    Brief description of the programme/project/initiative :

    “The Short Term Open Access (STOA) software solution has been developed for POSOCO WRLDC, Power System Operation Corporation Limited – Western Region Load Dispatch Center (WRLDC), Mumbai. This is a G2B application which allows providing online services for various utilities in the power sector. The STOA software allows to maintain GRID discipline and for smart load management. This is a n-tier application built on J2EE technology using JBOSS Application Server and MySql database server. The major functionalities of the software include • Online filing of applications by applicant • Forwarding/receiving concurrence to concerned State Load Dispatch Centers • Processing of applications for approval, prorata calculations based on availability • Generation of payment schedule • Scheduling for next day, surrendering of applications • Maintaining the curtailment details in case of transmission constraints • Monitoring of payments received and payment disbursements The application is hosted at WRLDC server and is on a cluster mode for fault tolerance, since the submission and processing of applications is a continuous process.”

    Why was the project started?

    The project was started with a aim to provide G2B services to the various applicants by providing facility for online application submission of requests for Short Term Open Access for Bilateral Transactions namely Contingency transaction, Day Ahead transaction, First Come First Serve (FCFS) transaction, Advanced Reservation. To implement the Central Electricity Regulatory Commission CERC guidelines for open access as a software solution and to process the applications effectively by WRLDC. The project would assist in streamline the processing of application. Applications received are more than the available corridor and thereby needs to approved on a prorate basis taking into consideration the no. of applications submitted and applications already processed. To provide a unique ID for the application and to monitor the status of the application processing by the applicant remotely. To do payment disbursement with effective storage of data and processing. Concurrences from various intervening regions, state load dispatch centres were also needed for processing the applications, the project allows the concerned intervening regions to view and give the concurrences immediately.


    The purpose of the project is to provide electronic means to computerize the POSOCO Western Regional Load Despatch Center (WRLDC), Mumbai activities and to enhance the use of technology as a cost-effective measure for Short Term Open Access functionality of POSOCO WRLDC. The project will provide web-based solution for Short Term Open Access, which is one of the offline activities, carried out by RLDC. The areas computerized are filling up Applications through browser, processing the applications, collection of STOA charges, online concurrence by various intervening regions, disbursement of payment, implementation of transactions, necessary interfaces for scheduling and generation of reports.

    Target Group: WRLDC users, Applicants – utilities All Regional Despatch Centres (RLDCs) National Load Despatch Centre (NLDC)

    Geographical reach: Across various powergrid utilities. (Length & breath of India Power Sector)

    Date from which the project became operational : Feb 2011

    Is the Project still operational : Yes

    10 points that make the programme/project innovative:

    “1. Provides eSolution for STOA, the workflow includes application submission to payment schedule generation & disbursement.

    2. Interfacing with Scheduling software

    3. Use of Power Exchange PX data for processing

    4. Centralized access at NLDC (National Load Despatch Centre)

    5. Assists in effective utilization of GRID

    6. Work flow for Short Term Open Access Functionalities

    7. Role based software access

    8. Based on Distributed architecture

    9. Developed using Open source technologies

    10. Architecture designed to have fault tolerant system.”

    List 5 achievements of the programme/project:

    “1.Move towards less paper usage

    2. Reduced the time for filling applications by the utilites

    3. Reduced fax and other offline modes of submitting applications

    4. Reduced time for processing open access request applications, effective storage, maintaining audit trails on editing the applications thereby maintain transparency

    5. Effective implementation of the CERC guidelines as when there are amendments in the CERC guidelines.”

    List 5 key challenges faced while implementing the programme/project/initiative and how they were overcome?

    “1. Implementation of changes as per the CERC guidelines The software was designed with providing the necessary configurations to be stored in the database, so that minimal changes in the coding is required to implement changes as per the CERC guidelines.

    2. Interfacing with existing PX and Scheduling softwares Developed tools to use the data from Power Exchange (PX) and to provide the required data for scheduling software in the required format.

    3. Providing centralized access at the National Load Despatch Centre (NLDC) Data transfer between WRLDC and NLDC was done by using scripts to create views with required data and then to upload the same to NLDC using Schedulers

    4. End user training Different levels of training was conducted namely System administrator training, User level training etc.

    5. Payment disbursement processing Necessary reports were generated to provide a effective payment disbursement by verifying the payment done by the applicants and then disbursement to other RLDCs and SLDCs.”

    List 5 points on how the programme can serve as a model that can be replicated or adapted by others?

    “1. Can be replicated in State Load Despatch Centres

    2. Use of J2EE,open source technologies allows for a cost effective implementation

    3. Uses Available transfer capability (ATC), transmission and other constraints effectively in processing the application.

    4. Role based software access model would provide a effective implementation solution.

    5. Developed based on Distributed architecture”

    List 5 points to elaborate on the scalability of the programme/project/initiative

    “1.The software is designed to cater to the no. of applications submitted at various state utilities also.

    2. The processing of approval for various types of applications are as per the CERC guidelines and would allow for reducing in the processing time if required in future.

    3. The software is browser independent , it behaves reasonably even in all browsers

    4. The Short Term Open Access software facilitates addition of functionality or modification of existing functions .

    5. Software is user friendly, adaptable and is with and uses role based access methods.”
