Banks, infrastructure funds, private-credit providers and institutional investors are financing standalone and co-located BESS at increasingly meaningful scale, but the structures behind those financings vary considerably. Recent transactions show lenders financing contracted capacity payments, tolling agreements, revenue floors, hybrid solar-plus-storage portfolios and selected merchant exposure. They also show that BESS financing is no longer simply a senior term loan. Construction debt, tax-credit bridges, guarantee facilities, letters of credit, portfolio facilities and refinancing packages can all sit within the same capital structure. [Explore BESS Project Financing ](https://www.financely.io/bess-project-financing-for-battery-storage-portfolios?ref=blog.financely.io) ## The BESS Project Finance Market Has Scaled Quickly European battery storage financing expanded sharply during 2025 and the first quarter of 2026\. Modo Energy tracked 82 European BESS financing, investment, acquisition and offtake transactions during 2025, compared with 25 in 2024\. Disclosed project-finance debt rose from approximately €1.4 billion to €6.1 billion. Standalone BESS represented 88% of the recorded deal count. Activity accelerated again in Q1 2026\. Modo tracked 53 European BESS capital-markets transactions representing approximately 11 GW across 19 countries. Project finance accounted for 32 deals and 7.3 GW. Across the 12 financing transactions where debt amounts were disclosed, approximately €3.1 billion of project-finance debt was announced. **82** European BESS deals tracked during 2025 **€6.1bn** Disclosed European BESS debt during 2025 **11 GW** BESS capacity represented by Q1 2026 European deals Those headline figures require some caution. Portfolio financings combining solar and batteries can inflate the amount described as BESS project finance because the published debt package may not allocate proceeds separately between technologies. Even after making that distinction, the direction is clear: utility-scale storage has progressed from a specialist infrastructure niche into a recognizable project-finance asset class. ## Recent BESS Project Finance Deals The strongest indication of how lenders currently underwrite battery storage comes from recently closed transactions. They show several different routes to bankability. ### Greenvolt Poland €218 Million Financing In August 2026, [Greenvolt secured €218 million of financing from UniCredit ](https://www.enerdata.net/publications/daily-energy-news/greenvolt-secures-financing-400-mw16-gwh-bess-projects-poland.html?ref=blog.financely.io)for the Ełk and Turośń battery projects in Poland. The two facilities total 400 MW / 1.6 GWh, with each project sized at 200 MW / 800 MWh. The financing package includes approximately €153 million of bridge facilities and a €65 million guarantee facility. The structure is noteworthy because it demonstrates that major BESS financings can require substantial contingent-credit capacity in addition to funded debt. Guarantees, letters of credit and bridge facilities can become material components of the overall financing rather than ancillary documentation arranged after the senior debt has been negotiated. ### R.Power Jedwabno PLN270 Million Project Finance In June 2026, [Erste Group and Siemens Financial Services financed R.Power's Jedwabno BESS ](https://www.erstegroup.com/en/news-media/press-releases/2026/06/05/erste-group-finances-landmark-battery-energy-storage-system-project-in-poland?ref=blog.financely.io)through an approximately PLN270 million, or roughly €64 million, club-deal project finance facility. The project is 150 MW / 300 MWh and benefits from a 17-year Polish capacity market contract together with a long-term optimization agreement. This is a textbook illustration of how contractual revenue support can convert a battery project from predominantly merchant exposure into a more conventional debt-underwriting case. The lender can model contracted capacity revenue alongside optimization income rather than relying entirely on future arbitrage and ancillary-service prices. ### Thorpe Marsh £594 Million Non-Recourse Financing Fidra Energy's Thorpe Marsh project in Yorkshire represents one of the clearest demonstrations that very large batteries can now attract syndicated non-recourse debt. In 2025, [the 1.4 GW / approximately 3.1 GWh project secured about £595 million of debt ](https://www.sc.com/uk/?p=5219&ref=blog.financely.io). ABN AMRO separately described the financing as approximately £594 million of non-recourse project financing. The lender group included a broad consortium of international commercial banks. Sponsor-side capital included EIG and the UK's National Wealth Fund. Thorpe Marsh matters for the wider market because syndication at this scale demonstrates that BESS lender appetite is no longer restricted to small bilateral facilities. Large projects with strong sponsors, grid positions, credible construction plans and bankable revenue strategies can access infrastructure-style lending pools. ### Sunprime €507 Million Solar and Storage Program In March 2026, [the European Investment Bank, Natixis CIB and Sunprime announced a financing program of up to €507 million ](https://www.eib.org/en/press/all/2026-096-italy-eib-natixis-cib-and-sunprime-sign-eur507-million-programme-to-deploy-one-of-italy-s-largest-solar-and-storage-portfolios?ref=blog.financely.io)for Project Sophocles in Italy. The program combines around 290 MWp of solar photovoltaic capacity with approximately 350 MW of battery energy storage systems. The EIB component can provide up to €271 million. The transaction demonstrates another major BESS financing trend: batteries increasingly sit within renewable generation portfolios rather than being financed only as standalone assets. Co-location can create operational and financing advantages where the assets share grid infrastructure and where storage can reshape the generation profile, reduce curtailment or increase the value of renewable output. ### CIM Group $600 Million California Hybrid Financing In June 2026, [CIM Group's Permanent Power Company closed an approximately $600 million financing facility ](https://www.cimgroup.com/press-releases/cim-groups-permanent-power-company-closes-approximately-600m-construction-financing-facility-for-grape-solar-and-energy-storage-project?ref=blog.financely.io)for its Grape solar and battery project in California. The project combines approximately 246 MWac of solar with 150 MW / 600 MWh of battery storage. The capital stack is particularly useful for sponsors to study. It included approximately $372.3 million of construction-to-term debt, a $166.7 million tax-credit transfer bridge loan and a $61.3 million letter of credit facility. That structure shows why describing a BESS financing simply as "project debt" misses much of the actual execution work. Construction liquidity, tax-credit timing and contingent obligations may each require separate facilities. ### Quinbrook Supernode Reaches Approximately A$1.2 Billion of Financing In July 2026, [Quinbrook announced financial close on A$469 million of additional debt for Stage 3 of Supernode ](https://www.quinbrook.com/news-insights/supernode-stage-2-completes-construction-and-commences-operations/?ref=blog.financely.io)in Queensland. The additional financing brought total project financing across the Supernode complex to approximately A$1.2 billion. Stages 1 and 2 total 520 MW / 1,858 MWh and operate under a long-term tolling arrangement with Origin Energy. Supernode illustrates the usefulness of contracted tolling revenue when scaling large battery platforms. It also shows how sponsors can finance projects in stages rather than attempting to capitalize an entire multi-stage development at once. ### Gresham House Finances 397 MW of UK BESS Pipeline In May 2026, [Gresham House Energy Storage Fund announced project finance for three UK battery projects ](https://www.lse.co.uk/rns/GRID/conclusion-of-new-project-financing-f3w218qo1wwgcjw.html?ref=blog.financely.io)totaling 397 MW / 794 MWh. Separate senior project-finance facilities were signed for Cockenzie, Monet's Garden and Elland 2\. The facilities cover up to 70% of individual project costs. The disclosure is useful because it provides a visible example of construction leverage in the BESS market. A 70% debt contribution does not mean every battery project can achieve the same leverage. Revenue contracting, sponsor quality, technology, construction risk and market exposure determine the actual debt capacity. ## What Recent BESS Financings Tell Us These transactions do not point toward one universal BESS financing model. They point toward a market becoming capable of financing several different risk allocations. ### Contracted Revenue Supports Leverage Capacity-market contracts, tolling agreements, PPAs and other contracted revenue structures can provide lenders with a more predictable base case. ### Merchant Exposure Has Not Disappeared Lenders can still consider merchant revenue, but debt sizing generally becomes more sensitive to downside assumptions and revenue volatility. ### Hybrid Projects Are Increasing Solar-plus-storage transactions can share grid infrastructure and create more diversified revenue and dispatch strategies. ### Portfolio Finance Is Developing Experienced sponsors increasingly finance several assets within one portfolio or platform rather than raising completely independent debt for every battery. ### Contingent Facilities Matter Guarantees and letters of credit can sit alongside funded construction and term debt, particularly where projects face contractual security requirements. ### Refinancing Is Becoming Part of the Market As batteries move from construction to operating assets, refinancing provides another route to reduce cost of capital and recycle sponsor equity. ## Tolling Agreements Are Reshaping BESS Project Finance One of the most important developments in battery finance is the increasing use of tolling structures. Under a tolling arrangement, the battery owner provides defined operating rights or capacity to a trading or energy counterparty in exchange for contracted payments. The exact risk allocation varies by contract. For lenders, the attraction is straightforward. A strong tolling counterparty can replace part of the uncertain merchant revenue stream with contracted cash flow. Modo Energy recorded only three