BSES net metering in Delhi — the process, and where it breaks
Delhi is four licensees, not one, and the file is rejected for the same four reasons every time. This is the document set, the order the DISCOM reads it in, the sanctioned-load trap that catches older colonies, and how the subsidy track runs beside it rather than inside your invoice.
Step zero — which licensee are you on?
Read it off the bill. The areas below are the broad pattern, and border colonies do not follow it.
BSES Rajdhani (BRPL)
South and west Delhi — Vasant Kunj, Saket, Dwarka, Janakpuri, Punjabi Bagh, Hauz Khas, Alaknanda.
BSES Yamuna (BYPL)
Central and east Delhi — Mayur Vihar, Laxmi Nagar, Karol Bagh, Daryaganj, Shahdara, Preet Vihar.
Tata Power Delhi (TPDDL)
North and north-west Delhi — Rohini, Pitampura, Model Town, Shalimar Bagh, Narela, Badli.
NDMC
The Lutyens' zone — Connaught Place and the NDMC council area, on its own separate process.
The six-stage Delhi net-metering process
- 1
Confirm the licensee and the sanctioned load on the bill
Same dayRead the DISCOM name and the sanctioned load off your own bill before anything else. Delhi has three private licensees plus NDMC, portals differ, and the plant capacity you can grid-tie is bounded by sanctioned load — not by roof area. Homes with a 3 kW sanctioned load and a 5 kW roof need a load enhancement filed alongside, or the inverter gets capped.
- 2
Register the application on your DISCOM's solar portal
1 working dayThe application is filed against the consumer of record on the connection — the name on the bill, not the resident. Mismatch between the applicant and the consumer name is the single most common first-pass rejection in Delhi, and it is unfixable by argument; the connection details have to be corrected first.
- 3
Single-line diagram and technical feasibility
Typically 10–20 working daysThe sub-division engineer reviews the SLD, the inverter certification, the DC/AC sizing and the earthing scheme. Feasibility is where a file sits when the paperwork is thin — an unclear inverter datasheet or an SLD that does not match the sanctioned load restarts the review rather than raising a query.
- 4
Installation strictly per the approved SLD
1–3 days on siteAnything installed differently from the approved diagram — a different inverter model, a different string configuration, an extra module — fails inspection. If the SKU changes between quotation and delivery, the drawing has to be revised before the crew goes up, not after.
- 5
Inspection and bi-directional meter
Typically 1–3 weeks after inspection clearanceThe DISCOM inspects earthing, isolators, MCB ratings and inverter certification, then installs the bi-directional meter. Import and export readings start from that date — that is your commissioning date for every downstream claim, including the subsidy.
- 6
Net-metering agreement, then the PM Surya Ghar claim
Next billing cycle onwardYou sign the net-metering agreement with the licensee. The central subsidy claim is filed on the National Portal after commissioning and is disbursed to your bank account — it is a separate track from the DISCOM file and it does not reduce your invoice.
The document set
The four reasons Delhi files get rejected
Applicant name ≠ consumer name on the bill
Inherited property, a bill still in a parent's name, or a tenanted flat. The DISCOM deals only with the consumer of record.
Plant capacity above sanctioned load
Common in older colonies where the sanctioned load was set decades ago. Enhancement runs as a parallel application and adds weeks.
SLD not matching the installed equipment
A last-minute module or inverter substitution after approval means the inspection fails and the drawing is re-filed.
Common-area roof with no society resolution
A flat owner cannot file against a shared roof alone. That route is virtual net metering, and it starts with a general-body resolution.
The fourth one is not a rejection to fix — it is a different route. Society and flat owners start here instead.
Subsidy and settlement — the honest picture
Central PM Surya Ghar support runs up to ₹78,000 and Delhi adds ₹10,000 per kW capped at ₹30,000, plus a generation-based incentive of ₹3 per unit for 5 years on smaller residential systems. All of it is credited to the consumer after commissioning — none of it reduces the invoice you sign.
On export: annual settlement — surplus units carried forward monthly, unadjusted balance settled at appc rate on fy close, settled on March 31 (financial year-end). Oversizing against your actual consumption converts surplus at a settlement rate rather than at your retail tariff, which is the quiet reason a bigger system is not automatically a better one.
