# Renewable energy transition > Renewable energy transition is jouleWise's electricity solution: contract and orchestrate green supply against your actual load profile. Canonical: https://joulewise.com/solutions/renewable-energy-transition Publisher: jouleWise Advisory Services Pvt Ltd, Noida, India · Spain Reviewed: 2026-10-08 Status: company page ## In short Intrastate and ISTS solar and wind, rooftop solar, storage and green-market purchase — contracted and dispatched together so the landed cost falls, not just the headline tariff. Most industrial renewable procurement is sized against an annual consumption number and a headline ex-bus tariff. Neither is what you pay. Open access charges, banking terms and the fifteen-minute matching of generation to load decide the landed cost — and a portfolio sized without them routinely generates units the plant cannot consume, which are paid for anyway. ## The problem Most industrial renewable procurement is sized against an annual consumption number and a headline ex-bus tariff. Neither is what you pay. Open access charges, banking terms and the fifteen-minute matching of generation to load decide the landed cost — and a portfolio sized without them routinely generates units the plant cannot consume, which are paid for anyway. ## What we do - **Plan against metered load.** Bills, load survey, rooftop and captive parameters. Solar, wind, hybrid, BESS and exchange electricity optimised together, capex or opex, with each state's ToD, banking and open access charges in the landed-cost model. - **Implement the contract.** Open access approvals, connection agreement, scheduling registration and ABT metering at the incomer. The regulatory work is the project; the panels are the easy part. - **Meter every source.** ABT metering and data loggers on every source and every load, so the position is measured block by block rather than reconciled annually. - **Orchestrate the mix.** ergOS schedules the portfolio against price and the production plan — including moving heat pump load into the cheapest, greenest blocks. ## Where it stops - **Matching, not capacity.** Renewable share is capped by what you consume in the block it arrives, not by what you contract. Beyond roughly 60% of a round-the-clock load, more capacity spills rather than substitutes; storage or a different solar–wind balance is what moves it further. - **State by state.** Open access economics are set by state regulation and change year to year. A case that works in one state can be marginal in the next, and banking rules in particular move. - **You choose who owns it.** Capacity can be yours (capex), funded by us and paid from measured savings (ESCO), or bought by the unit under a long-term electricity agreement (Electricity-as-a-Service). The structure changes the charges, so it is chosen with the business case, not before it. ## What we need to start - Twelve months of electricity bills - Contract demand and tariff category - A load profile at fifteen-minute resolution if available - Roof area and structural notes for behind-the-meter solar - Existing captive or open access contracts ## What drives the economics - Landed cost per kWh, not ex-bus tariff - Open access charges: wheeling, banking, cross-subsidy, additional surcharge - Capacity utilisation factor by resource and site - The share of generation you can actually consume - Grid emission factor, which decides whether electrification cuts carbon ## Facts - Plan against metered load: Bills, load survey, rooftop and captive parameters.

Generation only counts when it lands in a block you are consuming, which caps a round-the-clock industrial load near 60% before storage. Storage and a mixed solar–wind profile raise it further; the last few percent are usually the most expensive and are worth questioning. **What happens to the DISCOM connection?** It stays, as backup and as the route to the exchange. The aim is to make the grid a market rather than a supplier, not to disconnect from it. **Do we need capital?** No. We can fund it: under ESCO we invest and are paid from the measured savings, and under Electricity-as-a-Service you pay per unit below grid tariff. Capex is there if you would rather own the assets. ## Related - [See a campus switch in the RE Transition Studio](https://joulewise.com/studios/re-transition) - [How you buy it](https://joulewise.com/engagement) --- jouleWise · https://joulewise.com/ · sales@joulewise.com · +91 84483 22771
