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.

Optimal Power Solutions has been contracted for the supply of power conditioning units and system integration for three sites in the Kinabatangan District of Sabah, Malaysia.

Each site compromises a solar hybrid power system that is designed for the supply of electricity to three villages of KG Batu Darat/ Laut, Kg Kuamut and KG Kuamut Seberang. The total combined solar capacity of 430kW across the three villages is expected to reduce fuel consumption by a minimum of 50 per cent. Optimal Power Solutions will provide three proprietary inverters of a combined 710kW capacity. The inverters include 2 x 250kVA Hybrid Power Conditioner, 2 x 30kVA Hybrid Power Conditioner and 4 x 100kVA Grid Export Conditioner, (further HPC & GEC information is available on our products webpage or downloads section).

The sites are very remote and can only be accessed at times via river barges. The Kinabatangan floodplain is located on the east coast of Sabah, Borneo, it is considered of enormous environmental importance for wildlife and the local community as it is arguably the last forested, alluvial floodplain in Asia. Due to the remote location and delivery routes, the cost of landed diesel is high, averaging RM$8 to RM$9 per litre in recent years. It is estimated that the systems discounted payback period for the larger villages will be less than 10 years with scope for a shorter payback period should fuel prices escalate further.

Solar hybrid systems are a particularly viable option for remote area power supply. Optimal Power Solutions is pleased to offer a complete range of proprietary inverters with full service system integration and project development inclusive of remote system monitoring software packages.

Pine Bluff is Trinity Grammar School’s outdoor education campus in NSW. It is situated on the Abercrombie River some 75kms from Crookwell. The outdoor campus consists of various freestanding buildings including a lodge, dormitory buildings, cottages, classrooms, a shed and a storeroom. In the summer groups of students attend the campus and participate in camping, bush walking and other similar activities.

Being in a remote environment a standalone power system is required.  Around 2001, the site had a remote hybrid system installed. That system included 12 kW of solar panels designed to supply power to the facility during the day. The system also utilized a 210kWh battery bank along with a 50kVA inverter system.

OPS carried out a site assessment and found that the battery bank had exceeded its useful lifetime. Also, a number of other maintenance tasks were needed to bring the system back to a satisfactory level of performance. OPS was employed to upgrade the existing system. This included a complete system upgrade of the original inverter to a new DSP controlled hybrid power conditioner including a SCADA remote monitoring package. The aging battery bank was completely replaced with 40 x 6V, 875 Ah batteries, and an MPPT solar regulator was integrated into the DSP control to ensure maximum yield of the solar energy.

The system upgrade was carried out in October and November 2009. It is now fully operational in its self-managed “automatic” mode and has been contributing significant amounts of solar energy to the peak summer load of the facility.  The system does this with the assistance of the 2 diesel generators on site and these are also controlled by the HPC unit.

OPS India has recently completed the prestigious solar power project at Governor house, Raj Bhavan, in Kolkata, West Bengal. Raj Bhavan Kolkata is the country’s first Governors residence to switch to solar power generation. India’s President Pratibha inaugurated the solar power system in December 2009.

West Bengal’s Governor Gopalkrishna Gandhi (grandson of Mahatma Gandhi), The Minister for New and Renewable Energy Dr. Farooq Abdullah, President Smt. Pratibha Patil and West Bengal Green Energy Development Corporation MD Gon Chaudhuri joined together to turn on the solar power at Raj Bhavan, Kolkata. Dr. Farooq Abdullah also announced the governments allocation of Rs. One Crore ($220,000 USD) for all Governor houses in the country to introduce solar power generation.

Mr Gopalkrishna Gandhi has been striving to build awareness of carbon emissions through green and energy efficient building initiatives. The introduction of solar power at Raj Bhavan is expected to reduce the buildings carbon emissions by 40%.  The first stage implementation of solar PV at Raj Bhavan is 10kW however by March 2010 a further 40kW will be added and connected to the grid. The final system will be about 110kW.

OPS India supplied the system design, products and power integration for the Raj Bhavan system.

“We will all pool our scientific, technical and managerial talents, with financial sources, to develop solar energy as a source of abundant energy to power our economy and to transform the lives of our people”

India’s largest pilot project of solar PV grid-connect is now online and a huge success!

OPS India (Optimal Power Synergy India) is in the final stages of its 3 megawatt grid connect project in Karnataka, India. OPS India has supplied the 3 megawatt project with all power conversion equipment and system integration. Whilst two thirds of the project is now fully operation and online, the final commissioning is set to occur in the next week.

