Energy optimisation · All India
More value from every kilowatt.
ekion helps Indian factories, warehouses, cold storage, housing societies and EV fleets cut their electricity bills. We simulate every solar, battery and EV-charging option hour by hour to size the right setup, then run it with AI-based energy management that keeps your loads in cheaper hours and your peak low.

Hardware-agnostic. We work with the equipment you choose.
In India, when you use power now matters as much as how much.
Business electricity in India is moving to time-of-day billing. Peak-hour power for commercial and industrial users must cost at least 1.2 times the normal rate, and solar-hour power at least 20% less. Your demand charge is also set by your single highest spike each month. The same load, run at the wrong time, costs more.

What timing changes
Size it right. Then run it smarter.
ekion works in two steps. First, TakaSim simulates your site for a full year, hour by hour, and finds the solar, battery and charger sizes that pay back best. Then TakaOS, through an Edge box on your site, runs that setup every day so flexible loads use cheaper hours and your peak stays low.
01 Design · TakaSim
Build the right energy setup.
TakaSim models your load, tariff and site for a full year, hour by hour, and tests hundreds of solar, battery and charger sizes. You get the size where adding more stops paying back. Results in 1 business day.
02 Optimise · TakaOS
Make every kilowatt work harder.
The Edge box on site connects your meters, battery and chargers to TakaOS, which uses AI to shift flexible loads into cheaper hours and hold your peak down, every day.

Five services. Start with the one that matches your problem.
ekion offers five services for Indian businesses: energy audit and sizing, energy management with TakaOS, solar and battery sizing, EV fleet charging, and energy economics. Each one starts from your real data and a TakaSim simulation, and each has its own page with the scope, the deliverables and what we need from you.
Energy audit & sizing
Know what to install, and how big, before you spend.

From your bill to a lower bill.
Working with ekion takes five steps. You share your location, electricity contract and load curve. TakaSim simulates every option for a full year and returns results in 1 business day. You choose the setup and the hardware brands. We connect the Edge box, and TakaOS optimises your site every day.

05
Optimise every day
TakaOS keeps loads in cheaper hours and peaks low; you see the saving against an agreed baseline.
Built for sites with big bills and real constraints.
ekion works with sites where electricity is a large, hard-to-control cost: factories and commercial buildings, logistics depots and EV fleets, cold storage, hospitals and housing societies. Each has its own load shape, and the right setup depends on when that load happens, not only on how big it is.

How we keep our numbers honest.
ekion’s numbers come from TakaSim, simulation software from our technology partner Takaon. Every sizing report lists its assumptions, including tariff, equipment degradation, price rise and discount rate. Results from simulation are labelled “Simulated” and results from your meters are labelled “Measured”, so you always know which is which.

Common questions.
What does ekion do?
We help businesses in India cut their electricity bills. We size the right solar, battery and EV-charging setup with TakaSim, then run it with TakaOS, an AI-based energy management system, so loads stay in cheaper hours and peaks stay low.
What is TakaSim?
TakaSim is simulation software from our technology partner Takaon. It models your load, tariff and site hour by hour for a full year and compares hundreds of solar, battery and charger sizes before you buy anything, so you can see which size pays back best.
What are TakaOS and the Edge box?
TakaOS is AI-based energy management software. The Edge box is a small device on your site that sends data from your meters, battery and chargers to TakaOS and carries its commands back, so flexible loads move to cheaper hours and your peak stays low.
Which equipment brands do you work with?
Any. ekion’s approach is hardware-agnostic: TakaSim sizes the setup for your site, and TakaOS works with the meters, batteries and chargers you choose, whether you keep the brands you already use or pick new ones.
What do you need from me to start?
Your site location, your electricity contract and your load curve. With those, TakaSim sizing results come back in 1 business day. If you are not sure what to send, ask us and we will tell you exactly what we need.
Do you work outside my city?
Yes. ekion works with sites anywhere in India. Sizing runs on your location, electricity contract and load curve, so we can start remotely and send results in 1 business day. The Edge box goes on your site when you move to energy management with TakaOS.
