Private equity investments in renewable energy are evolving, driven by policy changes, demand from AI and data centers, and a focus on hybrid solar-plus-storage projects. Here’s what you need to know:
2025 saw fewer renewable M&A deals (109 deals worth $12.85 billion vs. 145 deals worth $18.15 billion in 2024), but valuations remained steady, with TEV/EBITDA multiples slightly increasing to 10.73x.
Operational assets are in high demand due to their stable returns, while early-stage projects face challenges from tighter tax credit deadlines under the "One Big Beautiful Bill Act" (OBBBA).
Hybrid solar-plus-storage projects are a priority for private equity, addressing grid stability issues and meeting the growing power needs of AI and data centers.
Policy shifts like OBBBA have increased costs for new solar and wind projects by 36%-63%, creating hurdles for early-stage developments.
State-level rollbacks in renewable portfolio standards (RPS) are impacting valuations in regions pulling back on clean energy commitments.
Private equity firms are consolidating by acquiring developers with operational projects and late-stage pipelines, focusing on assets backed by long-term Power Purchase Agreements (PPAs).
Key takeaway: Private equity is prioritizing stable, de-risked renewable energy assets, with hybrid solar-plus-storage projects and operational portfolios leading the way. Investors are adapting to policy changes and market demands, creating opportunities for businesses with strong fundamentals.
How U.S. Policy Changes Affect Renewable Energy Valuations
The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, has reshaped how renewable energy projects are valued. This legislation introduced tighter tax credit deadlines, creating significant pressure on project timelines and margins. Wind and solar projects, for instance, must prove construction started by July 4, 2026, to qualify for 100% federal tax credits. Any projects starting after this date must be operational by December 31, 2027, to avoid losing eligibility altogether [5][6].
This policy shift has already had a chilling effect on investments. In the first half of 2025 alone, over $20 billion in clean energy projects were canceled, with solar, storage, and hydrogen projects accounting for about $2 billion in cancellations during Q3 [6][7].
"The OBBBA has fundamentally rewritten the economics of renewable energy development, with solar and wind projects facing a cliff of this support", said AlixPartners [6].
Federal Tax Credit Phaseouts and Safe-Harbor Deadlines
The OBBBA also removed a key planning tool for developers. IRS Notice 2025-42 eliminated the "5% safe harbor" provision for most wind and solar projects starting on or after September 2, 2025. Developers now have to meet the "Physical Work Test", which requires evidence of on-site construction activity - like excavation or racking installation - to qualify for tax credits [5][8]. Only small solar facilities with a maximum net output of 1.5 MW or less are still allowed to use the 5% safe harbor [5][8].
Adding to the complexity, new rules around Prohibited Foreign Entity (PFE) and Foreign Entity of Concern (FEOC) impose cost ratio thresholds for projects starting after December 31, 2025. These regulations, aimed at reducing reliance on international supply chains, increase compliance costs and create valuation uncertainty. By late 2025, only 38% of firms surveyed felt "fully prepared" to meet these rules for 2026 [7].
The financial toll is significant. Tax credit phaseouts are expected to drive up solar project costs by 36% to 55%, while onshore wind costs could rise by 32% to 63% in the next year [10]. This cost surge compresses margins and reduces valuations, especially for projects in early development stages that can’t meet the July 2026 deadline.
These federal changes are compounded by varying state-level policies.
State Renewable Portfolio Standards Changes
While federal policies tighten, state-level shifts add another layer of complexity. For example, Ohio passed legislation in May 2025 to end its Renewable Portfolio Standard after 2026, citing concerns over electricity costs [10]. Similarly, North Carolina lawmakers overturned a gubernatorial veto in July 2025 to scrap the state’s 2030 carbon reduction target [10]. These rollbacks immediately reduce valuations for projects in affected states, as future revenue from Renewable Energy Certificates (RECs) becomes less certain.
The contrast between states is striking. In 2024, 28 states with RPS policies were responsible for 37% of renewable energy capacity additions [10]. However, the pace of growth has become uneven. States with strong or expanding mandates see higher REC prices and, consequently, higher project valuations. For instance, PJM Tier I REC prices climbed to $35/MWh by the end of 2023, while Solar RECs (SRECs) in New Jersey, Massachusetts, and Washington D.C. ranged from $200/MWh to $450/MWh [9]. Projects in these markets are far more attractive to investors than those in states pulling back from renewable commitments.
