180.000 DKK to literature: Facebook Odense Data Center donates to libraries in Odense

Facebook Odense Data Center has donated DKK 180,000 to Odense Libraries and to the Citizen Service Center, to cover the costs associated with increased digital lending during the corona crisis.


Since the lockdown measures due to COVID-19 were introduced in early March, the citizens of Odense have been lending books, audiobooks, and music digitally from Odense Libraries.  The libraries have experienced a 200-300% increase in e-book and audiobooks lending. This has led to increased cost in keeping up with the spikes in demand for digital services for the libraries.

Facebook Odense Data Center has stepped up and decided to support the local libraries by donating 180.000 DKK, which will help the libraries in Odense to maintain their digital services, as well as build upon expanding their digital platforms for future demands.

“ We are grateful for Facebook’s support in our digital library services. This donation shows that their presence in Odense has a wider impact, stretching to necessary basic functions in our community, which benefits many citizens here”, said Kent Skov, the Director of Odense’s Libraries.

Supports digital platforms

Facebook, who announced their Odense data center build in 2017, are ready to support digital initiatives wherever they can.

“Facebook is about connecting people and communities, as well as utilizing the power of technology. When we found out that the lockdown measures increased the interest in digital content in Odense, but added to the costs for the libraries, we stepped up to the occasion to support Odense Libraries and the Citizen Service Center”, said Carsten Sørensen, Site Manager at Facebook Odense Data Center.

For the data center,  access to digital content especially for students is viewed as a vital function to maintain their studies from home.

Odense Libraries, who has around 500,000 yearly visitors on their website, and lending around 2 million books, are set on expanding the digital platforms, and donations such as the one from Facebook helps Odense Libraries to achieve this after the crisis.

”We are committed to play a positive role and invest in the long-term vitality of the community in which we operate in”, concludes Carsen Sørensen.

Data centers as a source of flexibility for low-carbon energy system

Janne Paananen, Technology Manager, Critical Power Solutions, Eaton, EMEA, shares his views on how data centers can be a source of fast frequency response and virtual inertia.

Originally released in: Danish Data Center Market Outlook 2020

Data centers and ICT infrastructure are using vast amount of energy to provide digital services for societies, that are used mainly for our entertainment. Even though new technologies are more energy efficient, the even faster growth in digital services and data usage outgrows the gains in energy efficiency, which leads to increasing power demand. As a result, the global energy demand by data centers and ICT is expected to grow in the upcoming years, making it more difficult to meet our targets to reduce GHG-emissions.

The big global data center companies are amongst the largest global users of renewable energy and frequently announce new PPA’s, which support their goal to become carbon neutral, or even negative, in the future. This drives to higher penetration of wind and solar power to grid and reduces emissions. While doing so, it also poses a challenge for the TSO’s, whose responsibility is to maintain system balance and reliability.

Firstly, the intermittent nature of variable renewable energy (VRE) requires more flexibility and reserves in the system to compensate for variations in wind and solar power generation. The changes in wind and weather conditions can be forecasted rather well and the time scales are from minutes to hours or days.

Secondly, the wind and solar are non-synchronous, meaning that they do not have a spinning mass directly coupled to system voltage and frequency. As a result, the inertia that is formed by all the spinning mass in the grid, is reducing. Inertia has a stabilizing effect to frequency variations, caused by imbalances between demand and supply, and it plays a crucial role especially during contingency events when a sudden loss of generation capacity from the system occurs. In a system with low inertia, there’s less stabilizing force, and frequency variations are faster and larger, where traditional generation does not respond fast enough to contain the frequency. This asks for new types of frequency containment reserves, such as Fast Frequency Response in the Irish and Nordic markets. These are typically based on power electronics and batteries or fast load shedding.

Leveraging UPS tech to balance sustainable energy demand

Without fast enough response from the system, the amount of renewable generation may need to be limited, leading to curtailment of wind and solar power. It does not matter how many PPA’s are in place, if the system cannot tolerate more non-synchronous generation from a reliability aspect. The amount of renewable generation may be limited due to system capabilities.

