Renewables dominated global power additions in 2021

960 640 Stuart O'Brien

Data released by the International Renewable Energy Agency (IRENA) shows that renewable energy continued to grow and gain momentum despite global uncertainties.

By the end of 2021, global renewable generation capacity amounted to 3 064 Gigawatt (GW), increasing the stock of renewable power by 9.1 per cent.

Although hydropower accounted for the largest share of the global total renewable generation capacity with 1 230 GW, IRENA’s Renewable Capacity Statistics 2022 shows that solar and wind continued to dominate new generating capacity. Together, both technologies contributed 88 per cent to the share of all new renewable capacity in 2021. Solar capacity led with 19 per cent increase, followed by wind energy, which increased its generating capacity by 13 per cent.

IRENA Director-General Francesco La Camera, said: “This continued progress is another testament of renewable energy’s resilience. Its strong performance last year represents more opportunities for countries to reap renewables’ multiple socio-economic benefits. However, despite the encouraging global trend, our new World Energy Transitions Outlook shows that the energy transition is far from being fast or widespread enough to avert the dire consequences of climate change.”

“Our current energy crisis also adds to the evidence that the world can no longer rely on fossil fuels to meet its energy demand. Money directed to fossil fuel power plants yields unrewarding results, both for the survival of a nation and the planet. Renewable power should become the norm across the globe. We must mobilise the political will to accelerate the 1.5°C pathway.”

To achieve climate goals, renewables must grow at a faster pace than energy demand. However, many countries have not reached this point yet, despite significantly increasing the use of renewables for electricity generation.

Sixty per cent of the new capacity in 2021 was added in Asia, resulting in a total of 1.46 Terawatt (TW) of renewable capacity by 2021. China was the biggest contributor, adding 121 GW to the continent’s new capacity. Europe and North America—led by the USA—took second and third places respectively, with the former adding 39 GW, and the latter 38 GW. Renewable energycapacity grew by 3.9 per cent in Africa and 3.3 per cent in Central America and the Caribbean. Despite representing steady growth, the pace in both regions is much slower than the global average, indicating the need for stronger international cooperation to optimise electricity markets and drive massive investments in those regions.

Highlights by technology:

  • Hydropower: Growth in hydro increased steadily in 2021 with the commissioning of several large projects delayed through 2021.
  • Wind energy: Wind expansion continued at a lower rate in 2021 compared to 2020

(+93 GW compared to +111 GW last year).

  • Solar energy: With an increase in new capacity in all major world regions in previous years, total global solar capacity has now outgrown wind energy capacity.
  • Bioenergy: Net capacity expansion increased in 2021 (+10.3 GW compared to +9.1 GW in 2020).
  • Geothermal energy: Geothermal capacity had an exceptional growth in 2021, with 1.6 GW added.
  • Off-grid electricity: Off-grid capacity grew by 466 MW in 2021 (+4%) to reach 11.2 GW.

Flow informs to maximise energy efficiency and savings

960 640 Guest Post

Being able to see how system components are performing in real-time is crucial if energy managers are to reduce costs and improve environmental performance of buildings. Without information on fluid flow, across the system, it’s difficult to diagnose and optimise efficiency. With accurate flow information, the picture changes entirely. 

Armstrong Fluid Technology has developed Active Performance Management to help optimise HVAC systems at any stage of a building’s life-cycle, responding to changing HVAC requirements. The combination of smart commissioning with real-time alerts and system transparency addresses performance drift and maintains occupant comfort. With Active Performance Management you can make annual energy savings of up to 40%.

One of Armstrong’s Active Performance Management solutions is Pump Manager, which ensures that pumps continue to operate efficiently and reliably throughout their complete lifecycles. Pump Manager is a cloud-based application that uses the embedded intelligence and connectivity of Armstrong Design Envelope pumps to provide performance reports to system operators. With this information, operators can make changes and address issues to optimise HVAC performance. 

Online trending and analysis across multiple parameters on single pumps, or on an aggregated basis for multiple pumps, assists in identifying performance degradation and facilitates a predictive and proactive approach. Pump Manager will, for example, report issues such as excessive vibration, pump in hand, risk of cavitation or a dead head should they start to occur.

Compatible with industry-standard BMS, EMS or CMMS solutions, Pump Manager helps reduce operating costs by providing data to support continuous optimisation of pump performance. Pump Manager also increases pump availability and reliability, reducing unexpected failures and providing early problem detection. Lastly it helps organisations report their energy use and environmental performance.

Energy Monitoring and Targeting – Mapping data to gain more meaning

960 640 Guest Post

Gathering energy data to measure the performance of your building estate is commonplace. With rising energy costs and a move towards reducing carbon it is of course important to monitor and report on the energy usage across your building estate. Automatic Monitoring and Targeting (AM&T) is a standard process for energy reduction, but what if there was another way?

