Communications services have become the "fuel" of the 21st century, a necessity of all modern life. Still, while a necessity, communications service providers (CSPs), in telecom (e.g., Verizon, Telefonica), content (e.g., Netflix, Spotify) and cloud (e.g., AWS, Azure) are struggling to stay relevant as they face growing customer demands for bandwidth, secure communications and always on, while fierce competition results with dramatic service price erosion. These accelerating customer expectations are coupled with the need to rapidly adapt new technologies and solutions such as 5G, SDN/NFV and edge data centers, and to increase efficiency by constantly striving to reduce the total cost of operation (TCO).
Powering data centers and server rooms
A clean and secure supply of power is critical to today’s data centers and IT facilities. Any power failure can have a devastating impact on mission-critical servers, communications and data, resulting in downtime and possible loss of critical information. It is critical that loads are protected by UPS systems from electricity downtime and other electric disturbances. Low total cost of ownership (TCO) is one of the main factors when selecting a power backup solution. Having a highly reliable and efficient UPS system which is easy to operate and maintain is essential to any data center – large data centers and edge data centers. While looking to keep operational costs at reasonable levels, server rooms and the data centers’ owners need for power flexibility and scalability has also become critical and is one of the major considerations in designing a data center and choosing their power back up UPS systems.
Data center UPS market size estimated at USD 4 billion in 2019 and will grow at around 3% CAGR between 2020 and 2026, (Global market insights 2019).
The Benefits of Modular Architecture for Data Center UPS Systems
Since their introduction in 2003 modular UPS systems have been proven to be a reliable, cost effective and scalable solution for backing the mission-critical servers, communications and data in small server rooms as well as in large data centers. As the data center market is growing whether it would be through new data centers being built or through scaling of existing data centers, it is evident that modular UPS solutions help in providing high power performance, optimal reliability, and scalability to these facilities, helping them to support the increasing power requirements. The advanced modular UPS technology enables the loads to always be protected by offering, in most cases, hot swappable modules that can be replaced in case of failure while ensuring continuous power to the connected loads. The modular UPS design is also supporting the continuous data centers load expansion by offering modular-level growth. This is done by simply adding power modules to the existing UPS while not requiring any extra floor space, large capital investment and time. In addition to all that, advanced modular UPS systems will also offer the data centers owners the operating cost savings they look for by offering high power efficiency that can reach 99% in ECO mode while ensuring secured power.
Powering Remote Telecom Tower
In rural areas across the globe, telecom towers are essential for connecting millions of people with civil infrastructures and for accessing digital services. These telecom towers, typically of-grid sites, create extensive demand for energy commanding solid power infrastructure that can sustain and scale these ever-increasing power needs.
Typical existing solution for off-grid sites has been mainly based on generating AC power by on-site diesel generators. The main drawbacks of this solution is the continuous need for diesel to be supplied to these remote areas (in some places very expensive and risky) and generators maintenance that needs to be carried out at fixed intervals.
Both drawbacks are minimized by adding green energy sources, mainly solar panels, and power storage capacity, sized in such a way to optimize the added CAPEX versus the saved OPEX. In many countries in Africa, the trend of harvesting solar energy with some storage capacity is becoming more and more the solution of choice.
WW, in 2019, there were about 325 thousand “bad-grid” and “off-grid” sites, about 70 thousand of them in Sub-Saharan Africa. Some other off-grid sites, such as train signalling are candidates for similar solutions.