Private equity firms are adjusting their strategies in response to these legislative shifts. Many are focusing on "established platforms" - firms that combine operational projects with late-stage development pipelines - in states where policy support remains consistent [10]. This shift highlights how policy uncertainty has become as critical as technology risk in determining project valuations.
Private Equity Investment Strategies in Renewable Energy
Private equity (PE) firms are adjusting their approaches to navigate uncertainties driven by shifting policies, focusing on strategies that ensure operational stability and steady returns. A key approach involves acquiring established developers with operational assets and late-stage project pipelines. For instance, in May 2024, EQT acquired Sweden-based developer OX2 for $1.5 billion, securing a 34 GW pipeline of solar, wind, and battery projects across Europe. This deal, valued at 19 times the last twelve months' EBITDA, highlights the appeal of privatization. By taking companies private, PE firms can focus on long-term growth strategies without the quarterly pressures of public markets.
This consolidation trend aligns with a growing preference for assets backed by long-term Power Purchase Agreements (PPAs). These agreements provide predictable cash flows, reducing risk and supporting higher valuations, even in uncertain policy environments. A notable example is the $6.2 billion institutional buyout of ALLETE by the Canada Pension Plan Investment Board and Global Infrastructure Partners in May 2024, one of the year's largest renewable-focused private equity transactions. Additionally, investors are increasingly comfortable with construction risk, a bold strategy that was uncommon a decade ago.
"As long as markets are concerned about possible short-term obstacles for renewables stocks, private equity investors will take the opportunity to take them private and maintain a buy-and-build strategy", said an Associate Director at Warburg Research [11].
The numbers speak for themselves: renewable energy mergers and acquisitions hit a record $117 billion in 2024, with private equity accounting for over $60 billion of that total. This intense competition for high-quality assets is driving valuations upward, compelling firms to refine their strategies.
Hybrid Solar-Storage Project Investments
Hybrid solar-storage projects are becoming a hot spot for private equity investment. These projects combine solar power generation with battery storage, addressing renewable energy's intermittency while unlocking multiple revenue streams. A major driver behind this trend is the rising demand from data centers. The rapid growth of AI and data centers has created a need for reliable, around-the-clock clean energy, which hybrid projects can deliver. In December 2024, Google and TPG Rise Climate partnered with Intersect Power on a $20 billion initiative to develop renewable-powered data centers, co-locating clean energy generation with data center operations to enhance reliability.
Battery storage offers flexibility through incremental deployment. This modular approach allows investors to scale projects based on changing market conditions and costs, mitigating upfront risks. Solar and storage assets also benefit from zero fuel costs and lower operating expenses, making them an attractive long-term investment.
"You can build one [battery storage unit], then maybe you see the cost has come down and build the next one larger... So, you can revise your strategy over time, and that's really helpful", said Igor Makar, Member of Management, Private Infrastructure, at Partners Group [3].
The financial advantages are clear. In 2023, the global levelized cost of electricity (LCOE) for solar PV was 56% lower than fossil fuel alternatives. Between August 2022 and February 2023, private equity investments in combined renewables reached $20.9 billion. By the end of 2024, the U.S. had installed 32 GW of energy storage capacity. These projects not only diversify income streams but also pave the way for innovative strategies like energy storage arbitrage.
Energy Storage Arbitrage for Portfolio Growth
Energy storage arbitrage is gaining traction as a strategy for optimizing portfolio returns. The concept is simple: charge batteries when electricity prices are low and discharge them during peak pricing periods. This approach decouples energy generation from consumption, allowing investors to sell power at premium prices. Storage assets also act as a hedge for renewable portfolios, helping to stabilize price fluctuations between low- and high-demand hours.
In 2024, energy storage installations grew by over 75% year-over-year in terms of megawatt-hours. Private equity deals focused on energy storage saw a 112% increase in value in Q1 2024 compared to the same period in 2023, totaling $1.4 billion. Notable investments include BlackRock's $500 million commitment to Recurrent Energy in January 2024 and the $1.091 billion investment by Infracapital Partners and KKR in Zenobe Energy to expand battery storage and electric vehicle capabilities.
"For other investors, these solutions are viewed as a hedge on traditional renewable portfolios aimed at normalizing the spreads between low- and high-priced hours", according to Morgan Lewis [12].