Opposite to demand response, FFR type services are not energy intensive or require large energy storage. Those activate rarely, for some seconds, and are therefore suitable also for traditional batteries in a data center. Other types of frequency containment, and demand response, requires other types of batteries, such as lithium technology aimed for cyclic use.

Suitability of a static UPS in a data center for frequency regulation has been proven in various pilots conducted in Europe and US. When equipped with correct control algorithms, the demand can be seamlessly and quickly controlled between mains and batteries, whilst remaining connected to the grid, and this can be load independent. Furthermore, the amount of energy used from batteries can be limited to provide enough back-up time for critical loads. Thus, with the correct technology, the benefits of the asset can be maximized, in a fail-safe manner.

Above technology enables data center owners to achieve better value from their assets. By leveraging modern UPS technology and its energy management capabilities, it can be used to achieve savings in energy costs through demand response, or to generate additional revenue by participating in frequency regulation. In respect to UPS system OPEX and TCO, this can turn things upside down, and a UPS can generate income instead of being an expense. From another point of view, the overall cost of energy can be reduced by new revenue streams from energy markets.

And as the most important aspect, by providing necessary flexibility and fast response, the data centers can help to increase penetration of renewable energy in the grid, making electricity cleaner for everyone, while helping to maintain grid reliability. This also has positive impacts on cost of energy, since leveraging existing assets, instead of building new separate reserve units, reduces the investment cost associated with future low carbon power system, resulting in lower energy prices and tariffs.

How data centers can green the grid and lead the green transition by example

Rasmus Lildholt Kjær, CEO at Better Energy, shares his views on hyperscale data centers’ contribution to the green energy mix in Denmark

Originally released: Danish Data Center Market Outlook 2020

The world is in the midst of a climate crisis and change is therefore a necessity. We must significantly reduce our CO2 emissions by 2030 to avoid a climate disaster. CO2 emissions come primarily from fossil fuels and the transition to renewable energy is crucial.

The transition to renewable energy can only be achieved by adding new renewable energy to the energy system. Only by adding new renewable energy can fossil fuels be phased out. Until now, the supply of renewable energy has been driven by government support. The granting of this support has had the effect of ‘additionality’, the fact that new renewable energy plants have been built and new renewable energy has been added to the energy supply. Government support has had the effect of adding new renewable energy.

At the same time, the renewable energy supplied through government support has received certificates of origin which have been used by energy suppliers to document the sale of renewable energy to their consumers. However, this sale of renewable energy and certificates of origin has had no effect of ‘additionality’. Two parties are simply trading in pre-existing renewable energy. It has had no effect of increasing the supply of new renewable energy.

When consumers buy existing renewable energy for their electricity supply, they just take it away from other consumers, and the net result is the same. New renewable energy is not added, and CO2 emissions are not reduced. They just use the renewable energy that taxpayers have already paid to add through government support.

Hyperscalers leading the way

An interesting and innovative aspect of the power purchase agreement (PPA) between Better Energy and Google for the 50 MW Næstved solar plant is that it is the first Danish PPA to have a 100% ‘additionality’ effect. The solar plant does not receive government support, and it is the PPA alone that has had the effect of ‘additionality’. It is therefore the PPA that has had the effect of increasing the supply of new renewable energy. In addition, it was also was critical to the Google PPA that the new solar power plant was located in Denmark so that the positive additionality effect goes into the same country.

The Google PPA is a game changer in the renewable energy transition. Consumers of energy can now drive the transition to renewable energy. Going forward, data centers and other major energy consumers can make a world of difference by choosing to be supplied with new renewable energy that does not receive government support.

Hyperscalers can now demonstrate real climate action by sourcing new subsidy-free green power that helps, not hinders, progress towards national climate goals. Going green today is no longer an obstacle, but an opportunity – a rare chance to radically change the way society is powered.
