tw1nx energy world: optimization library and digital twin of the site
Today

You contact five companies one by one, wait two weeks and get five calculations with different numbers.

With tw1nX

One analysis. Every offer builds on it. Done in 30 minutes.

How it works

For your own project or your customers’. Four steps, one result.

  1. 01

    Create a project

    Upload site and load profile. tw1nX adds grid fees, levies and market prices automatically.

  2. 02

    Build the digital twin

    Model existing PV, consumption and grid connection. Then pick what to evaluate: storage, PV, wind.

  3. 03

    Let it compute

    tw1nX finds the most economical combination and size. With numbers you can trace.

  4. 04

    Hand over the offer

    The indicative EPC offer is already attached. You set your own commission. Your customer gets analysis and offer as one package.

One project, every offer. On the same numbers.

tw1nX first computes the optimal sizing. Then it puts what an EPC actually offers right next to it. You see both variants in direct comparison: net present value, savings, payback, return.

EPCs, marketers, power suppliers and O&M providers list their services once. Their offers are built straight from your analysis. Same load profile, same dispatch, same numbers for everyone.

  • EPCConstruction offer with optimal sizing, indicative right away
  • MarketerRoute-to-market offer matching load profile and dispatch
  • Power supplierSupply contract when the new dispatch needs one
  • O&MMaintenance and operations as an offer in the package
  • FinancingFinanciers and leasing calculate on the same numbers
  • Your commissionAs a consultant or sales partner you set it directly

Who is tw1nX for?

I want to size a project, for myself or my customers
OperatorsCommerce and industry. You get analysis and all offers as one package, instead of five requests and five waits.
Energy consultantsYou compute clients reliably in minutes. Report, client link and offer come straight from the analysis, your commission included.
Project developersYou screen sites quickly and compare scenarios before putting money into planning.
I offer services
EPCsYou list services once and receive requests from fully computed projects. Optimal sizing included.
MarketersYou receive projects incl. load profile and dispatch. Your route-to-market offer docks right on.
Power suppliersDemand, load profile and procurement structure are ready. You offer the supply contract when it’s needed.
O&MMaintenance and operations as an offer in the package. Requests come from computed projects.
Storage manufacturersYou give your partner network a tool that finds and sells the right storage.
White labelShare analyses and reports under your own brand.

What tw1nX computes

All revenue streams in one calculation, not one by one. Under the hood, tw1nX solves a real optimization problem based on your 15-minute load profile. The result is the economic optimum, not an estimate.

  • Peak shavingThe storage absorbs expensive peaks. Your capacity charge drops.
  • Atypical grid useAvoid grid consumption in high-load windows and save up to 80 % in grid fees.
  • Self-consumptionUse more of your own solar power instead of feeding it in cheaply.
  • Spot pricesCharge when power is cheap. Discharge when it’s expensive.
  • Procurement optimizationShift purchasing into cheap hours, matching your tariff.
  • Wind and storageBoth on the same grid connection. Surplus wind goes into the battery instead of curtailment.
  • Green powerHow much self-sufficiency and green share is possible, and what it costs.

Frequently asked questions

How does the platform work?

You create a project: site and load profile. tw1nX builds the digital twin and computes the project completely. EPC, maintenance, marketing and, if needed, the power supplier dock onto this analysis. In the end you get the report and all offers as one package.

How are the offers created?

Providers list their services once on the platform. When a project is computed, the offers are built on exactly that analysis. Same numbers for everyone. As a consultant or sales partner you set your own commission directly.

What exactly does tw1nX optimize?

The most economical size and operating strategy for battery, PV and wind at a site. All revenue streams together: peak shaving, atypical grid use, spot prices, procurement optimization, self-consumption, green power.

What does real optimization mean, versus simulation?

Many tools simulate fixed rules and show a plausible result. tw1nX solves a mathematical optimization problem and finds the economic optimum. Not an estimate.

What data do I need?

Your load profile in 15-minute values (CSV or Excel) and the site. tw1nX adds grid fees, levies and high-load windows automatically. PV and wind can be existing or planned.

Can I model wind and battery on the same connection?

Yes. Wind and storage on the same grid connection, including the feed-in limit. Surplus wind power goes into the battery instead of curtailment.

Where is my data stored?

On servers in Germany at Hetzner, GDPR-compliant.
