Two challenger-firms – the consortium led by SunAsia Energy Inc. and SMC Global Light and Power Corporation (SGLP) – had been expected to put up tenders that should have challenged the 2,400MW solar and 4,000-megawatt hour (MWh) battery storage facilities submitted by Terra Solar. Nevertheless, on the actual auction date, the prospective bidders failed to submit their respective offers, hence, the PSA bidding was declared a failure. That then prompted the third party bids and awards committee (TPBAC) of Meralco to schedule another round of auction and the final submission of expression of interest will be on May 2 this year. Meralco has not given any pronouncement yet if 'negotiated deal' could be the next recourse if the second round of bidding would still fall through. The country's biggest power distribution company has not just been reinforcing its supply portfolio on this year's summer months – but also its medium and long-term electricity requirements.