standalone tolling agreements in Europe during 2024\. That increased to 15 during 2025, with additional project-finance deals incorporating tolling counterparties. Germany has emerged as an important tolling market. In June 2026, for example, [Next Kraftwerke and Eco Stor announced a five-year tolling agreement ](https://www.ess-news.com/2026/06/02/next-kraftwerke-and-eco-stor-sign-tolling-deal-for-300-mw-german-bess/?ref=blog.financely.io)covering 300 MW / 700 MWh of the Förderstedt project. Approximately 80% of the relevant capacity is tolled while 20% remains merchant. That mixed structure is important. Contracting 100% of revenues can reduce upside. Leaving 100% merchant can reduce debt capacity. Partial tolling can create a middle ground by supporting lender coverage while preserving some exposure to market upside. ## Merchant BESS Can Be Financeable, but Debt Sizing Is Harder Batteries create revenue differently from conventional contracted generation assets. A merchant battery may earn from several markets, including day-ahead arbitrage, intraday trading, balancing services, frequency response, capacity mechanisms and other grid services. That revenue stacking makes the asset commercially attractive but creates a more difficult project-finance model. The lender needs to decide how much of forecast revenue can reasonably be included in the debt case. Historical volatility, changing market rules, competing storage capacity and revenue cannibalization all affect that analysis. Merchant-heavy structures therefore tend to depend more heavily on lender downside scenarios, conservative revenue curves, debt-service reserves and sponsor support. ## Capacity Markets Can Create a Bankable Revenue Floor The R.Power Jedwabno financing demonstrates how long-duration capacity payments can support BESS debt. Capacity contracts do not necessarily cover the entire revenue requirement of a battery. They can, however, give lenders a predictable contracted component against which part of the debt service can be evaluated. The remaining merchant or optimized revenue can then provide additional cash flow and equity upside. This combination of contracted base revenue and market-based upside is likely to remain important in markets introducing capacity mechanisms or storage auctions. ## Co-Located Solar and BESS Project Finance Is Growing Standalone batteries still represent a large share of financings, but co-location is becoming more important. Q1 2026 European deal data showed standalone batteries falling to 66% of transactions from 88% during 2025 as more developers combined solar and storage. Co-location can improve grid utilization, allow renewable energy to be shifted into more valuable hours and provide additional flexibility around PPA delivery. Financing is not automatically simpler. The lender must understand how the solar and battery revenues interact, whether the assets share a grid connection, how charging restrictions work and whether one component can operate independently from the other. Sponsors developing hybrid portfolios can also review Financely's [solar and renewable energy project finance ](https://www.financely.io/project-finance-for-solar-and-renewable-energy?ref=blog.financely.io)capabilities. ## Australia Shows the Importance of Long-Term Offtake Australia's BESS market offers another useful financing model. In July 2026, [European Energy reached financial close on the Winton North solar and battery project ](https://europeanenergy.com/2026/07/02/european-energy-achieves-financial-closing-for-winton-north-project-in-australia/?ref=blog.financely.io)with financing from Commerzbank and Société Générale. The project combines 130 MW of solar with a 100 MW / 220 MWh battery and benefits from a PPA with Amazon. The transaction reinforces a recurring lender preference: where a credible corporate or utility counterparty supports the revenue profile, project debt can be structured around a more predictable cash-flow base. ## BESS Revenue Contracts Need to Be Underwritten, Not Merely Signed A signed tolling agreement or PPA is not automatically bankable. Lenders will examine the contract tenor, termination rights, performance obligations, availability requirements, credit quality of the counterparty, pricing mechanics, indexation, security arrangements and what happens if the battery underperforms. A ten-year contract with a weak counterparty can provide less credit support than a shorter agreement with a highly creditworthy buyer. Sponsors still negotiating their revenue arrangements should treat the [offtake agreement ](https://www.financely.io/offtake-agreement-explained-meaning-bankability-and-project-finance-use?ref=blog.financely.io)as part of the financing structure rather than a separate commercial document. ## The BESS Capital Stack Is Becoming More Sophisticated The Grape financing in California is a useful example of the direction of travel. Its approximately $600 million package combined construction-to-term debt, a tax-credit bridge and a dedicated letter of credit facility. A utility-scale BESS project may therefore require several distinct pieces of capital. | Facility | Purpose | Typical Repayment / Release | | ------------------------- | ---------------------------------------------------------------------- | --------------------------------------------------------------------- | | Construction Loan | Funds EPC, battery equipment, interconnection and other project costs. | Converts into term debt or refinances at completion. | | Term Loan | Long-term senior debt against operating BESS cash flow. | Amortizes from operating cash flow. | | Tax Credit Bridge | Bridges timing between project expenditure and tax-credit proceeds. | Repaid when tax-credit transfer or monetization proceeds arrive. | | Letter of Credit Facility | Supports grid, equipment, contractual or other contingent obligations. | Released or reduced when the underlying obligation expires. | | VAT Facility | Funds recoverable VAT associated with construction costs. | Repaid from VAT refunds. | | Mezzanine / Junior Debt | Fills part of the capital gap between senior debt and sponsor equity. | Subordinated repayment or refinancing. | | Sponsor Equity | Funds the portion of project costs outside debt capacity. | Returns generated through project distributions, refinancing or sale. | ## Letters of Credit and Guarantees Are Part of BESS Finance Battery developers can focus heavily on the funded construction facility and underestimate the contingent-credit requirement. Grid operators, utilities, equipment suppliers, landlords, EPC counterparties and other project parties may require letters of credit or guarantees. From the bank's perspective, those instruments consume credit capacity even when no cash has been drawn. That means the sponsor should model funded debt and contingent facilities together. A project with a $100 million construction loan and a $20 million letter of credit facility creates a different bank exposure from a project requiring only $100 million of funded debt. Where a project cannot independently satisfy those requirements, Financely also structures [credit enhancement ](https://www.financely.io/credit-enhancement-structuring---debt-support-for-financing?ref=blog.financely.io)for qualifying project-finance transactions. ## Tax Credit Bridge Financing Matters in the United States U.S. battery projects can have material timing mismatches between construction expenditures and realization of transferable tax-credit proceeds. A tax-credit bridge facility can finance that timing gap so that the project does not need to replace the entire delayed amount with sponsor equity. The lender still has to underwrite the expected tax-credit proceeds, eligibility, transfer process and timing. Financely separately arranges [tax credit bridge loan placement for battery projects ](https://www.financely.io/tax-credit-bridge-loan-placement-for-solar-battery-and-biogas-developers-waiting-on-transfer-proceeds?ref=blog.financely.io)where a qualifying developer has an identifiable tax-credit receivable or transfer process. ## How Much Debt Can a BESS Project Raise? There is no universal BESS debt-to-cost ratio. The Gresham House financings disclosed senior debt covering up to 70% of individual project costs, but sponsors should not treat that figure as a standard leverage assumption for every battery project. Debt capacity depends on the stability of project cash flows and the risks sitting ahead of those cash flows. Lenders will typically evaluate: - Contracted versus merchant revenue - Revenue contract tenor - Counterparty creditworthiness - Battery duration - Expected degradation - Availability assumptions - Cycle limitations - Augmentation requirements - Grid connection - EPC structure - Battery supplier - Warranty package - Operations and maintenance arrangements - Market saturation and revenue cannibalization - Construction contingency - Interest-rate assumptions - Debt-service coverage - Sponsor strength ## BESS Duration Changes the Financing Case A 50 MW / 50 MWh battery and a 50 MW / 200 MWh battery both have 50 MW of power capacity, but they do not represent the same economic asset. Duration affects the markets the battery can serve, capital expenditure, degradation profile and revenue opportunities. The recent market includes everything from relatively short-duration assets through four-hour batteries and emerging long-duration systems. Lenders therefore need the revenue model to correspond to the actual technical configuration rather than relying on a generic revenue assumption expressed only on a per-MW basis. ## Battery Degradation Is a Finance Issue Battery performance changes over time. Capacity degrades, cycling affects useful life and sponsors may need to augment the system to maintain contracted performance. Lenders will therefore pay attention to degradation curves, warranties, augmentation budgets and whether long-term revenue assumptions are consistent with the technical condition of the asset. An aggressive operating strategy that maximizes near-term merchant revenue can also increase cycling and potentially change long-term degradation. The financial model needs to connect dispatch assumptions to the actual technical life of the battery. ## Grid Connection Can Be More Valuable Than the Battery In many markets, obtaining a viable grid connection has become one of the most important development