Indraprastha Power Generation Co. Ltd. (IPGCL) has tendered 30 MW of grid-connected rooftop solar PV projects to be installed atop government buildings in the state of Delhi under CAPEX and RESCO models. The bid-submission deadline is June 25, 2018.

IPGCL tendered the capacity on behalf of the Energy Efficiency & Renewable Energy Management Centre (EEREM Centre). The EEREM Centre is the nodal agency for rooftop solar projects in state of Delhi.

Of the tendered capacity, 3 MW will be developed under CAPEX mode and the remaining 27 MW under RESCO mode.

IPGCL has proposed three project categories under CAPEX model:

(A) 1 kW to 10 kW (500 kW)

(B) >10 kW to 100 kW (1,000 kW) and above

(C) 100 kW (1,500 kW)

The minimum bid capacity is 300 kW for category A and 600 kW for category B. Bidders for category C CAPEX mode projects must bid for the entire 1,500 kW capacity being tendered.

IPGCL has proposed four project categories under RESCO model:

(A) 10 kW to 25 kW (1,000 kW)

(B) >25 kW to 50 kW (2,000 kW)

(C) >50 kW to 100 kW (20,000 kW)

(D) above 100 kW (4,000 kW)

The minimum bid capacity is 600 kW for category A, 1,200 kW for category B, 8,000 kW for category C, and 2,400 kW for category D.

After selection of the lowest (L1) bidder under RESCO and CAPEX models, L2 and L3 bidders will soon be asked to match the L1 tariff.

A single bidder can bid for both CAPEX and RESCO, as well as  the different categories mentioned under each mode.

The scope of work includes site survey, design, engineering, manufacturing, supply, storage, civil work, installation, testing, and commissioning of the grid-connected rooftop solar PV project.

Terms for projects under CAPEX model require successful bidders to provide operation and maintenance (O&M) services  for a period of five years. For projects under RESCO model, successful bidders are to provide O&M services for a period of 25 years after the commissioning of project.

The project commissioning time frame is nine months from the date of issue of letter of award (LoA).

According to MNRE, Delhi has ~67 MW of cumulative rooftop installed capacity as of March 2018.

Delhi’s major distribution company (DISCOM), BSES Rajdhani Power Ltd (BRPL), recently launched an initiative called Solar City in the national capital. This initiative falls in line with the union government’s endeavor to expand the use of green energy.

Recently, the Delhi government released its draft Delhi Energy Conservation Building Code (ECBC) 2018. The draft ECBC aims to create minimum requirements for the energy-efficient design and construction of commercial buildings in the national capital.

In the draft code, the government stresses the importance of installing renewable energy generation, mainly rooftop solar, on commercial buildings across the city.
