets and Incentives With Grid Integration Considerations
Countries around the world have established ambitious targets for increasing the contribution of renewable energy toward meeting their national energy demand. At low penetrations of wind and solar (e.g., below 5%–10% of annual electric demand), impacts to the power system are likely to be minimal. However, as the proportion of variable renewable energy (VRE) connected to the grid increases, power system planners will increasingly need to evaluate and manage the impact of increased variability and uncertainty on system operations. They will also need to ensure that the policy and regulatory environment offers sufficient certainty and revenue streams to encourage investment in new VRE generation. To address these needs, power system planners can take several steps to align targets and incentives with grid integration considerations.

File D source code Using Wind and Solar to Reliably Meet Electricity Demand
An important aspect of power system planning is ensuring that adequate generation capacity exists to meet electricity demand during all hours of the year. Mechanical failures, planned maintenance, or lack of on-demand generating resources (especially for variable renewable resources) may leave a power system with insufficient capacity to meet demand. Grid planners project future peak demand patterns and estimate the relative contribution of each generator towards achieving a reliable supply of energy. When generating during peak demand periods, variable renewable energy (VRE) such as wind or solar PV provides capacity value to the system. By providing capacity value, VRE can help to defer capital investments in traditional generation and transmission infrastructure.
