About ISR Energy
Decades of cross-disciplinary experience.
The world energy transition is complex and rapidly evolving. ISR Energy helps our clients make optimally informed decisions to deploy practical, profitable energy transition projects.
With decades of experience in alternative energy development, energy as a service, real estate, and structured finance, our team understands the challenges you face navigating energy project deployment. We are technology and provider agnostic — which allows us to remain independently focused on our clients' best interests and be truly vested in your success.
We provide a full spectrum of development and advisory services focused on designing, funding, and delivering complex energy transition projects. From utility-scale solar and storage systems to microgrids and mission-critical facilities where energy resilience is paramount, we work with clients whose properties range from raw land to large real estate portfolios to facilitate energy transition projects that make financial and economic sense.
What we believe
Four commitments that shape every engagement.
- 01
Independent
We are technology and provider agnostic. Our recommendations follow your interests — not a manufacturer's quota or an installer's margin.
- 02
Open-book
Project economics, capital structure, and risk allocation are shared transparently. If it doesn't pencil, we tell you. If it does, we show you why.
- 03
Cross-disciplinary
Energy, real estate, and structured finance live in the same room. Most firms hand off between specialists. We sit in the room with you.
- 04
Long horizon
Energy projects close over years, not quarters. We design for the life of the asset — operating margin, refinancing optionality, end-of-life value.
Client services
Advisory, Development, and Funding — across the full energy project lifecycle.
Most engagements use more than one of the three. Some clients start with an Advisory engagement and grow into Development. Others come to us once a project is awarded and need Funding architected fast. We meet projects where they are.
Service
Advisory
Moving a compelling energy transition idea from concept to profitable reality is an extraordinary challenge requiring resources, knowledge, and experience typically outside our clients' core business.
Our comprehensive suite of services includes project feasibility assessment and due diligence, design and bankability, tax credits and incentives, local and national policy, energy offtake, and funding structures — to provide an independent view of how best to optimize the value of your assets.
Capabilities
-
Feasibility & due diligence
Site characterization, interconnection screening, environmental constraints, schedule realism.
-
Design & bankability
Independent engineering review against lender and investor expectations — before you're months in.
-
Tax credits & incentives
ITC / PTC positioning, transferability strategy, state and local incentive stacking.
-
Energy offtake
PPA structuring, hedge analysis, merchant tail modeling, corporate procurement frameworks.
-
Policy & regulation
ISO/RTO interconnection process navigation, NEPA where relevant, state policy briefing.
-
Capital structure
Independent perspective on the right capital stack for your project's risk profile and exit plan.
Who this is for
- Landowners considering utility-scale solar or storage on their property.
- Real estate portfolios evaluating distributed energy and resilience strategies.
- Corporate energy buyers structuring offtake or behind-the-meter generation.
- Developers seeking an independent second opinion on a deal in diligence.
Service
Development
We have found that an open-book, partnership approach greatly enhances the viability and success of energy projects.
As your project partner, we provide a full suite of development services for the design, development, delivery, and optimization of large-scale alternative and holistic energy projects. Our client partners range from landowners looking to develop greenfield utility-scale projects on raw land to holistic, resiliency-focused real estate and mission-critical building portfolios.
Capabilities
-
Utility-scale solar
Greenfield project development from site control through commercial operations.
-
Storage systems
Standalone and solar-paired battery storage — sized for revenue, sized for resilience.
-
Microgrids
Generation, storage, and controls for facilities that cannot tolerate outages.
-
Mission-critical facilities
Hospitals, data centers, defense facilities — energy systems where uptime is the product.
-
Real estate portfolios
Behind-the-meter generation, EV infrastructure, and energy-as-a-service for multi-asset owners.
-
Optimization
Operating-asset reviews, retrofits, repowering, and end-of-life value capture.
Who this is for
- Landowners with developable acreage and a long view on optionality.
- Real estate portfolios looking to convert energy spend into a managed asset.
- Mission-critical facility owners where resilience is a capital decision.
- Sponsors needing development capacity to close on an awarded site.
Service
Funding
Building an efficient capital stack is critical to the long-term project success and profitability of any energy project.
We bring extensive experience facilitating project funding — debt, tax, and sponsor equity — as well as pursuing federal, state, and local incentives and credits to financially optimize your project. Whether developing a project for sale or to retain, we have the relationships and experience required to maximize the value of your project near term and long term.
Capabilities
-
Debt structuring
Construction-to-perm, back-leverage, mini-perms, term debt — sized to project economics and sponsor balance sheet.
-
Tax equity
Traditional partnership flip structures and transferability-era capital — matched to project size and timing.
-
Sponsor equity
Strategic capital, infrastructure funds, and family-office capital across the project lifecycle.
-
Incentives
Federal ITC/PTC, IRA bonus adders (energy community, domestic content, low-income), state-level programs.
-
Capital stack optimization
The right mix of debt, tax, and sponsor equity for your exit plan and risk tolerance.
-
Sale or retention
Develop-to-sell or develop-to-hold — we build to the strategy, not against it.
Who this is for
- Sponsors moving from notice-to-proceed toward financial close.
- Owners evaluating refinance, recapitalization, or sale.
- Landowners considering equity participation rather than a flat lease.
- Operating asset owners exploring repowering or capital-return scenarios.
How We Work
A four-stage approach, built around your project.
Every engagement moves from idea to closed, operating asset along the same disciplined path. Where you enter and exit depends on what your project needs.
- 01
Discovery
We meet you where the opportunity is — landowner, real estate portfolio, corporate energy buyer, or developer. We listen, model the constraints, and identify whether the project pencils.
- 02
Feasibility & Design
Site diligence, interconnection studies, offtake structuring, tax credit positioning, and a clear-eyed view of bankability. No surprises later because we surfaced them now.
- 03
Capital Stack
Debt, tax, and sponsor equity sourced through our capital relationships — with federal, state, and local incentives layered in. Built to optimize for either retention or sale.
- 04
Delivery
Full-suite development support from notice-to-proceed through commercial operations. Technology and provider agnostic, always aligned with your interests.
