Avantus has closed a $1.05 billion upsized corporate credit facility, more than doubling its previous $522 million line, to fund a massive pipeline of solar and storage projects in California and the Desert Southwest. The expanded financing is set to accelerate Avantus’s transition into an independent power producer (IPP) model and the advancement of 24 GW of solar and 44 GWh of battery storage projects.

The credit facility terms
This transaction adds substantial financial flexibility for Avantus, extending its corporate financing capacity from $522 million, previously secured in July 2024, to $1.05 billion. Syndicated by a mixture of existing and new institutional lenders, the credit facility provides the capital runway needed for multi-year development plans.
SMBC led as Administrative Agent, Collateral Agent, and Lead Arranger. The group of returning lead arrangers included ING Capital LLC, HSBC, KKR, and Truist Securities. The syndicate was expanded by six new lead arrangers: BHI (Bank Hapoalim), CIBC, KeyBanc Capital Markets, Mizuho, National Bank of Canada Capital Markets, and Natixis Corporate & Investment Banking.
Kirkland & Ellis advised Avantus on legal aspects, while Milbank LLP represented the lender consortium. KKR Capital Markets and EIG Capital Markets acted as placement agents, indicating ongoing strong institutional interest in the company and the region’s clean energy transition.
The negotiation and stacking of this enlarged facility signal robust lender confidence in Avantus’s project pipeline strategy, as suited to scale in current market conditions marked by elevated project finance demand and developer competition for capital.
Pipeline focus and market geography
The $1.05 billion facility is dedicated to progressing a 24 GW pipeline across Avantus’s core geographies in California and the Desert Southwest. The focus aligns with these states’ aggressive renewable energy mandates, strong corporate procurement activity, and high grid demand for dispatchable capacity solutions.
Avantus’s stated pipeline comprises 13 GW of solar photovoltaic generation coupled with 44 GWh of battery energy storage systems (BESS), reflecting a strategy to pair nearly all large utility-scale solar assets with storage for grid services and load shaping. The region faces pronounced solar capacity saturation risks and increasing curtailments, making battery integration crucial for project economics.
Recent delivery milestones include the online commissioning of Aratina 1, a 200 MW solar and 500 MWh storage facility in Kern County, California. The developer has also secured over $525 million in construction debt for Aratina 2, the adjacent build, and a 20-year PPA for the 200 MW/800 MWh Rexford 2 project in Tulare County, underscoring sustained offtake appetite from utilities and other bulk buyers in central California.
This geographic placement leverages wholesale market volatility, locational marginal pricing opportunities, and Resource Adequacy incentives, all of which are key market factors for investors evaluating risk-adjusted returns from new solar-plus-storage assets.
Transition to independent power producer
Avantus’s move to become an independent power producer is closely tied to this upsized facility, as larger and longer-term financing is required for holding merchant or contracted assets on balance sheet. The credit package explicitly supports bringing 788 MW into commercial operation and maintaining 800 MW under active construction through 2026.
This shift positions Avantus to capture additional project value through the development, construction, and operational phases. Holding assets as an IPP, rather than immediately selling projects upon NTP (Notice to Proceed), reflects a response to deepening institutional investor pools seeking stable, operating infrastructure assets with recurring cash flows.
By scaling as an IPP, Avantus can also optimize project timing relative to market signals, hedge against potential offtake or regulatory variability, and capture volatility-driven upside, particularly in California’s rapidly evolving capacity markets. The strategy aligns with broader developer moves across the market, as evidenced by similar transitions among vertically integrating players.
Institutional investor dynamics
The lender syndicate backing this facility highlights broad and deep institutional appetite for large-scale renewables and storage assets. Notably, sponsors KKR and EIG remain closely involved, signaling continued alignment with private equity objectives targeting decarbonization, yield, and inflation-resilient investment themes.
Lead arranging by commercial banks and capital markets participation from KKR and EIG indicate continued evolution in specialized energy project financing. By structuring the transaction as a corporate credit facility, rather than traditional project-level non-recourse debt, Avantus gains the agility for programmatic deployment of capital across a portfolio, responsive to shifting interconnection, permitting, and supply chain timelines.
Legal and financial structuring, as evidenced by the choice of major law firms and lead agents, mirrors recent trends in utility-scale finance, where emphasis is placed on syndicate flexibility, covenant structures, and scalability as market reforms in California ISO and the Western EIM create new pricing regimes.
Development outlook through 2026
Avantus reports it is on track to have 788 MW in operation and keep 800 MW of assets under active construction by year-end 2026. With a total pipeline sized to serve over 10 million homes when complete, the capital secured via this credit package will support both shovel-ready and advanced-stage project delivery.
Project execution in this region will depend on continued access to interconnection, stable PPA pricing, and the ability to deliver storage-backed dispatchable capacity to the California ISO and Desert Southwest balancing authorities. Risks include interconnection queue congestion, commodity price fluctuations, and evolving regulatory requirements, all of which the financial strength from this facility is meant to help manage.
The development trajectory mirrors state and utility needs for new clean capacity to meet mid- and long-term Resource Adequacy targets as fossil retirements accelerate. Avantus’s step-up in financial firepower may enable it to compete more aggressively for load-serving entity contracts, and potentially serve emerging energy buyers such as data center and digital infrastructure operators in the region.
What this means for buyers
Institutional buyers and corporate offtakers can anticipate greater liquidity and optionality in California and Desert Southwest renewables markets as Avantus accelerates delivery. The expanded credit facility improves execution certainty for new solar and storage capacity and enhances competition for PPAs and capacity sales. For investors, the facility signals lender confidence in large-scale asset development, supporting more stable power procurement and contracting environments through 2026. Buyers should monitor project milestones and offtake opportunities as Avantus transitions assets from development to operation at scale.
