The transition to renewable energy could lead to a 30-60% decrease in electricity prices across parts of Europe by 2026, according to an optimistic forecast by analysts Emmanuel Dubois-Pelerin and Massimo Schiavo at S&P Global Ratings. However, the prediction comes with caveats, as the shift to renewables faces risks that could impact the scale and pace of price declines.
- Analysts forecast a plunge in electricity prices by 2026 as renewables offset coal and nuclear phase-outs.
- But the transition timeline and price impacts vary significantly by region.
- Infrastructure constraints, permitting delays, and inflexible demand could limit price drops.
Renewable Growth Outpacing Demand
Across Europe, wind and solar capacity is expected to triple by 2030, reaching 780 GW and 370 GW respectively. This renewable boom will outpace rising electricity demand, diminishing the influence of high-cost natural gas in many markets.
Specifically, S&P Global Commodity Insights estimates renewable energy’s share of the energy mix will rise to 55% by 2030, up from 20% in 2021. In contrast, fossil fuels’ contribution will plunge from 33% to 10% over the same period.
Several factors are catalyzing this rapid growth in renewable generation capacity:
- Government incentives and policy support for wind and solar development
- Improving cost-competitiveness of renewables vs traditional energy sources
- Corporate renewables procurement driving additional capacity builds
- investor appetite for green energy investments
As renewable supplies surge, the marginal cost of generating electricity from wind and solar will become cheaper than legacy fossil fuel plants, leading to more cost-effective electricity prices.
Regional Disparities in Pace and Price Impacts
While the outlook is positive overall, the shift to renewables is progressing faster in Northern Europe compared to Southern countries.
Germany, France, and the UK are retiring coal plants and nuclear facilities at a quicker pace while rapidly permitting new wind farms, especially offshore capacity. Southern nations like Italy, Spain, and Greece have been slower to install new renewable generation.
These regional disparities mean electricity price decreases resulting from added renewable supplies may be more modest in Southern Europe by 2026 compared to Northern markets. Italy in particular may lag due to its heavier dependence on natural gas and slower buildout of wind and solar capacity compared to European leaders like Germany.
Challenges Facing the Energy Transition
While the outlook is optimistic overall, several factors could constrain the fall in electricity prices:
Permitting and Grid Connection Bottlenecks
Connecting massive new wind and solar facilities will require regulatory approval and transmission infrastructure upgrades. Permitting bottlenecks or delays in grid enhancements could slow the pace of new projects coming online.
Insufficient Transmission Infrastructure
Seamlessly integrating surging renewable supplies will require expanded cross-border interconnections between national grids, allowing flexibility to balance variable wind and solar resources across regions. Upgrades to internal transmission systems are also needed in many markets.
Lagging Energy Storage Investments
Energy storage like battery installations will play a key role in balancing intermittent renewable generation. But some markets have seen lackluster investment in storage, which could hamper renewable integration.
Inflexible Electricity Demand
Optimizing renewable supplies requires flexibility in electricity consumption, with usage surging during sunny and windy periods and receding during lulls. Slow adoption of smart grid technologies and demand response capabilities could constrain these demand fluctuations.
Policy and Regulatory Uncertainty
While renewable energy targets are expanding, policy uncertainty around long-term incentives and changing regulations could discourage new projects. For example, retrospective changes to feed-in tariffs have disrupted solar growth in some markets.
High Capital Costs
Despite improving cost-competitiveness, wind and solar projects require significant upfront capital. Rising interest rates and potential shifts in access to finance could impact project development.
Benefits of Transitioning to Renewables
While risks remain, successfully executing an accelerated transition to renewables can provide substantial economic and environmental benefits:
- Lower wholesale electricity prices, reducing costs for consumers and businesses
- Enhanced energy security by relying on domestically produced renewable energy rather than imported fossil fuels
- Reduced exposure to global commodity price volatility
- Significant cuts in carbon emissions and air pollution from the power sector
The Bottom Line
The renewable energy boom provides hope for more affordable, sustainable electricity generation. But regional differences, infrastructure needs, and shifting market conditions must be navigated to fully realize the cost-saving and environmental potential. Progress will depend on strategic policy, grid investments, flexible demand, and innovative market design. While uncertainties exist, the energy transition offers immense possibilities.
