Shri
Piyush Goyal Union Minister of State (IC) for
Power, Coal , New & Renewable Energy and Mines launched Weather Portal
for Power Sector in association with POSOCO and IMD at the meeting of the Forum
of Regulators here today .
Day
to day weather variations have an impact on load demand and energy production,
transport and distribution management, as well as energy prices. Extreme events
such as heat waves or cold waves, wind storms or floods can of course have
dramatic consequences on the production means or the electrical grid of a
country including physical damage to the infrastructure. The information
available in the Portal regarding weather forecast shall help State Discoms to
take pro-active steps regarding short term and medium term management processes
and supply planning requirements and also for better
planning for infrastructure availability to ensure cost effective and reliable
supply.

The Portal provides the following information :
·
Regional
Weather Summary : This provides Weather Outlook for the Region for the
current day and upto next 7 days. Weather stations of Meteorological department
have been mapped to the nearest important Electrical Station/ Power Stations in
each State.
o
Nowcast: It is used to
forecast weather for a short period ahead, updated every 3 hours
o
Weather
Forecast: It is provided for the current day and next 6 days
o
Weather
Warning: Special Nowcast warning is issued for the next 3 hours.
·
Radar: The Doppler
Weather Radar generates different displays and derived products of practical
utility based on standard algorithms. These displays are updated every 10
minutes.
·
Satellite
Images:
INSAT 3D is being used to monitor the Weather of Indian Origin. The image is
updated every 30 minutes.
·
Meteogram- The Meteogram
at Web-Portal provides plots for Meteorological variables such as Rainfall,
Cloud Cover, Temperature, Humidity, Wind, Speed, Sea Level Pressure, Indices
for Thunderstorm etc. for 10 days with a resolution time of three hours. Each
Meteogram provides information for the 10 km radius.
·
Region
Specific Forecast - Fog Forecast, Metar, Bay Bulletin, Coastal Area Bulletin,
Cyclone, Port Warning etc.
During
the meeting Shri Goyal launched another portal ‘MERIT’ (Merit Order
Despatch of Electricity for Rejuvenation of Income and Transparency). This has
been developed by Ministry of Power in association with POSOCO and Central
Electricity Authority. The MERIT Web portal displays extensive array of
information regarding the merit order of Electricity procured by State(s) such
as daily state-wise marginal variable costs of all generators, daily
source-wise power purchases of respective states/UTs with source-wise fixed and
variable costs, energy volumes and purchase prices. The web-portal also give
information regarding reasons for deviation from merit order such as must run
conditions, transmission constraints etc. The Web Portal can be accessed at
“http://vidyutmode.in/”

Information
available in the Portal shall help State Discoms to optimize their power
procurement in more efficient way leading to lower cost of power to consumers.
It will facilitate must run status for hydro and renewables and will promote
use of green and clean power more transparently. It will also promote
competition for lower costs as information will be available to all Stakeholders
including generators and utilities for more efficient procurement. Since the
information will be available to all consumers on continuous basis it will
create pressure on utilities for continued efficiency.
The
advantages of “Merit” Portal are as follows:
Ø Empowerment of the Consumer and
participative governance
Ø Transparent information
dissemination pertaining to marginal variable cost and source wise purchase of
electricity
Ø Promotes economy and efficiency
in operations
Ø Demystifies the utility portfolio
and its complexity
Ø Optimization of the power
procurement costs
Ø Facilitates renewable integration
and handling of the variability and uncertainty of renewables
Ø Indication of supply side
reliability, adequacy, and cost of power procurement
At
the meeting, Shri Goyal also released FOLD-POSOCO Report on Operational
Analysis for Optimization of Hydro Resources & facilitating Renewable
Integration in India .The report also elaborates on the
operational constraints being faced by the hydro stations.
The report concludes that there is scope
for additional peaking support of 3000-5000 MW with equivalent amount of
backing down in off-peak hours from the existing hydro power stations. The gain
from the optimized despatch on annual basis is estimated to be 5 paisa per
unit which is equivalent to earning of the order of Rs. 600 crore per year at
all India level.
