# ergOS Studio

> ergOS Studio shows what ergOS, jouleWise's operating layer, earns by scheduling movable industrial load against the fifteen-minute block price, and when it earns nothing.

## In short

The studio has two parts. The screen is a week of a bottling plant on ergOS at fifteen-minute resolution: demand, renewables, battery, exchange purchases and grid, with the time-of-day tariff zones and the price paid in each block. The calculator takes the schedulable electrical load, the share that can move in time, the flat price and the cheap-block price, the contract demand and the demand charge, and returns the energy saving, the demand saving, the effective electricity price and the total. Set the two prices equal and the energy saving goes to zero, which is a real situation the tool reports rather than hides.
## Facts

- Indian electricity markets and most industrial tariffs settle in fifteen-minute blocks, 96 a day; ergOS forecasts and dispatches on that clock.
- Default price points: ₹5.50/kWh running flat (landed green open access) and ₹4.00/kWh in the cheap blocks (solar blocks plus a thermal store); DISCOM tariff ₹8.50/kWh.
- Default scenario: 8 GWh/yr of schedulable load, 60% movable, 10 MW contract demand at ₹350/kVA/month, 8% peak shaved, giving about ₹1.06 Cr/yr, roughly 24% of the bill for that load.
- The screen's time-of-day zones are illustrative: off-peak 00–06 at ₹6.33, normal 06–18 at ₹8.44, peak 18–22 at ₹10.13, off-peak 22–24 at ₹6.33, with open access at ₹4.20 and a synthetic exchange price.

## Assumptions and limits

- The share of load that can move is a physical property of the plant — thermal storage volume and process slack — not something the software creates.
- Demand charges are billed monthly on contract demand; the demand saving is the shaved share of contract demand times the charge times twelve.
- The screen is an illustrative plant with illustrative prices dispatched by ergOS rules; a real screen runs on the site's meters and tariff order.

## Questions and answers

**What is ergOS?**  
jouleWise's operating layer: it meters electricity, steam, fuel and water every fifteen minutes, forecasts generation, load and price 96 blocks ahead, schedules with the state load despatch centre, trades the exchange markets, and dispatches heat pumps and storage against price.

**What does scheduling earn?**  
The spread between the flat price and the cheap blocks on the load that can move, plus the demand charge avoided by not starting everything together. On a flat tariff with no on-site generation the energy saving is zero and the case rests on metering, demand and disclosure.

**Does ergOS control the plant?**  
Only what is agreed per site. The default is metering, forecasting and scheduling with recommendations to plant operations; direct dispatch of heat pumps and storage is enabled per site with the plant team.

**Why is ergOS sold with esgOS?**  
Because the same fifteen-minute record that runs the plant is the evidence the disclosure needs. One record, two uses.
