Product description

Enerwhere designs, builds, and operates the world’s most advanced hybrid microgrids. We aim to reduce our client’s carbon emissions and fuel costs for generating power, while enhancing their reliability and electrical safety. We do this through the use of cutting edge renewable and storage technologies, bespoke engineering, and through the collection and analysis of big data

In order to propose a highly optimised hybrid system, we need to know the total connected electrical load, and what these loads are (cooling, pumps, tower cranes, lights, etc.) and how often do they run. What is the planned power configuration (generators required). We also ask for a site layout or a sites logistics plan to propose a location for our hybrid equipment, and finally a single line diagram to know where are the possible tie in points. If the project is a brownfield with operational data, fuel and energy consumption, along with maintenance and rental costs are helpful to establish a baseline

Zaya Nurai in Nurai, Abu Dhabi, UAE

Zaya Nurai Island is an award-winning luxury resort island, just off the coast of Saadiyat Island in Abu Dhabi. The island hosts several dozen luxury villas, 5 restaurants, numerous attractions (including a surf pool), as well as a full set of infrastructure with RO plant, STP and staff housing. Due to the off-shore location, the island had been powered by diesel generators for several years. In a quest to reduce the cost and environmental impact of the power generation on the island, Zaya has contracted Enerwhere to supply the power requirement of the island on the basis of a Power Purchase Agreement (PPA).
Enerwhere deployed a customized solar-diesel hybrid system to the island in July 2016, designed to minimize the visual impact on the luxury island atmosphere. The solar plants are largely hidden on the roofs of utility buildings and back-of-the-house areas, with only a low-profile east-west facing solar system visible on the south beach.
The system integrates Enerwhere’s solar generator system with multiple synchronized high-efficiency diesel generators located in a central power station. The power is distributed to the island through a Medium Voltage network. The system also integrates the island’s existing generators as additional backup capacity to provide cost-effective, reliable power around the clock. Additionally, Enerwhere deployed in February 2020 the first near shore open sea floating structure in the region. The solar system is integrated to the hybrid grid of the island. 4,700 tons/year CO2 saved - 1.9 million liters/year Fuel saved - 1,600 MWh/year Solar production.

BESIX in Dubai, UAE

Six Construct, the middle east subsidiary of Belgian construction giant BESIX known for bringing to life iconic landmark projects such as Ferrari World Abu Dhabi, Warner Brothers Theme Park, Burj Khalifa and many more, was awarded the contract for building the Uptown Tower in the Uptown Dubai district planned by Dubai Multi Commodities Centre (DMCC). The tower will stand at 340 meters tall and will be host to an exclusive mix of international Grade A offices, 5-star hotel and associated branded residences. To power their construction activities, Six Construct, like most other contractors in the Middle East, used to rely solely on diesel generators, which are noisy, very expensive to operate and emit harmful emissions.
To provide cost and emissions savings, Enerwhere using its experience and familiarity with loads in the construction industry introduced power management and renewable energy into their power generation mix. The site is now powered by Enerwhere’s solar-diesel-hybrid microgrid, comprising of 500 kWp of solar panels and relies on technology, engineering, and data analysis to deliver clean, renewable and reliable power to site. The system fully powers the site offices, site utilities and even power-heavy applications such as tower cranes, man hoists and pumps via a centralized medium voltage network.
To integrate the solar power into the microgrid, Enerwhere utilizes its proprietary state-of-the-art power management and control system, which provides real-time monitoring of site power requirements and optimizes the solar penetration by controlling the generators, the solar system and the loads. The system has reduced CO2 emissions by over 300 tonnes while providing BESIX cost savings of over AED 200,000 since its commissioning in March 2019. 220 MWh/year Solar production - 1,362 tons/year CO2 saved.

Al Dhafra Recycling industries (ADRI) - Tadweer in Nurai, Abu Dhabi, UAE

Al Dhafra Recycling industries (ADRI) is responsible for the processing of construction and demolition materials across Abu Dhabi, to further produce recycled products suitable for use as road base aggregates, structured and non-structured backfill projects. Due to the remote location of ADRI, the facility relied solely on diesel generators to provide power to jaw crushers, cone crushers, screening plant, conveyor belts and site offices. Aside the increased carbon footprint and the cost involved, ADRI suffered from generators continuously heating up, which resulted in frequent shutdowns culminating in loss of power.
Enerwhere first deployed a solar-diesel hybrid at ADRI in January 2018. Trackers were later mobilized on site to increase vastly the solar share. The usage of 1.5-axis trackers enables an increase in 10-15% of solar energy harvested, being not as costly as a dual-axis tracker but superior in performance to a single-axis tracker. Maximum energy from the sun is harvested at each point in time during the day, hence matching better industrial load curves. Ultimately, a total of 114 trackers along with an Energy Storage System (ESS) ensure sustainable microgrid operation, where Enerwhere's custom built Energy Management System (EMS) is utilized to control the energy flows within the system and optimize overall fuel efficiency of the plant, allowing to reach up to 80% penetration of renewable power generation.
This power is supplied on the basis of a Power Purchase Agreement (PPA) and invoiced monthly on a kWh basis, eliminating the financial burden of a heavy initial investment. 125,000 USD/year Saved on energy cost - 1,510 tons/year CO2 saved