constraints. A battery with equipment procurement substantially advanced but an uncertain interconnection position may still be difficult to finance. Lenders will want clarity on connection agreements, required grid works, connection dates, curtailment, import and export capacity, and any security required by the grid operator. Co-located projects are increasingly attractive partly because they can make more efficient use of existing or shared connection infrastructure. ## BESS EPC and Supply Contracts Require Careful Allocation of Risk Battery construction looks simpler than building a conventional power plant, but large BESS projects still combine battery systems, inverters, transformers, substations, civil works, control systems and grid interconnection. Lenders will examine completion dates, liquidated damages, performance testing, warranty coverage, supplier credit quality and interface risk among contractors. The lender wants a credible route from construction drawdown to an operating asset capable of producing the base-case revenues in the financial model. ## Portfolio Financing Is Likely to Become More Important As experienced developers build pipelines measured in gigawatts rather than individual projects, financing every asset through a bespoke standalone process becomes inefficient. In January 2026, [terralayr raised portfolio-level senior project financing ](https://augustaco.com/transaction/augusta-co-advises-terralayr-on-senior-project-finance-raise-for-bess-portfolio/?ref=blog.financely.io)from ABN AMRO and Commerzbank for nine German BESS assets totaling approximately 112 MW / 238 MWh. The structure combined portfolio-level tolling with optimization of merchant revenues. Portfolio structures can diversify location, grid and revenue risk while reducing duplicated financing work. They also demand stronger sponsor reporting, standardized project documentation and portfolio-level controls. ## Operating BESS Assets Create a Refinancing Market The development of an operating BESS fleet creates another stage in the capital cycle. Construction debt can be refinanced once completion risk has disappeared and the lender has actual operating data. Sponsors may then seek longer tenors, lower margins or higher leverage based on established revenue performance. Refinancing can also release capital for new development. That creates the same asset-recycling dynamic already familiar in solar, wind and conventional infrastructure. ## What BESS Lenders Need Before Issuing a Term Sheet A large development pipeline is not enough. A lender needs a project that can move through diligence and documentation. - Site control - Grid connection status - Planning and permits - Battery supplier selection - EPC structure - Capex budget - Construction schedule - Technology and warranty package - Revenue model - Tolling, PPA, capacity or other contracts where applicable - Merchant revenue assumptions - Independent market study - Financial model - Degradation assumptions - Augmentation strategy - O&M arrangements - Insurance strategy - Sponsor equity plan - Required letters of credit and guarantees - Tax-credit assumptions where applicable - Downside sensitivities Sponsors preparing for lender outreach can use a [project finance bankability assessment ](https://www.financely.io/project-finance-bankability-assessment-platform?ref=blog.financely.io)before launching a full debt process. ## Debt Should Be Sized After the Revenue Case Is Built Sponsors sometimes begin with a target leverage ratio and then attempt to make the project fit it. BESS financing is better approached in the opposite direction. Build the technically credible revenue case. Stress market revenues. Incorporate degradation and augmentation. Define construction and operating costs. Establish contracted revenue. Then determine what level of senior debt the resulting cash flow can support under lender coverage requirements. If the project cannot support the desired leverage, the solution may involve more equity, junior capital, additional contracted revenue, credit enhancement or a revised project configuration. ## Recent BESS Financings at a Glance | Project | Market | Capacity | Financing | Structuring Point | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | ---------------------------------------- | --------------------------------------- | ------------------------------------------------------------------ | | [Greenvolt Ełk & Turośń ](https://www.enerdata.net/publications/daily-energy-news/greenvolt-secures-financing-400-mw16-gwh-bess-projects-poland.html?ref=blog.financely.io) | Poland | 400 MW / 1.6 GWh | €218m | Bridge debt plus €65m guarantee facility | | [R.Power Jedwabno ](https://www.erstegroup.com/en/news-media/press-releases/2026/06/05/erste-group-finances-landmark-battery-energy-storage-system-project-in-poland?ref=blog.financely.io) | Poland | 150 MW / 300 MWh | Approx. €64m | 17-year capacity contract plus optimization agreement | | [Thorpe Marsh ](https://www.sc.com/uk/?p=5219&ref=blog.financely.io) | United Kingdom | 1.4 GW / approx. 