Key Insight

Risk Management

Rising PPA Prices Across ISOs

Higher VPPA offer prices across the board show generally negative modeled economics across the U.S. as a whole, with ERCOT showing some but limited bright spots.

With rising VPPA offer prices, buyers planning to transact in a VPPA should act with intention. NZCB procurements still prove to beat market benchmarks on price and terms.

Corporate Clean Energy Deal Flow Remains Active

The corporate clean energy market is growing. In Q1 2026, CEBA announced 13.4 GW of corporate clean energy deals. This is ahead of 2025, which announced 11.3 GW of deals by Q2 2025. In 2025, 27.3 GW of energy deals were announced, up 12% from 2024. 70%+ of capacity announced in CY2025 involved solar.

Competition from hyperscalers for limited capacity often prices out individual non-hyperscale buyers.

Joining the NZCB allows non-hyperscalers to enter the market at scale by aggregating demand across multiple high-credit buyers.

Sustained Electricity Demand Surge & Electricity Prices Trending Higher

EIA forecasts strongest 4-year electricity demand growth since 2000; U.S. data center demand projected to reach 75.8 GW in 2026.

The EIA’s April 2026 Short-Term Energy Outlook forecasts Henry Hub spot prices averaging $3.67/MMBtu (dollars per million Btu) in 2026, up from $3.53/MMBtu in 2025 and $2.19/MMBtu in 2024.

Upward pressure on VPPA prices and electricity market prices are prevalent. VPPAs can act as a hedge against upward trending electricity prices, especially when the impacts of the war and other drivers for electricity growth, including AI. electrification, and data centers, have not yet been fully felt.

Iran War Shapes Global Energy Risk

Globally, since the Iran War broke out, the World Bank projects energy prices to be 24% higher in 2026 – a four-year high – with Brent averaging $86/bbl and a high price scenario of $115/bbl.

Research shows that electricity prices are trending higher. EIA’s 2026 Electricity Forecast predicted average U.S. wholesale power prices to rise to about $51/MWh in 2026, roughly 8.5% higher than 2025.

The war’s impact on electricity prices in the U.S. has not yet been felt compared to other countries, but wholesale electricity prices have generally risen in Q1 2026 due to extreme weather and continued demand growth.

Demand growth is happening concurrently with new capacity coming online. This fundamentally changes the shape of electricity generation and price fluctuations, further detailed in this quarter’s Opportunity Index.

Tax Credit Cliff: July 4, 2026

The 2025 Budget Reconciliation Bill beginning-of-construction deadline is approaching.

Many top developers have successfully long safe harbored components that comply with the beginning of construction guidelines and deadline which is now three months away.

Projects qualifying for full tax credits are shrinking, but the NZCB is selective to projects with successfully safe harbored materials for future projects. Post-deadline and non-tax-credit-secured project pricing will be higher and therefore score lower on NZCB’s Five Level Risk Ranking.

Standards Inflection

Greenhouse Gas Protocol (GHGP) second Scope 2 consultation expected in 2026, with final publication expected late 2027. SBTi Corporate Net Zero Standard (CNZS) V2.0 is in review in 2026; new guidance will be in effect and mandatory from January 1, 2028 onwards.

Tim Mohin has been appointed CEO of GHGP as of April 2026.

Most SR Inc Member Client organizations are staying on path with their emissions-first decarbonization goals, while a few leading companies are beginning to explore potential alignment with 24/7 hourly and geographic matching.

Tim Mohin’s role as CEO, and substantial corporate experience, will be pivotal to shaping the direction of GHGP revisions.

Key Market Themes

1. Corporate Clean Energy Deal Flow Grows in Q1 2026

Corporate clean energy deal flow remains robust. In Q1 2026, 13.4 GW of capacity was announced, outpacing the 11.3 GW recorded by early 2025. This follows a record-setting 2025, where 27.3 GW of deals were closed—a 12% increase from 2024. Solar represented over 70% of 2025 volume, while clean firm power—encompassing nuclear, geothermal, hydro, and natural gas with CCS—accounted for 65% of total clean firm capacity additions.

The market continues to consolidate, with 40% fewer participants than in 2024 and new entrants reaching a decade-low. Hyperscalers like Google and Meta dominated ERCOT, accounting for roughly 80% of volume and highlighting the challenge for individual buyers. NZCB’s aggregation model remains essential for mid-market buyers to secure supply and pricing terms that would otherwise be reserved for hyperscale-level commitments.

2. VPPA Prices at Record Highs

VPPA offer prices reached record levels in Q1 2026, with wind and solar rising 17% and 3% respectively over the prior year. Developers point to structural headwinds—including component tariffs, insurance premiums, labor shortages, and federal permitting constraints—suggesting these higher costs are unlikely to reverse.

