Power demand and supply at the Hotel Tierra Atacama<\/p>\n<\/div>\n

Busso von Bismarck, Head of Business Development, Founder & Management at Qinous Smart Energy Storage asks whether there\u2019s a two-step approach to clean energy for off-grid properties.<\/h3>\n

At the Tierra Atacama Hotel & Spa we recently held an event to launch an entirely emissions-free solar and battery storage system. The system had recently been upgraded.<\/p>\n

As both solar photovoltaic and battery storage technology continues to improve, the era of diesel electricity generation for hotels and resorts located beyond the reaches of established electricity networks, is ending.<\/p>\n

The reason for this is the triple payoff that a solar+storage system delivers, when compared to a diesel genset:<\/p>\n

    \n
  1. quiet and clean operation has a positive impact on hotel guest experience;<\/li>\n
  2. savings on diesel fuel provide a financial windfall and electricity costs can be locked in over the life of system \u2013 unlike fluctuating diesel prices;<\/li>\n
  3. the venue can achieve a dramatic reduction in CO2 emissions.<\/li>\n<\/ol>\n

    A fourth and little-known payoff is that solar+storage systems today can deliver a more reliable supply of electricity than diesel. This may seem counterintuitive, with the generation of electricity from renewable resources such as the sun and wind, often demonized as being \u2018highly variable\u2019 or \u2018unreliable\u2019.<\/p>\n

    While it is certainly true that the question regarding renewables begs, \u2018what happens when the sun doesn\u2019t shine or the wind doesn\u2019t blow?\u2019 However, the Tierra Atacama solar+storage system demonstrates that a well-designed and executed solar PV array plus an intelligent battery storage system can deliver a more stable, robust and reliable electricity to an off-grid facility.<\/p>\n

    The primary reason for this enhanced reliability is the better quality of electricity supply on a facility\u2019s \u2018micro grid\u2019 when supported by an advanced battery system. The battery can better meet the demands of a short-term peak in electricity demand \u2013 when energy hungry devices are switched on or off \u2013 by providing both the required voltage and the electricity frequency on the grid.<\/p>\n

    The regulation of electricity frequency on the grid is usually provided by what is known as \u2018spinning reserve\u2019, provided by fossil fuelled generators, which beyond the grid means a diesel genset. A battery can regulate this frequency instantaneously, rather than ramping up and down like a generator, providing a higher quality of power and protecting costly electric devices like computer servers.<\/p>\n

    Another benefit is that the Qinous battery unit, as provided to Tierra Atacama, can \u2018restart\u2019 or power up the grid independently of a diesel generator, known as a \u2018black start\u2019. This is particularly helpful in the event of power outages.<\/p>\n

    Additionally, a venue\u2019s standing in terms of Corporate Social Responsibility (CSR) is immediately enhanced through the adoption of clean technology, such as the Atacama solar+storage system. Tierra Hotels has already been recognised as the Most Sustainable Tourism Company in Chile, on the back of its innovative deployment of solar and the use of local and eco-materials in its design and construction.<\/p>\n

    Two German companies designed and executed the system: Kraftwerk the solar PV, and Qinous the battery storage. In fact, the project itself was executed in two stages.<\/p>\n

    First, in 2013, PV project developer and turnkey installer Kraftwerk designed and constructed a 23 kilowatt-peak (kWp) PV system, roughly 100 solar panels \u2013 and integrated the solar energy seamlessly with the Tierra Atacama diesel genset system. This delivered diesel savings of around 15% a year.<\/p>\n

    While there are often many questions and some hesitation about adopting relatively new technologies, the smooth operation and stable electricity supply of the solar system at stage one gave Tierra Hotels the confidence to upgrade their onsite solution and add the battery. And without adding battery storage, the solar system would always be limited as to how much diesel could be replaced while ensuring continuous power supply.<\/p>\n

    This year, the operators contracted Kraftwerk to increase the solar share with a further 133 kWp of solar panels and with battery storage. Kraftwerk commissioned smart-battery solution provider Qinous<\/a> to design, produce and install a 335 kWh battery system \u2013 and to integrate it with the PV and diesel generators.<\/p>\n

    The result of the upgrade is that the Tierra Hotel can now completely switch off its diesel genset during the day, and for a few hours each night. The diesel savings are also expected to be greatly increased \u2013\u00a0 to an incredible 60-65% a year.<\/p>\n

    \u201cOne of our core values in Tierra Hotels is the protection of our environment, that\u2019s why we want to provide the best experience and service with minimal disruption,\u201d says Miguel Purcell, the Executive Director of Tierra Hotels. \u201cWe\u2019ve saved a significant amount of diesel over the past couple of years and have substantially decreased our carbon footprint.\u201d<\/p>\n

    While the Tierra Atacama resort is an island surrounded by sand, island hotels and resorts scattered throughout the world\u2019s oceans are also prime sites to benefit from today\u2019s solar+storage systems.<\/p>\n

    \u201cThe Qinous battery systems arrive on site fully assembled and are rigorously tested before shipment,\u201d says Founder and Managing Director Steffen Heinrich. \u201cWe\u2019ve shipped them to the Australian Outback, African villages, and even high up in the Alps, and they can be on site, installed and up and running in a matter of days.\u201d<\/p>\n

    An additional advantage of the system is that it can provide detailed data as to the operation not only of the battery itself, but of the energy system at the site. The Qinous portal, from which the Tierra Atacama data above was collected, can help facility owners and operators get a deeper understanding of their energy system \u2013 allowing for the optimisation of energy use and further savings into the future.<\/p>\n

    This month, the company completed the installation of a 61 kWh battery system at the Hochleckenhaus shelter high in the Austrian Alps. The battery unit was transported to the site by helicopter. It was coupled to a 17 kWp solar PV plant.<\/p>\n

    Once installed, the battery solution allows Austrian Alpine Association (\u00d6AV) not only to observe the operation of their solar+storage array, but also monitor and log gas and water consumption within the mountain hut. Visitors then can be billed for their consumption accurately and with complete certainty.<\/p>\n

    \u201cWhat impressed us about the Qinous solution was its reliability and its modern, holistic and flexibly expandable concept,” says Peter Hochleitner, chairman of the \u00d6AV’s V\u00f6cklabruck section. \u201cAs alpine associations, we place particularly high demands on energy supplies from renewable sources in huts that carry our environmental seal of approval.\u201d<\/p>\n
