Payment Ratification And Analysis in Power procurement for bringing Transparency in Invoicing of generators

Frequently Asked Questions

1. What is PRAAPTI portal all about?

PRAAPTI stands for Payment Ratification and Analysis in Power Procurement for bringing Transparency in Invoicing of Generators. It is a platform aimed at enhancing transparency and encouraging best practices in Power Purchase transactions. PRAAPTI receives periodic updates/information from onboard Generation Companies (GenCo) regarding their Power sale invoicing and payment receipts from various. This information is then analyzed at portal’s backend and the results are presented in form of industry standard parameters.

The portal is also available to download for free on Android and iOS platforms at following links.

  1. Android :

  2. iOS :

2. What information and analyses is available on the portal?

The information received from onboard Generators including monthly details about invoices raised to and payments received from DISCOMs is available on the portal. Presently information for only Long/Medium term PPAs is available is being sourced from these Generators.

Further, a host of analyses based on aforementioned information is available. This analysis has been segregated at two levels; National level and State level.

National Level Analyses:

  1. An assessment of relative monthly performance among states is presented in the form of a composite index (explained in later sections). This relative assessment highlights average deviation of a state’s DISCOMs from an ideal payment schedule for the particular selected month.

  2. An aggregate level Ageing Report of pending invoices highlighting outstanding situation of various DISCOMs is available.

  3. A chronological aggregate level performance analysis of all DISCOMs is made available with respect to their power purchase transactions.

State Level Analyses:

  1. A state level drill down of parameters presented at national level is available at this level in addition to following.

  2. Performance of state for the particular month in terms of relative comparison of Amount billed, Payment Received and Average Payable w.r.t. individual Generator.

  3. A DISCOM wise invoice pendency scatter chart to map pendency of each invoice in terms of its percentage pendency and days lapsed after corresponding due dates.

3. What is composite index and how has it been arrived at?

Data available for DISCOMs of a particular state is used to arrive at a ‘Composite Index’. Average score of the state on this Composite Index is then used to assess its relative performance against other states. Subsequently, the results are depicted on a scale showing Ease of making payments by DISCOMs of the state.

Estimation of Composite Index:

Composite Index is estimated for each state individually. A state might have multiple DISCOM-Generator pair instances each defined by a PPA (or a PPA/PSA arrangement involving a trader). Corresponding to each PPA, monthly detail of invoices raised and payments received by a Generator is captured. Complete bill cycle for each raised invoice is captured at every month’s end in arriving at receivable/payable position of the DISCOM-GENCO pair.

Details captured for individual invoices at month ends will include pendency status (in %) and no of days lapsed since due date. Based on above two parameters, a ‘Default Index’ is calculated for each invoice and ‘Average’ of all such Default Indices corresponding to a particular Generator is estimated at month end.

Subsequently, the aforementioned average of Generators having PPA with same DISCOM is relatively compared to arrive at a ‘Weightage schedule’ for individual Generator against other aforementioned generators. This weightage schedule denotes the ideal priority that the corresponding Generator should receive against other generators in the next month’s payout by the DISCOM in consideration. Further, total actual payout by the DISCOM in this ‘next’ month is used to arrive at a ‘Normative Payment’ schedule for individual Generators based on Weightage Schedule of each Generator.

Finally, percentage deviation Normative Payment Schedule fromActual Payment Schedulesis calculated for each DISCOM at the end of each month. Maximum of this deviation is then chosen as Composite Index. In case of states with multiple DISCOMs, again the maximum of this deviation is chosen as state’s composite Index.

4. Who stands to benefit?

Power sector resembles a typical value chain wherein generation of goods (electricity) and commercial realization occurs at two opposite ends and move in opposite directions. Inefficiencies in movement of either good or money along the value chain increases transactional costs for the entities involved and creates undue sinks of valuable resources. Most importantly, consumer ends up paying more for the same electricity as regulatory structures allow some of these costs to be passed on and finally be recovered from end consumer. This portal is aimed at enhancing commercial efficiency of Power Sector’s value chain through bringing transparency in aforementioned transactions.

Consequently, the benefits are shared by entire power sector. In particular Generators facing liquidity issues due to irregular payment of power purchase invoices by DISCOMs will be immediate beneficiaries.

5. What is in future scope of this portal?

The portal aggregates commercial information from Generation sector entities for various kind of analyses. Presently this information is only limited to invoice and payment details of billing cycle which will be expanded going forward based on suggestions and responses received. In terms of entities also the coverage will be expanded beyond onboard Generators to include state Generators and more IPPs. Additionally, the analyses is based on industry standard practices of receivable management and includes only those parameters which were found relevant in stakeholder discussions under present context. This section will also be augmented as and when suitable suggestions are received from portal users.

In fact, Ifthere are any improvement suggestions, feedback or queries regarding any feature of the portal, you may please email them to

6. How can a Generator participate?

If you represent a Power Generator company OR a Power Trading company in India, and would like to take benefit of this portal, then you may please email us your contact details on using your official email id alternatively you can click here to register.

Our operations team will immediately get in touch and facilitate your onboarding.

7. What is the difference between Overdues and Current Dues?

Overdue are those dues which are already past their due date (between 45- 60 Days) and remain partially or completely unpaid.
Current Due are those dues which remain partially or completely unpaid but are still not past their respective due dates (less than 60 Days).