3.1 GWh | Approx. £595m debt | Large syndicated non-recourse project financing | | [Project Sophocles ](https://www.eib.org/en/press/all/2026-096-italy-eib-natixis-cib-and-sunprime-sign-eur507-million-programme-to-deploy-one-of-italy-s-largest-solar-and-storage-portfolios?ref=blog.financely.io) | Italy | 290 MWp solar + 350 MW BESS | Up to €507m | Portfolio-level solar-plus-storage finance | | [Grape ](https://www.cimgroup.com/press-releases/cim-groups-permanent-power-company-closes-approximately-600m-construction-financing-facility-for-grape-solar-and-energy-storage-project?ref=blog.financely.io) | California | 246.4 MWac solar + 150 MW / 600 MWh BESS | Approx. $600m | Construction loan, tax-credit bridge and letter of credit facility | | [Supernode ](https://www.quinbrook.com/news-insights/supernode-stage-2-completes-construction-and-commences-operations/?ref=blog.financely.io) | Australia | 520 MW / 1,858 MWh across Stages 1 and 2 | Approx.

Contracted batteries can increasingly access conventional infrastructure debt. Merchant projects may remain financeable but require more conservative leverage and stronger downside cases. Co-located assets are opening another market around firm renewable power. Portfolio financing is becoming relevant for experienced developers. Operating projects are creating a refinancing and asset-recycling market. At the same time, the capital stack is becoming more complicated. Construction debt may sit beside guarantee facilities, tax-credit bridges, VAT facilities, working-capital lines and project letters of credit. That makes BESS finance increasingly similar to mature project-finance sectors: lenders are no longer financing a battery simply because storage is strategically important. They are financing specific combinations of contracts, technology, counterparties, grid rights and cash flows. ## Frequently Asked Questions About BESS Project Finance ### Can battery energy storage projects be financed on a non-recourse basis? Yes. Large BESS transactions such as Thorpe Marsh demonstrate that non-recourse project finance is available for appropriately structured battery projects. Availability and leverage depend on the specific project, revenue structure, sponsor and lender underwriting. ### How much debt can a BESS project raise? There is no universal debt percentage. Revenue certainty, construction risk, battery technology, degradation, grid status, contracted cash flow and merchant exposure all influence debt capacity. ### Do lenders finance merchant BESS projects? Some lenders will consider merchant exposure, particularly for experienced sponsors and strong markets. Merchant-heavy projects generally require more conservative revenue assumptions and debt sizing than projects with contracted revenue. ### What is a BESS tolling agreement? A battery tolling agreement contracts some or all of the battery's operating capacity or economic output to a counterparty under agreed commercial terms. Tolling can provide a more predictable revenue component for project-finance underwriting. ### Can a BESS project combine contracted and merchant revenue? Yes. Hybrid structures can contract part of the battery while preserving a merchant component. The appropriate split depends on lender requirements, market opportunity and the sponsor's risk appetite. ### Can solar and battery storage be financed together? Yes. Recent transactions in Italy, California and Australia demonstrate project-finance structures combining solar generation with battery storage. Lenders still need to understand the economics and security of each component. ### Do BESS projects need letters of credit? Some do. Grid operators, utilities, suppliers, EPC counterparties and other project parties may require letters of credit or guarantees. These contingent facilities should be incorporated into the financing plan from the beginning. ### Can BESS projects get tax-credit bridge financing? In the United States, qualifying projects can potentially use bridge debt against expected transferable tax-credit proceeds, subject to lender underwriting of eligibility, amount and timing. ### What documents do BESS project finance lenders require? Typical diligence includes the financial model, revenue contracts, market study, grid documentation, permits, EPC and battery-supply agreements, warranties, O&M arrangements, insurance, technical reports, sponsor information and the proposed security package. ### What makes a BESS project bankable? Bankability comes from the combination of an executable construction plan, credible technology, enforceable grid rights, realistic operating assumptions, sufficient sponsor equity and a revenue profile capable of supporting debt under downside scenarios. ### Can Financely arrange BESS project financing? Financely works with battery storage developers and sponsors on debt structuring, lender placement, credit enhancement and the wider capital stack. Qualifying sponsors can review our [battery energy storage project finance ](https://www.financely.io/battery-energy-storage-project-finance?ref=blog.financely.io)capabilities. ## Raise Project Finance for a BESS Portfolio Financely works with battery developers and project sponsors seeking construction debt, term project finance, portfolio facilities, private credit, tax-credit bridges, guarantees, letters of credit and other structured capital.