Integrating storage into investment portfolios strengthens financial resilience by addressing grid constraints and smoothing out renewable energy's intermittency. Onsite storage ensures a steady supply of clean energy during disruptions, enhancing reliability and competitiveness. Interestingly, private equity-owned companies often triple their renewable energy use within two years of acquisition, demonstrating the transformative impact of these strategies.
Current Valuation Trends and Metrics
The rapid expansion of AI-driven data centers has significantly increased U.S. power demands, giving renewable energy providers a stronger position in the market. Between 2020 and 2024, power requirements for U.S. data centers surged from 20 GW to 40 GW, with projections pointing to 81 GW by 2028. Hyperscalers now dominate about 75% of the U.S. corporate electricity off-take market, which has led to higher PPA (Power Purchase Agreement) prices and increased valuations. By 2025, data center operators faced PPA price hikes of up to 4% to secure access to carbon-free energy.
"Data centers come in with an urgent need of additional electricity and they're not very price-sensitive. So, they're going to put pressure on outdated grids and make an already tight power market even tighter, leading to higher prices", said Roman Boner, CFA, Senior Portfolio Manager, Robeco [3].
Assets tied to long-term PPAs are seeing higher valuations due to their predictable cash flows, even in uncertain regulatory environments. Platform acquisitions - those involving companies with both operational projects and late-stage pipelines - saw a 4.6x increase in value during 2025 as investors prioritized scale and expertise [10]. Key deals included TPG's $2.2 billion purchase of Altus Power and Brookfield Asset Management's $1.7 billion acquisition of National Grid Renewables, both in 2025 [10][16]. This trend highlights growing opportunities for recontracting existing renewable assets.
Data Center Demand and Recontracting Effects on Valuations
The rising demand for reliable, immediate power from data centers is boosting valuations for projects capable of meeting these needs. Hybrid solar-plus-storage projects are particularly sought after, as they provide 24/7 power while helping operators avoid new regulatory challenges. In December 2024, Google and TPG Rise Climate announced a $20 billion partnership with Intersect Power, aimed at co-locating data center operations with clean power generation and storage to ensure consistent energy supply [1].
"The rising demand for reliable baseload power fueled by generative AI and the rapid expansion of data centers has become a key driver of industry growth... [it has] the potential to fundamentally upend established markets and shift the supplier/off-taker power dynamic", according to FTI Consulting [1].
Regionally, MISO is now outpacing ERCOT in transaction volume, driven by rapid data center expansion and the popularity of build-transfer agreements [4]. Globally, data center capital expenditures are expected to hit $1.7 trillion by 2030, underscoring the ongoing need for renewable energy infrastructure [13]. These recontracting trends are reshaping valuation dynamics, paving the way for a closer look at technology-specific metrics.
Valuation Metrics by Technology
Recontracting trends are redefining valuations, and technology-specific performance is separating market leaders from laggards. Solar-plus-storage systems are leading the charge, accounting for 83% of new U.S. capacity growth as battery costs dropped 61% from 2020 to 2025. Wind energy, however, is lagging, with only 19% projected growth, although repowering existing wind projects offers a promising opportunity to boost energy yields by up to 300% using current sites and grid connections [10][14][15].
Updated projections from OBBBA reflect a decline in annual capacity additions and rising costs:
Metric | Pre-OBBBA Projection (2026–2030) | Post-OBBBA Projection (2026–2030) |
Annual Capacity Additions (Solar, Wind, Storage) | 54 GW – 85 GW | 30 GW – 66 GW |
Solar Cost Impact | Baseline | 36% – 55% Increase |
Onshore Wind Cost Impact | Baseline | 32% – 63% Increase |
Storage Pipeline by 2030 | N/A | 187 GW |
Despite these challenges, renewable energy remains cost-competitive. Fixed-mount solar LCOE (Levelized Cost of Energy) ranges between $30 and $80 per MWh, compared to $61 to $126 per MWh for natural gas combined cycle plants [10]. Globally, the LCOE for solar PV in 2023 was 56% lower than fossil fuel-fired alternatives - a dramatic improvement from 2010, when solar PV was 414% more expensive [3]. These favorable economics continue to attract private equity, with renewable energy M&A hitting a record $117 billion in 2024, over $60 billion of which came from private equity investments [4].
2026 Market Outlook and M&A Activity
As we move into 2026, the renewable energy sector is regaining momentum, bolstered by stable valuations and supportive policy changes. Private equity (PE) firms are entering the year with a staggering $880 billion in available capital, or "dry powder", signaling optimism in the market. This renewed confidence is driven by clearer policies and recent rate cuts, with deal activity centering on hybrid solar-plus-storage projects and platform acquisitions [17][18].