While SR Inc’s modeling shows ERCOT and SPP South solar as relative bright spots for breakeven cashflow, standard 10MW offtakes generally produced negative modeled economics this quarter. NZCB’s market-wide pricing intelligence is critical for identifying cost-competitive projects as offer prices increasingly diverge from execution realities.

3. Federal Policy Headwinds and the Renewable Energy Reality

Despite headlines regarding the Trump administration’s efforts to slow federal approvals for renewables, actual grid additions remain at historic highs. In 2025, the U.S. added 53 GW of new capacity—the most since 2002—with solar and battery storage together accounting for nearly 80% of those additions.

The EIA projects a 60% increase in utility-scale solar for 2026, targeting 43.4 GW. To mitigate policy risk, NZCB’s selection framework prioritizes projects that avoid federal land and authority exposure, applying rigorous vetting through SR Inc’s Five Level Risk Ranking.

4. Tax Credit Countdown: July 4, 2026

The Budget Reconciliation Bill’s July 4, 2026 construction deadline is now less than three months away. Tighter IRS criteria regarding supply chain origins have further reduced the pool of qualifying projects.

As developers sideline projects that cannot meet these requirements, capacity qualifying for full tax credits is commanding a significant premium. SR Inc continues to vet and secure the narrowing pool of tax-credit-advantaged opportunities for NZCB participants.

5. The Iran War and Electricity Price Risk

The Iran War and the closure of the Strait of Hormuz have significantly impacted global energy risk, driving Brent crude up 55%. The World Bank projects global energy prices will reach a four-year high in 2026, with manufacturing surcharges and record-high metal prices already impacting supply chains.

While the war’s full impact on U.S. electricity prices has yet to be felt, structural demand from AI, data centers, and electrification will sustain upward pressure. VPPAs remain a vital hedge against this volatility, as long-run demand forces continue to reshape the market environment.

6. Evolving Standards: GHGP and SBTi

Revisions to the Greenhouse Gas Protocol (GHGP) and the SBTi Corporate Net Zero Standard are advancing, with final publications and mandatory adoption expected between 2027 and 2028. Both organizations are evaluating legacy provisions for existing market-based instruments.

The appointment of Tim Mohin as GHGP’s first CEO brings a corporate-aligned perspective to the standards process. SR Inc maintains that causation—or consequential accounting—is the most defensible approach for evaluating VPPA impact, ensuring NZCB members are well-positioned regardless of the final revisions.

Electricity Market Trends

Renewable Capacity Additions

Solar continues to dominate new U.S. generation capacity additions. The EIA forecasts solar generation to increase 21% in both 2026 and 2027. The U.S. solar industry installed 43.2 GW of capacity in 2025, and developers plan to add 43.4 GW in 2026 — a 60% increase in annual additions if realized. 40% of planned new utility-scale solar capacity is in Texas.

Wind capacity installations rebounded in 2025, with 8.2 GW connected — up nearly 50% year-over-year following a decade-low in 2024. WoodMackenzie projects 2026 as potentially the best installation year for wind in five years, though federal policy headwinds and rising turbine prices continue to weigh on the longer-term pipeline. Battery storage hit a record 15 GW in 2025 and is increasingly co-located with new solar projects, with 24 GW of utility-scale storage anticipated in 2026.

Electricity Demand Outlook

U.S. electricity demand is entering what the EIA describes as its strongest four-year growth period since 2000, driven by data centers, AI infrastructure, and manufacturing expansion. As of early 2026, 48 GW of U.S. data center capacity was under construction or committed, with BNEF projecting demand to reach 106 GW by 2035. Data center electricity demand has grown more than 400% over the past decade.

ERCOT’s Long-Term Forecast for 2026–2032 shows a baseline of 2–3% annual growth and a high-scenario forecast of over 20% annually, with more realistic third-party estimates at 5–6% — enough to more than double the ERCOT market within the term of a newly executed VPPA. In PJM, electricity demand from data center growth is projected to grow up to 30 GW between 2025 and 2030. These dynamics create sustained upward pressure on electricity prices and underscore the long-run hedging value of VPPA structures.

Q1 2026 VPPA Market

Wind and solar VPPA prices reached record highs in Q1 2026, continuing a trajectory of escalation since 2022. The primary cost drivers — tariffs, rising insurance premiums, labor shortages, and federal permitting constraints — are structural supply-side pressures unlikely to reverse in the near term. Simultaneously, ITC/PTC-applicable project constraints are reducing the effective supply of qualifying projects available for buyer offtake, as developers preserve tax credit eligibility for their strongest pipeline projects while sidelining others.

Big-tech competition for renewable energy capacity remains a defining dynamic. Google and Meta accounted for 80% of ERCOT PPA volumes in Q1 2026. Google, Microsoft, Meta, and Amazon continue to execute large-scale VPPAs and, in some cases, are acquiring renewable developers outright to secure generation capacity. NZCB’s reverse auction structure provides participants with aggregated market leverage — closing the gap between mid-market buyers and hyperscalers in terms of pricing power and project access.

