Powered by renewables

The transformation of the energy system and shift towards renewables over the next decade could result in growth of 1,000% in solar power and 500% in wind power. This growth will require an increase in energy storage capacity and a flexible grid infrastructure. Energy efficiency will also be a major driver for a clean energy future.

In the Energy business area, we will continue to offer even more advisory, monitoring and certification services to customers around the globe, accelerating the transition to a clean energy future.

GreenPowerMonitor (GPM)

GreenPowerMonitor (GPM), a DNV GL company, consolidated its position as leader of monitoring, control and asset manage-ment solutions for renewable energy plants in 2019. GPM, who in 2018 launched the world’s first data monitoring platform for integrated wind, solar and energy storage systems, is playing an instrumental role in realising the full potential of delivering clean energy, by integrating renewables systems using the latest digital technologies.

In 2019, GPM added 9 GW to its portfolio. Currently, GPM manages 30 GW (21.5 GW solar and 8.5 GW wind) and more than 4,200 facilities worldwide. DNV GL acquired GreenPower-Monitor in July 2016 and today, it is three times bigger than its original size with a bright future ahead.

KEMA Laboratories changed ownership from DNV GL to CESI

In 2019, DNV GL transferred ownership of KEMA Laboratories to technical consultancy CESI. The transfer comprises KEMA and all the high-voltage and high-power testing and inspection activities performed by its personnel in its own laboratories in Arnhem (NL), Prague (CZ) and Chalfont (USA).

All former KEMA advisory employees remain within DNV GL, including those providing all the advisory services as well as DNV GL’s testing and verification services for power failures, battery testing, transformer oil testing and smart grid testing.

Energy storage safety

By 2050, 63% of the world’s electricity will be supplied by solar PV and wind. Integrating renewables into our grid will depend in part on energy storage capacity and flexibility. By 2030, we will need a 50-fold increase in battery production alongside new technology to store excess electric energy. This will also require an increased focus on safety.

In 2019, DNV GL completed an in-depth power failure investigation (PFI) into a major fire at a large-scale South Korean energy storage facility. This was carried out at the request of the facility’s insurer. The investigation allowed the insurer to make an evidence-based pay-out decision. In addition to pinpointing the minor glitch that initiated the failure, the investigation highlighted weaknesses in current approaches to monitoring and prevention systems that make small failures more likely to become major issues.

Smarter audits drive energy efficiency

DNV GL’s analysis of emissions up to 2050 shows that energy efficiency could help reduce the total energy demand by almost 300 EJ/year. This is equivalent to the annual energy use of 833 cities, with the average metropolis using 100,000 GWh per year. In a rapidly shifting energy landscape, one thing is clear: energy demand reduction can be accelerated in the top three highest use energy sectors — buildings, industry and transport — through a greater understanding and use of digital approaches.

DNV GL has developed an energy audit tool to easily audit multiple business sites and help customers save money by optimizing lighting, ventilation, air control and server rooms.

Today, energy audits rely on manual reports that are often carried out by different auditors across multiple sites, which can affect consistency. Using the new tool, best practices can be identified and shared across multiple sites, maximizing the value of the energy audit. The new tool was financed by DNV GL’s global innovation portfolio, an internal scheme intended to fund the development of projects dedicated to digital delivery or data smart services which add value to customers.

Larger wind turbines drive down wind energy costs

Wind energy is rapidly becoming the new norm for power generation. We forecast that wind will deliver 30% of all global electricity production by 2050, with 12% from offshore wind and 18% from onshore wind.

The industry is continuing to optimize turbine types that deliver significantly improved energy production and cost efficiency. In 2019, DNV GL certified Siemens Gamesa’s newest 8 MW off-shore wind turbine. This will be installed in offshore wind parks worldwide, including the 1,400 MW Hornsea 2 project in the UK and the 900 MW Greater Changhua 1 & 2a projects in Taiwan. Large-capacity offshore wind turbines result in improved energy capture per project, i.e. a lower cost per MWh.

Digitalizing traditional operations plays a vital role in the energy transition

The energy industry needs to change rapidly, and must strive to reduce carbon emissions and safeguard the planet for future generations. Transforming traditional operations through digitalization plays a vital role in enabling this change and facilitating the energy transition. DNV GL’s open industry platform, Veracity, continued to add value to customers in 2019 with key projects such as the Cable Lifetime Monitoring Joint Industry Project (JIP CALM). The project was initiated by DNV GL, TNO (ECN), BREM, VanDerHoekPhotonics, and Deltares, in collaboration with 30+ industry partners, to reduce subsea power-cable failures and make offshore wind energy more reliable.

At present, failing subsea power cables are one of the main risks affecting offshore wind farm development and operations. These failures account for approximately 80% of insurance claims in the offshore wind industry. All the JIP participants will share failure data for windfarm, export and interconnector submarine cable systems with the DNV GL project team in secure Veracity data containers for failure root cause analysis. Confidentiality and anonymity will be maintained by creating company-specific containers.

Future-proofing our power system

With 1,000 Smart Cable Guard systems implemented in its power grid, Dutch distribution system operator Alliander has confirmed its commitment to safeguarding the reliability of the power grid in the Netherlands. Smart Cable Guard is DNV GL’s online monitoring tool which uses sensors to monitor and locate weak spots, intermittent faults and partial discharges in power cables, detecting and preventing faults and avoiding disruptive power outages. Alliander has been installing Smart Cable Guard across its medium-voltage cable network since 2017, with DNV GL providing the hardware, support, monitoring services and data analysis.

As the energy sector evolves, the power grid is exposed to a new range of challenges caused by the decentralization and variability of energy generation, the influx of renewable energy and the digitization of the grid. In 2019, DNV GL awarded TenneT a grid readiness verification statement for its Borssele Alpha offshore grid connection system. This is the first offshore grid connection system in the world to receive a grid readiness verification statement. The grid readiness of the Borssele Alpha offshore grid connection system means that the Borssele I and II wind farms can be connected to the Dutch electricity grid. The wind farms, which are due to be commissioned in 2020, will have a capacity of 700 megawatts (MW) and can generate electricity for approximately one million households.

Global expansion of offshore wind

Offshore wind is growing and set to make up 40% of wind pro-duction by 2050. To meet the increasing demand for offshore wind power in the United States, DNV GL established a Renewables Certification office in North America. According to the U.S. Department of Energy (DOE), there is the potential to install 22,000 MW of offshore wind projects in the US by 2030. Much of this activity is taking place in the northeast, with Massachusetts and New York setting aggressive targets and leading the way in opening the market for offshore wind. For this reason, DNV GL selected its Medford, Massachusetts office as the base for its U.S. Renewables Certification services.

Much of the potential development of offshore wind lies in federal waters and thus requires third-party certification for the design, manufacturing and installation of the entire facility, leading to increasing demand for verification services.
