CEBU province said it is inviting challengers to a consortium’s unsolicited proposal for a 150-megawatt (MW) solar power plant.

In a statement, the province’s Economic Enterprise Council (EEC) said it received a proposal from the consortium, composed of Acciona Energia Global, S.L. and Freya Renewables, Inc., for a joint-venture solar power plant.

The EEC said the project proposal involves the “development, financing, operation, commissioning, owning, managing and maintaining” a 150-MW solar facility, whose output is deliverable to the National Grid Corp. of the Philippines or to any interested purchaser.

The project cost is estimated at P7.52 million, with a construction period of 32 months and a concession of 25 years, it said.

Citing provincial ordinances, the EEC said that a project of this type is required to undergo a Swiss challenge.

A Swiss challenge involves soliciting counterproposals from competing bidders, which the original proponent has the right to match.

Domestic corporations interested in filing a challenge are required to be duly registered with the Securities and Exchange Commission (SEC), while foreign corporations must be holders of an SEC License to Operate.

Challengers must also have “completed, developed, operated and maintained at least a 75-MW solar power plant” and have equity of at least P3.76 billion.

Bid documents may be obtained upon payment of a non-refundable fee of P10,000.

“Deadline set for submission of eligibility documents is 12 noon, Monday, Nov. 6, 2023. The eligibility documents shall be opened not earlier than 1 p.m. on the same date in the presence of the private sector participants’ representatives, if any, who choose to attend the scheduled opening,” the EEC said. — Sheldeen Joy Talavera
