Key Findings

  • 01VRE growth leads to reduced wholesale energy prices and lower capacity factors for thermal generators.
  • 02Traditional baseload generators are more vulnerable to these market shifts than flexible intermediate and peak-load generators.
  • 03VRE is already influencing temporal and geographic price patterns in areas with high VRE penetration.
  • 04Observed impacts on average annual wholesale prices have been modest to date, with natural gas price reductions being a primary driver of price declines since 2008.
  • 05VRE has had limited direct impact on thermal plant retirements so far.

Application

Design takeaway

When designing energy-related products or systems, anticipate and integrate strategies to manage price fluctuations and the changing operational landscape driven by variable renewable energy sources.

How to apply

When designing a new power generation facility or energy storage system, model its performance and economic projections under various VRE penetration scenarios and fluctuating wholesale market prices.

Project actions

  • 01When researching energy systems, consider how different energy sources interact and affect each other's economic viability.
  • 02Investigate how market forces, like price changes, can influence the design and adoption of new technologies.

Strengths & Limitations

Strengths

  • +Synthesizes a broad range of literature and data.
  • +Compares both future projections and historical evidence.

Limitations

The study's findings on historical impacts might underestimate future effects as VRE penetration grows. The focus on the US market may limit applicability to other regions with different grid structures and policies.

Reliability & validity

The reliability of the findings depends on the quality and consistency of the synthesized literature and data. Validity is supported by the comparison of multiple studies and data sources, but potential biases in the original research could affect overall validity.

Think critically

To what extent do the current market structures adequately incentivize the necessary grid modernization and flexibility required to fully integrate higher levels of VRE without compromising grid stability or affordability?

05

Design Principles

"Design for dynamic market conditions; anticipate and adapt to evolving energy generation mixes and their economic consequences."

Designers and engineers developing energy systems or products that interact with the grid must account for these evolving market conditions. Understanding how VRE influences pricing and asset viability is crucial for economic feasibility and strategic planning in the energy sector.

06

What This Means for Your Design

Adding more solar and wind power to the electricity grid makes electricity cheaper in wholesale markets and makes it harder for old-style power plants (like coal and gas) to make money.

How to use in your project

  • 1.Use this research to justify the need for innovative energy storage or grid management solutions by highlighting the economic challenges posed by VRE integration.
  • 2.Cite this paper when discussing the impact of renewable energy on market prices and the operational efficiency of traditional power generation.