"Clearer conditions and stabilizing policy are restoring confidence. With ample capital and significant backlog, private equity is positioned for an active deal market in the near term."Josh Smigel, Private Equity Leader at PwC US [17]
This shift from uncertainty to a more stable environment is creating opportunities for innovative deal structures and strategies.
Lower Mid-Market Leading the Way
A notable trend is the surge in activity within the lower mid-market sector, which consists of businesses with less than $25 million in EBITDA. These companies now account for approximately 70% of PE deal volume. Add-on acquisitions and platform strategies are particularly popular, focusing on projects backed by power purchase agreements (PPAs) and scalable management teams. Firms like GEF Capital Partners are actively targeting family- and founder-owned businesses in areas such as residential solar, energy efficiency, and distributed energy resources [18][19][10].
Bridging Valuation Gaps
To address valuation challenges, earnouts and rollover equity have become common tools. These mechanisms help bridge gaps by allowing sellers to benefit from future growth while reducing risk for buyers in a still-evolving policy landscape [18]. For renewable energy businesses, attracting investment increasingly depends on presenting a de-risked profile. This includes long-term contracts, realistic interconnection timelines, and operational reliability, rather than speculative development pipelines. Platform-level transactions remain a priority, as investors seek companies with the technical expertise and infrastructure to handle multiple projects efficiently [10][17].
What the Market Values in 2026
The market is favoring businesses that can deliver results quickly and have strong grid access, especially as demand from data centers continues to grow. For owners of lower mid-market renewable energy companies, working with specialized advisors can be key to maximizing value in this competitive environment. For instance, firms like God Bless Retirement provide certified valuations and expert M&A guidance tailored to businesses with EBITDA under $25 million.
With ample capital and a more stable policy environment, the renewable energy market in 2026 is poised for significant activity. Investors are focusing on companies that combine operational excellence with the ability to meet immediate demands, making this an opportune time for well-positioned businesses to seek partnerships or investment.
Conclusion
Private equity is reshaping how renewable energy assets are valued, with over $60 billion in corporate acquisitions in 2024 and a global record of $117 billion. This shift is fueled by supportive federal policies, growing data center demand, and a focus on hybrid solar-storage projects [4]. As highlighted earlier, valuations now prioritize operational reliability rather than speculative development pipelines. Private equity firms are also taking on early-stage risks, moving upstream to secure project pipelines and meet evolving power demands [3].
For lower mid-market sellers - those with EBITDA under $25 million - this environment presents unique opportunities. Investors are particularly drawn to platform acquisitions backed by long-term power purchase agreements and strong management teams. To maximize value, sellers must present a de-risked profile, highlighting factors like grid access, realistic interconnection timelines, and strategies that align with investor interest in integrated energy solutions [2].
In such a competitive market, expert guidance is crucial. Advisors with expertise in both renewable energy and private equity transactions can provide essential services like certified valuations, buyer sourcing, and strategic positioning. For family- and founder-owned renewable energy businesses, partnering with firms like God Bless Retirement - which specializes in M&A for companies under $25 million EBITDA - can open doors to private equity networks and offer professional support throughout the transaction process.
FAQs
How does OBBBA change renewable project valuations?
The OBBBA has significantly impacted how renewable energy projects are valued. By tightening the requirements for tax credit qualifications and eliminating the 'safe harbor' rule, it has introduced new challenges for developers.
Previously, the 'safe harbor' rule provided a safety net by allowing projects to qualify based on financial investments rather than physical construction start dates. This flexibility helped reduce risks tied to strict timelines. With its removal, uncertainties in project valuations have grown, leading to noticeable shifts across the renewable energy sector.
Why are operating assets priced higher than early-stage projects?
Operating assets tend to fetch higher prices because they provide reliable and consistent cash flows and come with a history of successful operations. This track record lowers risk, making them far more attractive to investors than early-stage projects, which often involve more uncertainty and hurdles during development.
What makes solar-plus-storage most attractive to private equity?
Solar-plus-storage grabs the attention of private equity firms because it combines immediate cash flow with long-term growth potential. Operating assets in this sector start generating revenue right away, while a robust pipeline of future projects keeps the momentum going. Plus, the integration of storage solutions solves the problem of renewable energy's intermittent nature, making these investments steadier and more appealing for the long haul.
