[Reading previous post on R-APDRP, will help reader.]
The Integrated Power Development Scheme (IPDS) was formulated with below objectives:
- 24×7 power supplies for consumers in urban area,
- Reduction of AT&C losses as per trajectory (DISCOM-wise) finalised by the Ministry of Power in consultation with States and
- Providing access to all urban households. The above objective is to be fulfilled by identifying and addressing critical gaps in sub-transmission and distribution network considering all relevant parameters (such as voltage regulation, HT & LT ratio, optimum loading of transformers & lines, reactive power management, power factor improvement, standard of performance, ongoing works under other schemes) to arrive at broad scope of work to be implemented under the scheme.
Stakeholders of the IPDS Projects
- Power Finance Corporation Limited (PFC) shall be the Nodal Agency
- Distribution Reforms Committee (DRC) at the State level:
- Monitoring Committee
- Utility (DISCOM/Power Department):
- State Government
The scope of IPDS is as follows:
- Strengthening of sub-transmission and distribution networks including provisioning of solar panels.
- Metering of feeders/distribution transformers/consumers including prepaid/smart meters in Govt. establishment and AMI, Smart meters in SCADA towns (under R-APDRP).
- IT enablement and distribution strengthening work under R-APDRP
Like R-APDRP, Power Finance Corporation (PFC) is the nodal agency for execution of IPDS.
Some key worth noting points of IPDS are:
- Sub-transmission and distribution network of 66 KV, 33 KV, 22 KV, 11 KV, LT level is considered in this scheme.
- Work related to augmentation of existing sub-stations capacity by the installation of higher capacity/additional power transformer, HT lines for reorientation/re-alignment, new distribution transformers and augmentation of existing distribution transformers etc. is included in the scheme.Also, works related to renovation & modernization of sub-stations and lines are considered in this scheme. Under this, installation of numerical relays, augmentation of switching devices, placement of RMUs (Ring Main Units), Auto Recloser, Sectionlizer, FPIs (Fault Passage Indicators) etc. are considered.
- Works related to Underground cable is allowed in this scheme in densely populated areas and areas of tourism and religious importance.
- Works related IT Applications limiting to ERP, Customer Care Services etc is considered.
- Works related AMI, Smart meters in the towns where SCADA being established under R-APDRP is considered.
- AMR for feeders, Distribution transformer and high load consumers is considered in the towns where SCADA being established under R-APDRP.
- A Project Management Agency will be appointed by the utility for monitoring and ensuring timely implementation of the project. 100% grant will be provided by GoI towards expenditure incurred on Project Management Agency, which will be limited to 0.5% of the cost of works.
The funding mechanism under IPDS is as follows:
- GoI grant: 60% of project cost (85% for sp. cat states).
- 10% of GoI grant on approval of DPRs and signing of Bipartite/Tripartite agreement between DISCOM, State Govt & Nodal Agency on behalf of MoP.
- 20% of GoI Grant on the placement of Award by the utility.
- 60% of GoI grant on the utilisation of 90% of grant released by GOI (1st and 2nd Tranche) and 100% release of DISCOM contribution.
- 10% of GoI grant after completion of work.
- DISCOM contribution (own fund): 10% of project cost (5% for sp. cat states)
- Lender (FI/Banks) (loan): 30% of project cost (10% for sp. cat states)
A suitable Tripartite agreement will be executed between following parties to ensure implementation of the scheme in accordance with the guidelines prescribed under the scheme. A bipartite agreement will be executed in case of State Power departments.
- PFC as the Nodal Agency on behalf of Ministry of Power,
- the State Government and
- the DISCOM
AT&C loss is the acronym of “Aggregated Technical & Commercial losses” in the power distribution system.
The methodology for calculation of AT&C loss has been defined in the “Report on Performance of State Power Utilities” in consultation with CEA as below:
The AT&C losses represent the difference between energy available for sale (adjusted for transmission losses and trading in energy, Mkwh) and energy realised, (Mkwh). Energy realised is the energy billed (adjusted for trading in energy,
Energy realised is the energy billed (adjusted for trading in energy, Mkwh) factored by the collection efficiency. The collection efficiency is an index of efficiency in realization of Billings, current as also previous years and essentially focuses on the year-to-year movement of receivables. The same is defined in table below
|Net input energy (Mkwh)||Total input energy (adjusted for transmission losses and energy traded)||a|
|Net sale of energy (Mkwh)||Total energy sold (adjusted for energy traded)||b|
|Net revenue from the sale of energy (Rs. Crs.)||Revenue from sale of energy (adjusted for revenue from energy traded)||c|
|Collection efficiency (%)||(Net revenue from sale of energy-Change in Debtors for sale of power)*100/(Net revenue from sale of energy)||Ƞ|
|Energy realised (Mkwh)||Net sale of energy (Mkwh)*collection efficiency||c* Ƞ|
|AT&C Losses (%)||(Net input energy, Mkwh – Energy realized, Mkwh)*100/( Net input energy, Mkwh)||[a-(c* Ƞ)]*100/a|
- The utilities will identify need for critical gaps in sub-transmission and distribution network considering all relevant parameters such as consumer mix, consumption pattern, voltage regulation, AT&C loss level, HT & LT ratio, optimum loading of transformers & feeders / lines, reactive power management, power factor improvement, standard of performance etc. and on-going works under other schemes for efficient management of distribution system.
- Based on the assessment, utilities will prioritise scope of work to ensure
- 24×7 power supplies for consumers in urban area,
- reduction of AT&C losses as per trajectory (DISCOM-wise) finalised by the Ministry of Power in consultation with States
- providing access to all urban households.
- The utility shall prepare a Need Assessment Document (NAD) in prescribed format (being circulated by nodal agency separately) containing all relevant information along with justifications to substantiate the proposed scope of work and cost estimates. The NAD will be examined by the nodal agency to arrive at the broad scope of work to be covered under the scheme and the total cost in consultation with concerned utilities.
- Based on the broad scope of work validated by the Nodal Agency at Stage#1, the utilities will formulate bankable Detailed Project Reports (DPRs) based on detailed field survey and latest approved schedule of rates for various items of work.
- These DPRs, duly recommended by the Distribution Reforms Committee (DRC) at the State level, will be submitted by the utilities to the Nodal agency for appraisal.
- The Nodal Agency will separately provide comparable costs sourced from CPSUs for major equipment for reference of the utility.
- These reference rates shall be used as ceiling rates for sanctioning of the projects. The grant shall be extended on the sanctioned cost or award cost of the project, whichever is lower.
- While formulating DPRs, the utility shall necessarily consult the public representatives including Member of Parliament. The utility shall furnish a certificate to this effect while submitting DPRs to Nodal Agency.
