How It Works
We prove the savings before you buy the battery.
No guesswork, no pressure. STHYR's engagement starts with a zero-cost pre-feasibility study grounded in your actual consumption — so every number on the table is yours, not an industry average.
Data-Driven Sizing
Your load profile. Sized to your peaks.
A two-shift plant’s peak day in 15-minute intervals, with one 125 kW / 261 kWh STHYR cabinet. The battery clips the top 10% of intervals, discharges in the evening time-of-day peak, and recharges off-peak — keeping a reserve for outages. Toggle to compare.
Illustrative: synthetic load for a two-shift plant, not customer data. Assumes 90% usable capacity, 88% round-trip efficiency, 20% of capacity held in reserve for outages, and an 18:00–22:00 evening peak. The saving applies only if the cap holds on the month’s highest-demand day. Your feasibility study uses your own meter data — larger plants and deeper shaves need more cabinets.
The process
Seven steps from bills to battery.
Send us your electricity bills (12 months preferred) and DG consumption logs. We give you a pre-feasibility report about whether BESS is right for your facility — at no cost, no commitment.
We install an energy-monitoring device at your injection point for one month, and review 12 months of bills and DG logs to size the system to your actual load profile.
STHYR maps your consumption, outage profile and DG usage against your DISCOM tariff schedule. We size a solar + BESS system to your actual load — with degradation and round-trip efficiency baked in. No vendor rules of thumb.
You receive a comprehensive solar + BESS savings report: value-stack breakdown by pillar, multiple financing options modelled for your balance sheet, technical product specs, and all supporting analysis in full detail.
STHYR does not ask for a right of first refusal. If we are not competitive to begin with, we do not deserve a second chance. You deal directly with the people who build the model. The report is yours to keep regardless.
Detailed engineering, procurement and commissioning of the solar-coupled BESS. Built to standard, with bankable documentation for lease or PPA financing if that is your chosen route.
Remote monitoring and O&M throughout system life. DG Fleet Review after 12 months of verified operation — to assess decommissioning and confirm the savings stack is delivering as modelled.

Is a BESS right for your facility?
Five indicators that point to a strong business case.
- Facility electricity cost above ₹10,00,000 per month.
- Fixed demand charges above ₹300/kVA/month, and/or frequent power cuts.
- ToD peak/off-peak spread of at least ₹3/kWh in your DISCOM tariff.
- Existing solar (possibly stranded) or rooftop space to add it.
- Ideally multiple facilities — so wins replicate across sites.
How we price & partner
Competitive pricing. No ROFR. No lock-in.
The feasibility fee is fully credited if you proceed. If you don't, you keep the report and we remove the devices. You deal directly with the people who build the model.
We won't ask for a right of first refusal for the effort of the study. If we're not competitive, you're free to walk — with your analysis in hand.