This project will supply 3MW during daytime (11am to 5pm) to the state grid which will enable greater power capacity to meet the irrigation power supply demand. This pilot project is expected to facilitate future planned projects in the areas of Shikaripur taluk in Shimoga district and in Itnal village in Chikodi talu of Belgaum district. The Karnataka government is planning to launch a solar technology programme to over 3900 villages, estimated to meet the energy needs of 5.0 million people.

India will soon launch an ambitious plan to boost its solar power generation from 3 MW to 20,000 MW by 2022. The policy framework, known in official circles as “the National Solar Mission,” will address the high cost of manufacturing solar panels as well as the currently high price of solar power (in comparison to conventional coal power stations).

NEW DELHI: In a step forward, the Solar Mission under the National Action Plan on Climate Change got an in-principle nod from the PM Manmohan Singh, with a target of 20,000MW (20GW) solar power generated by 2020 being accepted.

The Solar Mission is one of the seven missions proposed under the National Action Plan on Climate Change which was unveiled last year, promising India’s efforts to tackle climate change at the domestic level. The Solar Mission provides a detailed road map demonstrative of India’s serious intent to become a global leader in Solar Power within the next two decades.

The plan covers both grid and off-grid solar energy generation and distribution. In the first stage, the draft envisages generating 1-1.5 GW of solar power by 2012, 6-7 GW by 2017 and 20 GW (installed) by 2020. It calls for using 40-50 million sq metres of surface area in domestic, industrial and commercial areas.

The government aims to achieve it by providing incentives to cut the cost of development and deployment of solar panels. The aim is bring down the cost of solar energy from Rs15 to Rs4-5/ kWh from Rs3.5kWh base 2009 and achieve parity with coal by 2030 (Rs2kWh). The plan is expected to help offer lighting to 3 million households by 2012.

Parliamentary members stated that “While keeping an ‘ambitious’ target the solar mission should be built within an ‘enabling framework’ emerging from international negotiations, It would be important to demand technological and financial support from the international community under the UN negotiations, for such a huge target for clean energies due to the uncertainty of the costs.”

The plan calls for setting up a statutory solar authority under the ministry of new & renewable energy. It will have three verticals _ finance, technology & tariff, special project. The body will particularly focus on installation of solar collectors in hospitals, hotels and government buildings.

‘‘The solar mission can be India’s response to the global climate change logjam. It will make India’s position stronger in the negotiations. If India can do so much unilaterally, imagine what India can achieve if financing and clean technology support from rich countries come through. It’s the right answer at the opportune time,’’ says Siddharth Pathak, climate & energy campaigner, Greenpeace India.

The solar energy industry in India has undoubtedly gained momentum and should be able to keep pace with the government’s aim of achieving 10% of the country’s total electricity requirements by 2012. India already possesses a balanced eco-system for the PV industry, a high-tech manufacturing base and skilled labour sufficient to make it a booming industry. Annual PV production has already reached over 300 MW, with about 85% being exported.

Key facts about India’s 20GW Solar Power plans

The $19 billion “National Solar Mission” plan spread over 30 years aims to scale up solar power generation from nothing at present to 20 GW by 2020. The plan has a “near term” target of 100 megawatts, and 100 GW by 2030, or 10-12 percent of total power generation capacity estimated for that year.

Once implemented, the project will ensure large-scale deployment of solar generated power for both grid connected as well as distributed and decentralized off-grid provision of commercial energy services.

India says it could cut about 42 million tonnes of carbon dioxide emissions with its new solar plan. An estimated 20 million solar lights are estimated to save 1 billion litres of kerosene per annum by 2020.
Solar-powered equipment and applications will be mandatory for hospitals, hotels and government buildings, and villages and small towns will be encouraged with micro financing.

The plan also outlines a system of paying households for any surplus power from solar panels fed back into the grid. The target would be to provide access to lighting for 3 million households by 2012.

3 megawatt solar PV system to be fully online by late 2009.

Optimal Power Synergy India Pty Ptd has signed an agreement to provide all power conversion and integration work for a 3 MW grid connect Solar PV project to be installed in Karnataka, India.

Karnataka has severe power supply issues due to a reliance on hydroelectric power generation coupled with lower monsoonal rainfall over the last few years. Hydroelectric generation capacity has diminished due to low dam levels. In response the Indian Government is interested in megawatt-sized PV systems at various locations in the countryside to improve power supply to villages and rural areas.

The 3MW Karnataka project is now under construction and the first megawatt will be online by late September 2009. The remaining PV power supply will be completed by November 2009.
