Objectives of the Proposed Project

► To make Sun Temple Town of Modhera, a model town drawing its energy requirements completely from Solar Power.

► Develop Modhera into an ‘Energy-Resilient’ and ‘Net Solar Energy Positive’ - potentially using Solar Energy based Technology

► To Demonstrate next-generation and relevant energy technologies to visitors.►Use of solar photovoltaic (PV)

►Utility-scale energy storage mainly Solar Energy

► Electrical Vehicle Charging Station based on Solar Energy

►Micro-grid and Smart Energy Center (i.e. smart metering, grid balancing, real-time demand-side management, etc.)

(1) Psolar + Pbess ≥ Lmodhera

(2) Isolar + Ibess + Igrid ≥ Imodhera where Igrid ≤ 0

(3) isolar + ibess + igrid ≥ imodhera where igrid ≤ 0

Project Technical Objective

Modhera Solarisation Project Objective – Technical Target

(4) isolar + ibess = imodhera where igrid = 0, vgrid = 0,

tilla) Grid is revived/restored ORb) Psolar + PBESS sustain the load, which ever is earlier

Psolar = Power generated by Solar Systems

Pbess = Power Discharged by Battery

Energy Storage System

Lmodhera = Non Agriculture (NA) plus

Agriculture (AG) Load of Modhera Village

Isolar = Current from Solar System,

Ibess = Current from BESS

Igrid = Current from 11KV Busbar ( If

supplied to P&T JGY feeder, then +VE)

where Vgrid = Voltage ( At 11 kV busbar)

For this project, Bidder have option to comply the condition

(A) Round the clock i.e within 24 Hrs

Psolar + Pbess ≥ Lmodhera Where Lmodhera = NA + AG

OR

(B) Day Time & Night time

Psolar + Pbess ≥ Lmodhera Where Lmodhera = NA + AG ( Day time)

Psolar + Pbess ≥ Lmodhera Where Lmodhera = NA ( Night Time)

Sl. No. Component Requirement

7 Smart Energy Components

(a) Advanced metering

infrastructure (AMI) and

distribution automation

Establishment of Smartmeter on every connection ( aprox. 1700 Nos. ) with strong and efficient data communication system

Establishment of Smart Energy Center (SEC) to monitor all components of entire projects at single location as well as to display important parameters to Public at a large in vernacular language ( Hindi, Gujarati & English)

(B) Solar Based EV Charging

Station

Establishment of State-of the Art Charging Station with Solar Panels

(C) Modhera Grid Up-

gradation and

Modernization

Establishment of Remote controlled Switching unit , with provision of VAR Controller, within 66/11 kV S/S under compliance of Indian Electricity Codes, in consolation with GETCO

Note :(1) The building of Solar Charging Station and Smart Energy Center may be one only. SEC may/may not do controlling activity but

it must accumulate all information from all components of the project .(2) There must be one large display screen( Not less then 8” x 6” ) for public at a large for information(3) The data communication amongst all equipments is very important. Successful EPC Contractor must develop strong data

communication system with necessary back up.(4) All visible structure / building must have good Architectural design, good ergonomic view complying to all relevant standard.
