RENEWABLES

Handles integrated solar and BESS, standalone storage and wind natively

Take a grid offer and a PPA to a lender ready appraisal for solar, storage, wind or integrated solar and BESS, with the credit view a lender would write.

Developers still spend weeks assembling a model a lender will accept, then call the usual names. O produces it in one pass and researches offtake backed and merchant capital beyond the names you already know.

Developers: turn a signed interconnection and PPA (or tolling agreement) into a full capital stack proposal and see the credit view a lender would write.
Landowners and land agents: use the land use screen to test solar, agrivoltaics, BESS or wind before committing to a full appraisal.
Funds and equity investors: see real documentation instead of high level teasers, with access to the data room once the developer invites you.
WHO USES O HERE
Renewables developer
Turn a grid offer and a PPA or tolling agreement into a full proposal with integrated appraisal and cashflow, and view what the funder’s internal credit paper would look like. Or simply produce an early one page teaser to assess equity appetite. O handles solar, BESS, wind, integrated solar plus BESS, EV charging and hydro (high level), then researches debt and equity counterparties.
Broker or adviser
Take a developer’s grid offer and PPA to a lender style proposal with integrated appraisal and cashflow, or a one page teaser to test equity appetite, without building the model yourself. Then press a button and conduct research across the 1,900+ funder database and beyond. A project takes minutes instead of days, so you can work more clients each month.
Landowner leasing for solar or storage
Check an option or lease offer against what the land could support. The land use screen scores solar, agrivoltaics, BESS and wind alongside every other use.
Installer or EPC
Give a commercial customer a rooftop solar appraisal with payback and finance options on the spot, instead of a spreadsheet that arrives next week.
EV charging hub operator
Appraise a charging hub with its grid cost, utilisation and solar self use, and see the credit view a funder would take.
Commercial building owner
Test rooftop solar or an EV charging hub on your own site and see the numbers a funder would want before you commit.
IPP, fund or equity investor
See the teaser, full proposal and cashflow in a consistent format once a developer invites you to the data room, so you can judge a project before you spend time on a call.
Energy consultant
Produce a lender style appraisal and teaser for a client project without building a model from scratch. O can effectively produce a bespoke model across the key renewable asset sectors.
INTEGRATED SOLAR AND BESS

Two assets on one grid connection are one scheme, not two projects added together

A solar farm and a battery that share a connection share an export limit, a connection cost and a risk profile, but they earn differently and wear out differently. A model that simply adds a solar spreadsheet to a battery spreadsheet gets the sharing wrong and the lives wrong. O models them as one scheme with two income streams.

Sharing one connection
Both assets export through the same wire, so the battery cannot earn what a standalone battery would. O applies a sharing adjustment to the battery income against a standalone book, plus the optimiser fee, and you can change both. In the other direction, the battery can absorb power the solar would otherwise lose when the export limit is reached, so curtailment on the solar side is modelled as low. That too is an input you can change.
Who pays for the connection
The connection is shared infrastructure with no cashflow of its own. O carries its cost on the more reliable contracted solar income, so it has a proper repayment schedule and is not left floating.
Solar degradation
Panels lose a little output every year. O applies an annual degradation rate to the solar yield, set inside the range lenders normally accept, and runs a sensitivity with degradation higher so you can see how much headroom the deal has.
Battery degradation
A battery wears differently. Its income fades in the early years, then settles, and the cells eventually need replacing or topping up. O models the fade, a cell replacement or augmentation event part way through life costed as a share of the original battery cost, and the end of the battery’s life, after which it earns and costs nothing.
Two lives, two debt tranches
The solar has a long life and can carry longer debt. The battery has a shorter life and carries shorter debt. O sizes the two tranches separately, steps the debt service down when the shorter tranche matures, and tests cover against the lender’s target. Because the battery income fades and ends, it is valued at a higher exit yield than the solar income.
US projects
The US version adds a behind the meter revenue mode and a planning grade tax credit and depreciation block. It does not structure tax equity and is no substitute for a tax adviser.

This appraisal was led by Claude and Grok, peer reviewed by ChatGPT and Gemini, with human input from people who understand this sector.

INDUSTRY DEFAULTS

Start from sensible numbers, then make them yours

To save you time, O pre populates industry defaults such as panel degradation, battery cell replacement timing and cost, optimiser fees, operating costs and insurance, contingency and professional fees, lender cover targets, arrangement fees, debt tenors and exit yields. Every one of those defaults is editable, and O flags the ones that look unusually light so you do not send a lender a number it will challenge.
