What are the challenges of integrating wind and solar PV into power systems?

We analyze three major challenges of integrating wind and solar PV into power systems. These are a low capacity credit, reduced utilization of dispatchable plants and over-production. All integration challenges increase with penetration, irrespective of mix and region.

What are the biggest challenges facing solar and wind?

Integrating Solar and Wind: Global experience and emerging challenges, published today, explores one of the biggest hurdles for policy makers as clean energy transitions gather speed. Between 2018 and 2023, solar PV and wind capacity worldwide more than doubled, and their share of electricity generation nearly doubled.

What are the integration challenges of solar PV?

All integration challenges increase with penetration independently of mix and region. Some challenges, namely the over-production and the increasing reduction of the utilization of baseload plants, increase stronger for high shares of solar PV (>20%). At low penetrations, solar PV is much easier to integrate in the US than in Germany.

Excess solar and wind energy can be curtailed due to no available storage. 100% reliability results if the solar and wind power supply system can meet all the electricity demand in every hour of the simulation.

When will wind and solar PV projects become operational?

Looking at the project pipeline through 2025, almost one-third of wind and solar PV projects are already contracted and/or financed. Those have limited risk of cancellation and thus are expected to become operational in 2020 and 2021, with some facing further delays carrying over to 2022 or beyond. IEA. Licence: CC BY 4.0
