Today, PUB, Singapore’s National Water Agency announced plans to further explore floating solar PV systems at reservoirs. The agency is calling tenders for engineering and environmental  studies for a 50 megawatt peak (MWp) floating solar PV system in Tengeh Reservoir and a 6.7MWp floating solar PV system in Upper Peirce Reservoir (see <a href="http://public.prdweb.pub.gov.sg/sites/assets/PressReleaseDocuments/PR_PUB%20study%20on%20soalr%20panels_Annex%20A.pdf">Annex A</a>).</span></p><p style="text-align:justify;"><span lang="EN-US"></span>Solar PV technology has been identified as a key renewable energy source that has high potential for large-scale deployment in Singapore.  Solar energy reduces Singapore’s reliance on fossil fuels, <span lang="EN-US">contributes towards the national climate change mitigation pledges, and </span>supports PUB’s efforts to adopt renewable energy in our operations. Already, this form of clean energy is becoming increasingly cost-competitive and is being deployed extensively in Singapore and elsewhere in the world. While most solar PV panels are deployed on land or rooftops, waterbodies with significant surface areas present greater potential especially in land-scarce countries like Singapore. Overseas, China has a 40MWp floating solar PV system in Anhui province’s Huainan city, while United Kingdom has a 6.3MWp floating solar PV system in London.</p><p style="text-align:justify;">A floating solar PV system test-bed was launched at Tengeh Reservoir in October 2016. Results so far show that the system performed better than a typical rooftop solar PV system in Singapore, due to the cooler temperatures of the reservoir environment. To date, there were also no observable changes in water quality in the reservoir and no significant impact on wildlife from ongoing studies on water quality and biodiversity. Building on the results of the test-bed, PUB is exploring the feasibility of deploying a 50 MWp floating solar PV system at Tengeh Reservoir. The amount of energy generated can potentially power about 12,500 4-room HDB homes.</p><p style="text-align:justify;"><span lang="EN-US">With its close proximity to the Chestnut Avenue Waterworks, Upper Peirce Reservoir is another potential location that PUB is considering for floating solar PV.  Solar energy generated can be fed directly to the nearby Waterworks for its water treatment operations, helping it reduce its reliance on grid energy.</span></p><p style="text-align:justify;"><span lang="EN-US"></span><span lang="EN-US">PUB will be carrying out comprehensive environmental studies at the two reservoirs before making any decision on implementation. The studies also include developing environmentally sensitive designs and construction processes. For example, there will be no infringement into the forested areas. It is envisaged that the solar panels will occupy about 2 percent of Upper Peirce Reservoir’s water surface area and about one-third of Tengeh Reservoir’s</span> water surface area.</p><p style="text-align:justify;">To make a thorough assessment, the consultants to be appointed for the environmental studies will be assessing the significance of the impacts on all flora and fauna and water quality of the reservoirs. They will then recommend corresponding mitigation or avoidance measures and appropriate monitoring framework, which will be documented in an Environmental Management and Monitoring Plan (EMMP).</p><p style="text-align:justify;">PUB has also consulted environmental groups (see <a href="http://public.prdweb.pub.gov.sg/sites/assets/PressReleaseDocuments/PR_PUB%20study%20on%20soalr%20panels_Annex%20B.pdf">Annex B</a>) such as Nature Society of Singapore on the scope of the environmental studies, and will continue to consult relevant groups as the projects develop.</p><p style="text-align:justify;">Besides the testbed at Tengeh Reservoir, past solar projects by PUB include solar panels at land installations such as Choa Chu Kang Waterworks and Marina Barrage. PUB is also participating in HDB’s solar leasing contracts, under the government-led solar programme SolarNova, to install solar PV systems at Changi Water Reclamation Plant, Bedok Waterworks and WaterHub.</p><p style="text-align:justify;">“PUB will continue to study the feasibility of adopting clean energy in our installations. This will help us reduce our dependence on grid energy and carbon footprint. However, the lack of deployable land space imposes a limit on what we can reap from this clean energy. The natural option is our vast water surface but we want to study the possible impact and relevant mitigating measures very carefully before reaching a decision to proceed with large-scale floating solar PV deployment. We will continue to consult relevant groups as the studies progress,” said Tan Nguan Sen, Chief Sustainability Officer, PUB.</p><p style="text-align:justify;">PUB is a statutory board under the Ministry of the Environment and Water Resources. It is the national water agency, and manages Singapore’s water supply, water catchment and used water in an integrated way.</p><p style="text-align:justify;">PUB has ensured a diversified and sustainable supply of water for Singapore with the Four National Taps (local catchment water, imported water, NEWater, desalinated water).</p><p style="text-align:justify;">PUB calls on everyone to play a part in conserving water, in keeping our waterways clean, and in caring for Singapore’s precious water resources. If we all do our little bit, there will be enough water for all our needs – for commerce and industry, for living, for life.</p><p> Like us at <a href="http://www.facebook.com/PUBsg">www.facebook.com/PUBsg</a> <br>Follow us on <a href="http://www.instagram.com/PUBsingapore">www.instagram.com/PUBsingapore</a> and <a href="http://www.twitter.com/PUBsingapore">www.twitter.com/PUBsingapore</a> <br>Subscribe to our channel at <a href="http://www.youtube.com/sgPUB">www.youtube.com/sgPUB</a> <br>For our latest event photos, visit <a href="http://www.flickr.com/PUBsg">www.flickr.com/PUBsg</a> or <a href="http://www.pinterest.com/PUBsg">www.pinterest.com/PUBsg</a> <br>Download our mobile apps: MyWaters for <a href="https://itunes.apple.com/sg/app/mywaters/id533051315?mt=8">iOS</a>, <a href="https://play.google.com/store/apps/details?id=com.codigo.pub.mywaters&hl=en">Android</a> or <a href="http://www.windowsphone.com/en-sg/store/app/mywaters/1089ffe2-749f-4487-9193-675d356036ee">Windows Phone</a> <br>Visit our website at <a href="http://www.pub.gov.sg/">www.pub.gov.sg</a> </p>29/9/2017 2:29:55 AM
