Who we are
Wert-Berater, Inc. has prepared independent feasibility studies for lenders, certified development companies, and federal agencies since 1998 — more than four thousand engagements representing $40.2 billion in evaluated project value across all fifty states and international assignments. Our fiduciary duty runs to the lender and the agency, never to the sponsor’s optimism: fees are fixed, quoted up front, never contingent on findings, and a determination is never changed under pressure.
What we do
Solar feasibility joins resource to revenue contract: the production estimate from irradiance data and system design — independently tested against P50 and P90 cases — the PPA, community-solar subscription, or merchant exposure behind the revenue line, interconnection position and upgrade cost allocation, and the incentive stack (investment tax credit, state programs, REAP grant where eligible) modeled at its real value and timing. Land control, setbacks, and decommissioning obligations are documented as the agency expects.
How we do it
Methodology uses NREL irradiance and production modeling, interconnection-queue and utility data, PPA and subscription review, and installed-cost benchmarks by system class. Coverage is tested at P90 production under the contracted case, with REAP documentation prepared to RD Instruction 5001 where the program applies.
How we can help you
Clean-energy engagements are prepared to USDA RD Instruction 5001 where REAP and B&I apply — including the energy-production documentation, incentive analysis, and payback arithmetic REAP requires — and to conventional and institutional standards otherwise, with interconnection and incentive risk addressed directly rather than assumed away. Representative clean-energy work includes a $52,688,000 green carbon project evaluation and renewable-energy feasibility within the firm's USDA REAP and B&I practice.
How to engage us
Standard delivery is 10 to 15 business days from complete project data. Rush delivery for deals already in underwriting is accepted case by case for an additional fixed fee, quoted up front and committed in writing. Engagements are typically initiated by the borrower, with lender or CDC confirmation obtained before work begins — institutions differ, so confirm the procedure with your lending contact.
