Why Capacity Limits Exist at All
Our NEPRA regulations guide mentioned capacity limits as one of NEPRA's key rules. This guide unpacks what that actually means in practice — because it's one of the most common reasons an otherwise well-planned solar system runs into an unexpected registration problem.
Capacity limits exist because the local grid infrastructure serving your property was designed around your sanctioned load, not an arbitrarily large export capacity. Registering solar capacity far beyond your sanctioned load could, in theory, overload local distribution equipment during high-export periods.

Sanctioned Load vs Solar Capacity
What Happens If You Want to Exceed Your Limit
| Situation | What You Can Do |
|---|---|
| Solar system sized larger than sanctioned load allows | Apply for a sanctioned load extension with your DISCO before or alongside your net metering application |
| Load extension approved | Net metering capacity limit increases proportionally to the new sanctioned load |
| Load extension denied or delayed | Size your solar system to your current sanctioned load, or explore installing in phases |
| Commercial connection with high future growth plans | Consider requesting a higher sanctioned load upfront to avoid repeat applications later |
How This Affects Your System Sizing Decision
Our system sizing guide calculates target kW based on your consumption. Before finalizing that number, cross-check it against your sanctioned load — if your ideal system size based on consumption exceeds what your current sanctioned load allows for net metering, you have two realistic paths: request a load extension, or size to the current limit and consider a future expansion phase.
Check your sanctioned load and its relationship to net metering capacity before finalizing your system size — not after ordering equipment. This single check prevents one of the more frustrating and expensive mistakes buyers make: purchasing a system that technically can't be fully net-metered under their current electrical connection.

Your sanctioned load is typically listed on your electricity bill or connection documents, and can also be confirmed directly with your DISCO if it's not clearly visible on your bill.
Yes, load extension requests are a standard DISCO process, though they involve their own application, review, and sometimes additional infrastructure charges depending on your area.
An oversized system relative to sanctioned load is typically flagged during DISCO review rather than causing outright rejection, but it will need to be resolved — either by load extension or system resizing — before approval.
Ratios can differ for commercial and industrial connections compared to residential, so it's worth confirming your specific DISCO's current policy for your connection type before sizing a larger system.
Technically the physical system could generate more, but only the portion within your approved net metering capacity would be eligible for export credit — anything beyond that wouldn't be officially registered or credited.
Timelines vary by DISCO and can run in parallel with or separate from your net metering application — confirm the current expected timeline directly with your DISCO before finalizing your project schedule.
