One platform.
Four tiers of power.

Grid Studies includes multi-machine transient stability, CCT, OPF, and a real-time digital twin — capabilities that replace DIgSILENT PowerFactory (₹25–50L/year) for transmission and grid connection studies. At ₹4.56L/year annual, you are still paying less than 1/5th of the nearest equivalent tool. The Core plan covers all IEC/IEEE calculation modules that EPC and consulting engineers need day-to-day — the price tier reflects the value delivered to each segment, not artificial feature-locking.

Grid Studies. RE grid connection studies require transient stability analysis and CCT verification to satisfy grid code compliance (CEA, IEGC in India). The Grid Studies plan includes the multi-machine transient stability engine, CCT analysis, and AVR/PSS design modules. A single grid connection study charged to a client typically recovers the full year's subscription cost.

Professional. The Professional plan includes the OpenDSS unbalanced power flow engine and hosting capacity analysis — the tools distribution engineers use to determine how much rooftop solar or EV charging a feeder can absorb before voltage or thermal violations. No comparable tool exists at this price point for the Indian distribution sector.

No. The 14-day trial is completely free with no credit card required. You get full access to your plan's feature set. Payment details are only required when you subscribe.

Annual plans are billed once per year at a discount: Core saves ~14%, Professional saves ~19%, and Grid Studies saves ~12%. For Professional, annual billing works out to ₹12,999/month (₹1,55,988/year) instead of ₹15,999/month. You can switch from monthly to annual at any time — the unused monthly balance is credited proportionally.

Yes. Upgrades take effect immediately and you're charged only for the remaining days on your new plan. Downgrades take effect at the next billing date. This means you can start on Core for day-to-day EPC work and upgrade to Grid Studies when a specific project requires transient stability or OPF analysis.

Professional includes up to 3 seats, Grid Studies up to 5 seats. For larger teams — EPC firms, DISCOMs, STUs — the Enterprise site licence gives unlimited seats across the organisation from ₹15L/year. Contact sales@jdsancontrols.com for a quote.

Yes. We offer discounted site licences for IITs, NITs, universities, and research institutions — including access to the pandapower and OpenDSS engines for coursework and research. Contact support@jdsancontrols.com with your institutional email.

GridSense implements IEC 60909-0:2016, IEEE 1584-2018, IEC 60255, and other standards with full calculation traces citing clause references. Grid Studies tier includes a V&V test framework with IEEE-benchmarked accuracy statements. As with all engineering software, results must be reviewed and verified by a qualified engineer before use in any regulatory submission. GridSense is a calculation tool, not a substitute for engineering judgement.