SR Inc’s Q1 2026 analysis of Purchaser-Caused EAC (PC EAC) costs shows that the average modeled cost of VPPA-sourced EACs rose to $19.60 per PC EAC in Q1 2026, up from $16.04 in Q1 2025. These figures reflect market offer prices, not SR Inc procurement results. NZCB procurements consistently achieve meaningfully better pricing through SR Inc’s professionally managed reverse auction process.

Quantitative Analysis

To better quantify U.S. VPPA market dynamics, the NZCB has published the NZCB VPPA Opportunity Index quarterly since 2019 to help advance SR Inc’s mission to accelerate the development and adoption of best practices in more sustainable business. The NZCB VPPA Opportunity Index enables comparison of potential wind and solar VPPA performance across U.S. hubs using common analytics. Based on proprietary SR Inc analytics and data from LevelTen Energy and REsurety, it reflects both prior actual (backcast) performance and carefully modeled forward pricing. Noteworthily, the Index is based upon VPPA offers (which NZCB participants view as “marketing prices”), not executed transactions (which include multiple buyer-favorable protections), made over the prior quarter.

  1. Top quartile offered wind VPPA prices across the country were up 17% on average from the previous 12 months, while offered solar VPPA prices were up 3%.
  2. Realized electricity prices have remained low but increased from the prior year. Average trailing 12-month (TTM) realized wind electricity prices in Q1 2026 were up 5% (to $23.14) across active hubs from the TTM in Q1 2025 and realized solar electricity prices were up 22% (to $37.41) from Q1 2025.
  3. The combination of higher VPPA prices and higher realized prices caused expected cashflows in the TTM for a 10MW wind VPPA to drop $291K from Q1 2025 to Q1 2026 (to negative $1.3M) and increase $31K (to negative $728K) for a 10MW solar VPPA.
  4. Our longer-term view Opportunity Index shows that average modeled cashflow through Q1 2041 per 10MW VPPA across active hubs decreased $8K in Q1 (to negative $774K) versus Q4 2025 for wind and decreased $16K (to negative $414K) for solar.
  5. In Q1, wind VPPAs modeled to be less expensive in none of active hubs versus buying reputationally riskier unbundled EACs (based on the typical average cost today of $2.92 for a 10-year strip of unbundled EACs as of April 2026), and solar VPPAs modeled to be less expensive in 13% of all hubs.
  6. The average modeled hub annual cashflow for a 10MW wind VPPA would have been $879K more expensive than buying the equivalent number of reputationally riskier multi-year unbundled EAC strips, and the average modeled hub annual cashflow for a 10MW solar VPPA would have been $484K more expensive.
  7. Price modeling shows that ERCOT solar and SPP South solar presented the best modeled opportunities for breakeven cashflow in Q1. The average modeled annual cashflow for a 10MW ERCOT solar VPPA was negative $81K and negative $53K for SPP South solar.
  8. For wind, price modeling continued to show that ERCOT South presented the best modeled opportunity in Q1, which was negative $498K per 10MW VPPA.
  9. To underscore the importance of NZCB’s procurement process, active 2026 Q1 NZCB procurements for PC EACs for to-be-built solar were below the Q1 P25 VPPA prices for the same hubs, despite also providing more than a dozen specially sought and secured buyer-favorable risk management terms required by risk-averse, environmentally motivated corporate procurement teams.

The NZCB VPPA Opportunity Index intentionally simplifies complex markets. Nevertheless, many NZCB participants find the rendering helps them begin to understand the market dynamics and financial implications of VPPA-based renewable energy strategies.

When NZCB participants wish to pursue specific VPPA opportunities, SR Inc offers stakeholder briefings and detailed, customized analytics before transacting. This bespoke financial, legal, and market expertise helps VPPA offtakers to develop a timely procurement strategy; implement the procurement strategy in an auditable way; and structure, contract, and negotiate the transaction in a buyer-favorable manner. SR Inc supports NZCB buyers throughout the corporate procurement process, helping them navigate rapidly changing markets such as the one we are in today.

 

About the NZCB

The Net Zero Consortium for Buyers (NZCB) is a buy-side-only procurement consortium operated by SR Inc, designed to give corporate buyers access to utility-scale renewable energy procurement on terms previously available only to large utilities and hyperscale technology companies. NZCB members benefit from aggregated purchasing scale, SR Inc’s reverse auction structure (which consistently produces below-market pricing), and SR Inc’s buy-side-only advisory model, ensuring that every recommendation reflects the interests of corporate buyers.

Through NZCB, companies with 10 MW or more of individual offtake capacity in a given market can participate in transactions that deliver premium pricing, project quality, and contractual protections. SR Inc’s VPPA 2.0 model democratizes access to this procurement pathway for mid-market and large corporate buyers. NZCB’s reverse auction process creates competition among developers bidding for member offtake, resulting in pricing that beats market benchmarks quarter after quarter.
