Optimal Power Solutions in partnership with Puerto Princesa to develop a sustainable city.

In June 2010 the City of Puerto Princesa in Palawan, Philippines formed a technical partnership with Optimal Power Solutions in order to address the city’s power shortage, currently estimated at 5 to 10 MW.

An ongoing and significant issue has been the provision of sustainable energy for Puerto Princesa. At present, diesel-powered gensets provide a capacity of 30 MW of power to the inhabitants of Puerto Princesa. OPS and the City Council plan to design and implement renewable energy sources to generate additional power supply, reduce diesel fuel consumption and promote a viable and sustainable energy future. It is envisaged that new renewable sources of up to 10 MW capacity will be integrated over successive phases. This renewable capacity will prioritise the export of photovoltaic power into the grid to better support and lower use of the current diesel generators. Phase One of 1 MW capacity shall be installed in 2011 progressing up to 2MW, 5MW and finally 10 MW providing for future load growth of the City.

The systems will combine solar photovoltaics, OPS proprietary inverter control technology, battery storage and diesel engines configured for 24-hour continuous power supply. OPS will provide the technical design, product technology, delivery, installation and service and maintenance of these new renewable services. The inverter technology will employ specially developed SCADA software for real time control management of the photovoltaic/diesel systems. This proprietary SCADA is currently in use in multi-megawatt grid-connect projects in India and has proven highly invaluable for real-time, remote monitoring of power generation and general system trends.

Puerto Princesa, Palawan: Background Context

Palawan is an island province of the Philippines located in the MIMAROPA region. Its capital is Puerto Princesa City and it is the largest province in the country in terms of total area of jurisdiction. Palawan is widely considered as one of the most important areas of biodiversity and conservation in the Philippines due to the outstanding environmental landmarks including spectacular limestone cliff formations, immense reefs teaming with marine life and significant mangroves. Puerto Princesa also contains an environmentally significant tidal underground river. Positioned in the Puerto Princesa Subterranean River National Park (PPSRNP), this unique natural phenomena was listed as a UNESCO Natural World Heritage Site in 1999. The PPSRNP is considered one of few examples in the Philippines whereby a concerted effort has been made to protect and manage the natural area.

The Puerto Princesa City Council is considered to be a leader of sustainable policies and is widely acknowledged as the cleanest and greenest amongst local Philippine governments. As a result, the PPSRPN and surrounding areas of Puerto Princesa are a source of national pride and a key element in the identity of the Philippine people. OPS looks forward to the ongoing technical involvement in regard to the development of sustainable energy and technology trends in the greater region of Puerto Princesa, Palawan.
