invited to match the RL1 price subject to local supplier’s quoted price falling within
the margin of purchase preference and the contract shall be awarded to such local
supplier subject to matching the RL1 price.

In case such lowest eligible local supplier fails to match the RL1 price, the local
supplier with the next higher bid within the margin of purchase preference shall be
invited to match the RL1 price and so on and contract shall be awarded accordingly.
In case none of the local suppliers within the margin of purchase preference matches
the RL1 price, then the contract may be awarded to the RL1 bidder.

The provision for a Battery Energy Storage System (BESS) with the Solar PV
Project has been incorporated in the Scheme with the objective of improving the
quality of power injected into the grid by Solar PV plants that rely on an intermittent
energy resource like Solar radiation and thus, contribute to stable and secure
operation of transmission grid. Specifically, the proposed Energy Storage System is
intended to be used for PV Power Smoothing application. The utility of BESS for
ancillary services including features such as Active Power Regulation services
(primary control or Frequency response) etc., shall also be included which is only for
demonstrative purpose.

The BESS shall remain connected to the grid as per Central Electricity Authority
Technical (standards for connectivity to the grid) regulation 2007 with all latest
amendments and its components shall be designed accordingly. BMS shall ensure
safe operation and mitigate fire risk. The BESS shall be configured to perform
multiple charge discharge cycles.

86

Page 300 of 328

 2.5.1 PEAK SMOOTHING:-

The Prime application of BESS shall be smoothing of power output from the Solar
PV plant due to fluctuation in solar radiations. Peak smoothing shall be
demonstrated within the deployed battery capacity in MW, for above 75% of the
instances within the specified assessment window i.e., when a need for response is
detected. BESS should respond in a manner that the combined Solar PV and BESS
output at the Point of Common Coupling (PCC) targets the 15 minutes moving
average value of the Solar PV array output. BESS shall charge and discharge power
at appropriate ramp rate such that the smooth power output from the combined
BESS and Solar plant is injected into grid.

For the purpose of smoothing assessment, this BESS application shall be carried out
for during solar hours every day. The upper and lower SOC for BESS operation
shall be set as per the system requirements. The Battery manufacturer’s specification
and operating instructions shall be selected in such a way to suit the above
requirements. Temporal resolution of the data provided shall be minimum 1 second.

2.5.2 The PV smoothing Index Calculation shall be as follows:

Criteria
Description Criteria

M1 Measure/Count of Instances Count those records in the 10
when the BESS is expected to hour assessment period
respond for the smoothing (Minimum temporal
application resolution of one second),
where BESS is expected to
respond

M2 Count of those instances out of Count of the instances when

M1 when the BESS power output at PCC (Solar
successfully responded as PV output + BESS output)
required lies within +/- 2% of the 15
minutes moving average of
Solar PV Power Output
M3 M2/M1 M3=Ratio between M2 and
M1

M4 PV Smoothing index, PVS: M3 value of above 0.75 shall

The metric for Smoothing be acceptable.
Assessment At least 90% of the days in a
Contract year shall have
M3 above 0.75
The PV smoothing Index shall be dynamically calculated in the EMS and if it is less
than 0.75, then alarm shall be initiated. As per grid operator requirement or under
special emergency grid condition requirement the smoothing of solar PV plant

87

Page 301 of 328

 The BESS shall provide energy up to 30 min by providing immediate injection of a
large amount of energy for a short duration during the recovery period after any
sudden loss of generation within the power rating of BESS for example due to a
passing cloud cover.

2.5.3 FREQUENCY REGULATION:-

Frequency regulation provision shall be incorporated in BESS and the contractor

shall not consider any additional battery sizing for this application requirement. The
BESS shall be able to support grid during very low or high grid frequency by
supplying or absorbing power to/from grid. The power support shall be based on
power vs frequency droop characteristic for system frequency outside of the pre-
defined frequency dead band (say 49.5 to 50.5 Hz). The operation in this mode shall
be initiated by detection of low or high grid frequency while the BESS is in any
other mode. After normalization of grid frequency to normal operating range, the
BESS shall return to the mode in which it was operating at the start of frequency
regulation mode. Within the dead band frequency range the BESS do not have to
participate for frequency regulation operation. During detail engineering the actual
value of dead band frequency range shall be finalized based on CEA grid regulation.

2.5.4 ANTI-ISLANDING MODE:-

The BESS shall have anti-islanding protection as per IEC 62116 or equivalent
international standard

Outgoing feeders, grid parameters and using other required inputs, the EMS shall
ensure that none of the solar fluctuation and intermittency shall affect the grid
parameters. Based on the history of data of various grid parameters available in Port
Blair including existing 5 MWp Solar Power Project , the forecast shall be finalised
during detailed engineering to achieve the above functions in a coordinated way.

2.5.6 Components required to support reactive power shall also be taken into
consideration for design of EMS and BESS
