Pay your Tata Power-DDL bill on Subspace

Tata Power-DDL's CA number is 11 digits, longer than the 9-digit numbers BSES uses in south, east and central Delhi. It's printed near the top of the bill. Tata Power-DDL's own payment page shows the number in its virtual account format, TPDDLN0 followed by the 11-digit CA number, which is what you'd use for a bank transfer.

If you moved from a BSES area, check the length before paying through an app: an 11-digit number means Tata Power-DDL, 9 digits means BRPL or BYPL. See BSES bill payment for those.

Duplicate bill. Tata Power-DDL's billing FAQ says to register your CA number on its website, after which you can view bills and print duplicates any time. The Login → Customer link on tatapower-ddl.com takes you to Tata Power's customer portal, where you choose Power and the region Delhi. The same account works in the My Tata Power consumer app linked from the site.

Receipts and payment tools. Under Customers → Bill Payment you'll find:

• Download Last E-payment receipt: choose Energy Bill, enter the CA number and registered mobile number, and click Get e-Receipt.
• Last Payment Confirmation Slip: proof of the last payment recorded on your account.
• Pay Bill Online and Pay by entering Registered mobile No.
• Generate Online Prepaid Coupon: for prepaid meter users.

A receipt from a BBPS app is valid proof of payment too; keep its reference number until the payment appears on your Tata Power-DDL account.

Tata Power-DDL bills monthly at the same DERC tariff as the BSES companies. A typical domestic bill has these parts, in order: energy charge on telescopic slabs, a fixed charge per kW of sanctioned load (₹20/kW up to 2 kW, ₹50/kW for 2–5 kW, higher above that), the monthly FPPAS fuel adjustment, an 8% deficit surcharge and a 7% pension surcharge, and electricity tax. The Delhi government subsidy is then deducted if you qualify: the whole bill up to 200 units a month, and up to ₹800 for 201–400 units. Tata Power-DDL's Subsidy Eligibility Calculator under Bill Payment shows where you stand, and a Subsidy Opt-Out option is there for those who don't want it.

The FPPAS has been running high: DERC's August 2026 order put Tata Power-DDL's June 2026 figure at 18.50%, though discoms often levy a capped rate in a given month. Your bill shows the exact percentage applied. Late payment attracts a surcharge of 18% a year, charged per day.

Subspace connects to Tata Power-DDL through Bharat Connect, so the bill comes from the company and the payment is reported back to it.
