The Energy Efficiency Services Limited (EESL) has issued an amendment for its tender for 20 MW of grid-connected rooftop solar projects in Andhra Pradesh, revising the bid submission deadline to April 29, 2020.

It also amended a clause in the request for proposal (RfP) and changed the mode of implementation from the RESCO model to the CAPEX model. It added that the tender work would be on a turnkey basis with 25 years of operations and maintenance.

The RESCO model is a system where the developer owns the solar project, and the consumer only has to pay for the energy generated, whereas under the CAPEX model, the consumer has to bear all the capital expenditure involved in the project.

The tender was initially floated by the EESL in March 2020. The solar project capacities were divided into three packages.

Under package 1, the maximum capacity to be offered is 8 MW, 10 MW under package II, and 2 MW under package III. However, the capacity offered under each package may vary depending on the open roof area, states the tender document.

Interested bidders were asked to submit an earnest money deposit (EMD) according to the respective package. For package-1, the bidders need to submit a sum of ₹9.15 million (~$119,869), ₹10.4million (~$136,214) for package-II, and ₹1.94 million (~$25,409) for package III.

The scope of work included the design, engineering, supply, construction, erection, testing, commissioning, and operation and maintenance of the rooftop power projects on a turnkey basis.

Recently, Mercom reported that the EESL invited bids for power conversion systems and fast combo electric vehicle (EV) chargers. The scope of work includes the planning, supply, installation, and commissioning with three years of comprehensive on-site warranty for 1,020 power conversion Systems (PCS) of all types.

Previously, EESL invited bids from management agencies for the deployment of its electric cars to various government organizations and public sector undertakings (PSUs) on lease and rental models in Jharkhand.
