Open Access Solar

Buy solar power directly from our plants, at a price significantly below your current grid tariff

Open access solar gives commercial and industrial consumers the right to source power directly from an independent generator with zero capex and paying only for what you use, at a fixed price you negotiate upfront.

What is open access solar?

In India's electricity framework (Electricity Act 2003 and amendments thereof), open access is the right of large power consumers to purchase electricity from a generator of their choice rather than being captive to their local DISCOM. You continue to use the same grid infrastructure, but the power you consume is sourced from a solar plant you have a direct agreement with, at a tariff you've negotiated.

For commercial and industrial consumers, this means:

  • A fixed, predictable electricity tariff for the duration of your PPA
  • Significant savings compared to escalating DISCOM tariffs
  • A credible path to your ESG commitments
  • Zero capital investment, no panels to buy, no infrastructure to own

What does it actually save you?

The savings depend on your current tariff slab, connected load, state of operation, and the structure of your open access agreement. For most C&I consumers in Tamil Nadu and Andhra Pradesh, the saving typically ranges from 25% to 40% on your per-unit electricity cost. The key cost components in open access power are:

Generation tariff

The price you pay Good Energies for the power we generate.

Wheeling charges

Paid to the DISCOM for use of their distribution network.

Banking charges

For storing surplus units in the grid for later use.

Cross Subsidy Surcharge (CSS) and Additional Surcharge (AS)

A regulatory charge; varies by state and consumer category.

Scheduling and system operation charges

For coordinating power flow through the SLDC.

Even after all these charges, open access solar consistently delivers a lower landed cost than grid power for most industrial consumers, and that gap widens every year as DISCOM tariffs continue to rise.

Why open access makes financial sense now

DISCOM tariffs in Tamil Nadu and Andhra Pradesh have risen consistently over the past decade and show no sign of stabilizing. A fixed-price open access PPA effectively locks in your electricity cost for the tenure of the agreement, turning a variable, unpredictable operating expense into a known, budgetable line item that directly improves your operational margins and makes your business more competitive.

Consider what a 30% saving on electricity costs means for a facility consuming 5 lakh units per month at ₹8 per unit:

₹40 lakhs
Current monthly electricity bill
₹12 lakhs / month
Potential saving at 30%
₹1.44 crores
Annual saving
₹14+ crores
Over a 10-year PPA tenure

These are indicative numbers. Your actual saving will depend on your specific consumption profile and applicable charges. We will run the exact numbers for your facility before you commit to anything.

Is your facility eligible?

Open access is available to consumers who meet the minimum contracted demand threshold set by the relevant State Electricity Regulatory Commission. Eligibility criteria vary slightly between states. In general, open access solar is most commercially viable for facilities with:

  • High and consistent daytime power consumption
  • Current grid tariff above ₹5 per unit

If you are unsure whether your facility qualifies, get in touch and we will advise on applicability for your situation.

How it works — from enquiry to power supply

1

Share your requirements

Tell us your facility location, connected load, and approximate monthly consumption. We require last 3 months of your electricity bills.

2

We run your savings analysis

Our team assesses your consumption profile, applicable charges in your state, and the most suitable open access structure for your facility. We provide you a non-binding PPA term sheet that would provide you estimated savings.

3

PPA structuring and signing

If the numbers work for you, we proceed to structure the Power Purchase Agreement, covering tariff, tenure, scheduling, and other commercial terms. Our team handles the regulatory paperwork.

4

Grid connectivity and scheduling setup

We coordinate with the SLDC and relevant DISCOMs to set up the open access arrangement, scheduling, and banking mechanisms as per prevailing State Energy Regulatory Commission's mandates.

5

Power supply begins

Solar power from our plants starts flowing to your facility. You receive regular generation and consumption reports, and your electricity bill reflects the saving from day one.
