🌐 Connectivity for commercial and industrial consumers
🧩Why Connectivity is precious for C&I Consumers
Planning for renewables is half the story for commercial and industrial consumers . The other half is having a approval for connectivity including state transmission general network access. ( GNA as it is being called commonly) The reason why big developers like Renew , Azure , Avaada have exited (or not been successful ) in the commercial and industrial market , while small agile developers are , is because of connectivity approval. The mose agile developers are the ones who have connectivity ready.
For Commercial & Industrial (C&I) consumers aiming to secure reliable 24x7 renewable power ( not just only solar / wind ) at a competitive rate (₹5/unit- (₹6/unit-), connectivity to the transmission network is the first and most important puzzle piece. Here's why:
✅ The Challenge
-
C&I consumers increasingly demand 24x7 clean power, not just solar during the day.
-
Many need complex PPAs that combine solar, wind, and storage, often across states.
-
However, current models like LTA (Long-Term Open Access) , MTOA ( Medium-Term Open Access) , and STOA (Short-Term Open Access) limit flexibility and often don’t guarantee new transmission infrastructure.
-
DISCOMs are hesitant to sign long-term PPAs, leading to a rise in short-term, unpredictable power market behavior.
🔌 The Connectivity Solution
| Element | Long term or short term open acess (Old model )
|
General Network access (GNA) model
(New)
| | --- | --- | --- | | Access Type | Fixed point-to-point | Dynamic, pan-network access | | Flexibility | Low | High (contracts of varying duration) | | Infra Creation | Not guaranteed | Driven by actual usage & planning | | PPA Fit | Simple solar/wind | Complex 24x7 PPA support | | DISCOM Dependency | High | Lower, enables open access | | State RE Transactions | Mostly intra-state | Inter-state possible if aligned with CERC |
Here’s a simple 1-slide style explainer for:
⚡️ Does GNA Cover STU? ❌ No — and Here’s Why It Matters
✅ What GNA Includes:
-
Issued by CTUIL
-
Grants right to use the Inter-State Transmission System (ISTS)
-
Includes:
-
Injection validation (by CTUIL)
-
Intermediate ISTS corridors
-
Point of drawal (up to state periphery)
-
🚫 What GNA Does Not Cover:
-
State Transmission Utility (STU) Network
-
Intrastate lines (e.g., from Delhi periphery to DMRC station)
-
Local STU substation capacity
-
STU wheeling or scheduling
-
🧭 What You Still Need (If You're a Consumer Like DMRC):
-
STU Coordination
→ For physical drawal at your substation (must be cleared by SLDC/STU) -
Separate Charges
→ STU wheeling charges, losses, scheduling fees -
SLDC Confirmation
→ For real-time scheduling and availability
📌 Bottom Line:
GNA gives you a highway pass — but you still need a local road permit.
GNA ensures national grid access, but STU access is still your responsibility.
