01
Where you are.
A reading of your fleet, your finances and your exposure to climate and regulation, built from your own financial statements.
Trinomio · ESG–Energy Finance · EFI
Your track to the utility of the future, measured in cash.
EFI — Energy Finance Integration — joins the physics of your plants with the books of your company. It shows which assets earn their keep, how far you can grow without new debt, and what it is worth to adapt before the rules and the climate force you to.
The track
Every utility is somewhere on the road. EFI tells you where, and what the trip is worth.
02
Where you need to go.
The utility of the future: a company whose value comes from being available at the right place and time, not only from selling kilowatt-hours.
03
What the journey is worth.
The value of adapting, in colones: what your company is worth if it rebalances, compared with staying as it is.

Six questions EFI answers
The questions your board is already asking.
01
Which of our plants pay for themselves, and which drain cash?
Each plant gets two ledgers: the cash it earns and the debt it carries. Netting them shows contributors and drains.
02
How much can we grow without taking on new debt?
EFI projects ten years of cash left for investment after financing.
03
What do cheaper solar, batteries and electric vehicles do to what we already own?
They change both what a new plant costs and what your existing plants earn, hour by hour.
04
What happens in a dry year?
When your hydro produces least, the generation tariff you pay tends to rise. EFI tests both together.
05
What can storage earn now that grid services are being priced?
EFI values reserve and flexibility under the new rules, with tariffs still under review.
06
How do the new bills change our position?
EFI runs your company under today's law and under each bill before the Assembly.

From organic growth to capital markets
First we measure how far your own cash can take you. Then we connect you to capital for the rest.
01
Measure the gap.
Your organic growth rate, the rate you need, and the distance between them.
02
Make cash flows investable.
EFI separates each plant's cash flow, tests it under conservative production and dry years, and reports it on one standard method.
03
Connect to capital.
Investors buy cash flows they can understand, test and trust. A common method across utilities creates the uniformity that pooled financing needs. Trinomio works with regulated issuers and fund managers to reach them.

How it works
Sense. Size. Transform.
01
Sense
We read your last five years of financial statements and operating data, plant by plant.
02
Size
The engine simulates your fleet hour by hour, values each plant, and projects ten years of cash under climate, technology and regulatory scenarios.
03
Transform
We turn the results into a rebalancing plan and the financing to carry it out.

ESG–Energy Finance
Three forces move your value. Three obligations make them visible.
The forces
Technology change
Cheaper solar, batteries, electric vehicles and smarter demand.
Regulatory change
New laws and new prices for grid services.
Physical climate risk
Droughts and changing rainfall on a hydro-based fleet.
The obligations
IFRS S1 and S2
Sustainability disclosure, adopted in Costa Rica, with first reports due in 2028 on 2027 data.
Asset useful lives
The yearly review of how long each asset will keep earning, under IFRS accounting.
Access to finance
Banks must now assess climate risk in their loan books.
Ready for the new rules
One company, three possible rulebooks. EFI runs all three.
Ley 10086 (today's base case)
A single national price, regulated tariffs and, now, a pool for grid services.
Bill 23.414 (a national electricity market)
Retailers, aggregators and large consumers buying wholesale, which makes room for value by place and time.
Bill 25.781 (a strengthened central plan)
A stronger system operator inside ICE and larger limits for private plants.
The value of adaptation
Company value if it stays as it isCompany value if it rebalancesValue of adaptation
The yearly rebalance
Not a one-off study. A yearly cycle, like your annual audit.
- 01
Onboard. Your data, your fleet, your books.
- 02
Monitor. Climate, technology and regulation through the year.
- 03
Rebalance. What to keep, add, refinance or retire.
- 04
Report. To your board, your lenders and your disclosures.
Then the cycle starts again.
A yearly fee set by portfolio size and complexity, with a defined scope; interim reviews priced separately.
The ring
