Resource Management Integral to Data Centre Operations Uninterrupted service is at the heart of successful data centre services. To provide uninterrupted, reliable services data centres require uninterrupted, reliable sources of power. Data centres consume significant amounts of energy, which account for circa 40 percent of their operating costs. Anders Andrae, Senior Expert - Life Cycle Assessment at Huawei, predicts that by 2025 data centres will account for 4.5 percent of the world’s energy consumption. Renewable Energy Integration Renewable energy can make a significant contribution to data centre operators’ energy needs. Google, one of the largest data centre operators, has achieved its goal of ensuring the company’s’ total purchase of energy from renewable sources exceeded the amount of electricity used. To achieve this Google buys renewable energy credits to offset its carbon footprint, the company does not actually build and use renewable resources for all of its data centres. Facebook, on the other hand, has fewer data centres and is primarily using renewable energy. Using renewable energy is one way in which major corporations can demonstrate sound corporate stewardship. High renewable energy targets, however, can be especially challenging for data centre operators in Indonesia and India, where coal remains the primary baseload feedstock. In developing Asian markets with unreliable power supplies, investing in their own renewable energy resources and onsite generation – including microgrids - offers data centre operators greater energy reliability and independence. Renewable energy sources alone, however, may not provide sufficient energy - or sufficiently consistent energy - to ensure a data centre’s uninterrupted and reliable operation. Cooling Requirements The largest energy requirement for a data centre is for cooling. To operate reliably, data centres require a stable temperature consistent with American Society of Heating, Refrigerating and Air Conditioning Engineers guidelines and/or original equipment manufacturer recommended operating temperatures. The high ambient temperatures and humidity in many Asian countries present a challenge to data centre operators, and may preclude the use of mechanical systems such as adiabatic cooling in favor of more traditional mechanical systems such as chilled water. A reliable supply of high quality water is vital for data centre cooling systems. A reliable water supply, of predictable quality, is also vital indirectly; because water is a vital component of most baseload power generation. The water consumed directly at U.S. data centres, and the water used to generate the electricity that powers them, is expected to reach 660 billion litres by 2020. Network Connectivity High-speed, low latency network connections and the low cost to move big data is as important as reliable power and available land for the data centre owner/operator. Connection to undersea fiber optic cable systems is critical in a global digital economy. In developed Asian markets, Singapore and parts of China for example, reliable power and water supplies – and good connectivity, are readily available. In developing Asian markets this is often not the case. Choosing the right partner for your specific needs is central to the long-term success of all data centre development projects. To simplify the decision-making process, here are six main factors to consider: At the nexus of optimum data centre performance is a reliable power source; a water supply of consistent quality and quantity; and fast, stable telecommunications connectivity. For investors, owners and operators to achieve speed to value, they should look for delivery partners with proven expertise in each of these individual disciplines and – perhaps most vitally – demonstrable expertise in their efficient integration. For leading-edge technology projects like data centres, Asia’s owners and operators, need to have confidence their delivery partners can combine world-class expertise, tailored to local needs, with regional delivery experience. Of the companies that meet this requirement, those specialising in critical infrastructure – power, water and telecommunications - will be the best schooled in safe, timely delivery and managing the risk of service interruptions. The surest way to a successful data centre solution is to select a partner who can identify and avoid common pitfalls, and maximize efficiency based on experience supporting the entire lifecycle of data centre assets. The most successful projects are those which can be built efficiently - without disruption to live sites for instance - and deliver optimal, predictable OPEX. With success dependent upon the integration of complex power, water and IT infrastructure there are significant benefits in choosing a technology agnostic advisor, rather than OEM, for data centre projects. This gives investors, owners and operators the freedom to access the technology, or technologies, best suited to their specific business needs. Providing the energy resilience data centres demand typically requires power from the grid to be supported by intermittent renewable energy sources, coupled with advanced energy storage and smart control; and sometimes power generated on-site using fossil fuels. As well as resilience such microgrid solutions can offer potential revenue streams as utilities often pay major users to reduce loads and peak times, and will buy surplus power generated or stored by a microgrid. Selecting the optimal site for a data centre is critical. Location choice is based on multiple criteria, including: Access to power, telecoms and water and potential symbiotic relationship between disparate industries, i.e. sharing common resources; importing recycled water; exporting heat. Tax incentives, regulatory requirements etc. Sufficient land for expansion Access to physical transport networks Access to sufficiently skill operational workforce Security: acceptable risk profile for natural hazards, criminal activity and political stability To learn more contact HarjiH@bv.com.
How are the Largest U.S. Cities Managing Rising Costs for Water and Sewer Services? According to respondents in the 2018-2019 50 Largest Cities Water & Wastewater Rate Survey, utilities are modifying how they charge for services to address revenue stability and affordability concerns.
With Grid Modernization, Utilities Poised For Most Visible Transformation The annual Strategic Directions Report series offers analysis and insights into key issues and trends facing the smart cities and utilities, electric, natural gas, and water utility sectors.
FLNG Solutions Prove To Be Much More Than Potential It was roughly a decade ago when the initial introduction of floating liquefied natural gas (FLNG) solutions sought to help bring uneconomic gas reserves offshore, such as those in remote locations, to the market. Over the past few years, however, we’ve watched as offshore FLNG capabilities have moved closer to the mainland, offering a very flexible and economical solution to operators looking to offload their supply around the world.
Four Big Trends in Gas-to-Power Hold Promise for U.S. Market Major energy shifts are afoot, and the United States will play a critical role going forward. The EIA projects that by 2022, the U.S. will become a net energy exporter, according to its newly released Annual Energy Outlook 2018. For natural gas, this shift will happen even earlier, around 2020, the EIA says.
Market Strives to Deliver Over Pipeline Challenges As if the persistent low-price environment wasn’t enough, rampant natural gas production in the Appalachian and Permian Basins is ramping up concern that pipeline take-away capacity can’t keep up. This comes as the United States natural gas industry prepares to enter one of its strongest growth periods to date, driven by increasing global demand for low cost natural gas supplies and growing domestic demand for cleaner energy sources.
Lifting the Burdens of Capital Improvement Programs For more than 20 years, Black & Veatch worked with the Winston-Salem/Forsyth County Utility Commission to upgrade its wastewater treatment system on a project-by-project basis. There were many short-term wins, but resilience dated master plan made the long-term a bit less clear. The real win, and biggest cost savings, required a different approach.
Customer Engagement Leads to Safer Natural Gas Operations for Community Baltimore Gas and Electric (BGE) is serious about their commitment to safe and reliable operations. To bolster their residential natural gas meter protection efforts, BGE partnered with Black & Veatch on an integrated plan to relocate and safeguard meters for more than 16,000 natural gas customers in the Baltimore, Maryland, region.