A more intelligent approach to energy use in buildings

What if you were able to map your energy usage with occupancy usage, to tailor building services to demand? Resulting in an optimised, more efficient building. What if you were able to collate data from different building services to provide a more intelligent approach to usage? For example, you could map the BMS data with your lighting and your meeting room booking system. In this instance you could manage the energy around meeting rooms in an office location more effectively. When not in use you could power off all appliances in that space. You could even instruct for cleaning to be put on hold. But when a meeting is scheduled you could automate the HVAC to bring the room up to temperature in time for the start of the booking, you could initiate the lighting and instruct for cleaning to take place afterwards. Additionally, if the meeting was cancelled yet not updated on the system, the space if not entered in the first 15 minutes, could be relaxed and automatically made available for others whilst also saving valuable consumption. By mapping different services within one building you are then able to be smarter with your energy and service provision.

The AXON platform gathers big building data, to provide visualisations and reporting on energy, consumption, lighting, environment and occupancy, for estate performance analytics at all levels. By seamlessly integrating your building data onto the technology independent AXON platform you can optimise the performance of your estate today. There is no need to change or install different plant equipment, AXON is brand agnostic and can be connected to your existing BMS.

Providing fair and transparent recharging of utility costs to occupants

Another added benefit to gathering big building data is the ability to accurately bill energy costs to tenants, known as intelligent apportionment. With AXON this process can be automated and is something we have done for buildings such as London Bridge City estate including Hays Galleria, Cottons Centre, No 1 London Bridge City and 2 & 6 More London. Broadgate Estates were looking for a platform that was technology independent, a platform that could integrate disparate data streams from the technologies installed within the estate. Broadgate Estates wanted to reduce the overall energy consumption of their clients’ building stock, whilst also provide fair and transparent recharging of utility costs to occupants. 

Broadgate Estates have experience in using the disparate technologies within a building to reduce consumption and deliver occupier bills. Yet existing solutions, in their opinion, were not integrated or automated sufficiently; or there was a commercial bind between the software platform and a specific brand of hardware. Importantly they wanted to combine data from both the energy management system (EMS) and BMS to identify energy reduction opportunities, to then also prove the outcome of the remedy.

Working with AXON they were able to achieve a significant reduction in operational hours per annum resulting in identified energy savings of 1,935,876 kWh.

The energy storage market ‘paving the way for next energy revolution’

960 640 Stuart O'Brien

The energy storage market has caught the eye of a number of stakeholders involved in the power industry, leading to its considerable growth and opening the way for the next energy revolution.

So says GlobalData’s latest thematic report, Thematic Research: Energy Storage, which highlights the present scenario and emerging market trends across electrochemical, mechanical and thermal energy storage.

The report says demand for energy storage system (ESS) devices in the power sector is increasing rapidly, particularly after the increase in the renewable energy integration into the grids. Intermittent power supply led to demand for the storage of electrical energy and supply during peak load periods. ESS devices can help make renewable energy – whose power output cannot be controlled by grid operators – smooth and dispatchable.

With the global energy storage market becoming one of the rapidly growing segments within the renewable power mix, GlobalData says equipment manufacturers or technology providers of energy storage technologies are focused on innovating their energy storage solutions and offering advanced energy storage systems.

Sneha Susan Elias, Senior Analyst of Power at GlobalData, said: “Battery energy storage system (BESS) is regarded as a crucial solution for overcoming the intermittency limitations of renewable energy sources (RES). The battery energy storage market reported cumulative deployment of 4.9 GW at the end of 2018 and is expected to reach 22.2 GW in 2023, with the US accounting for 24.7% of the global capacity. The deployment is expected to grow, due to a large number of countries opting for storage utilization to support their power sector transformation.

“The expansion in battery manufacturing capacity and falling costs resulting from the electric vehicle (EV) industry are driving growth in energy storage services and new markets. This fall in battery prices has favored the battery energy storage market and has speeded the deployment of energy storage projects globally.

“Currently, lithium-ion (Li-ion) batteries dominate the electrochemical energy storage market but other battery energy storage technologies such as sodium-sulfur (NaS), lead-acid and flow batteries are now getting deployed. While, thermal energy storage utilizing molten salt is among the most widely used technology in association with concentrated solar power (CSP) projects, among mechanical energy storage technologies, pumped hydroelectric storage systems is among the most mature energy storage technologies and offers a number of benefits such as energy-balancing, stability, storage capacity, along with ancillary grid services which include network frequency control and reserves.”

APAC shifting towards renewable energy auctions

960 640 Stuart O'Brien

Asia Pacific (APAC) countries are adopting several strategies and roadmaps to achieve the renewable energy targets designated by their governments.

Countries such as India, Kazakhstan, Indonesia, Pakistan and Taiwan have implemented auctions to drive their renewable energy market, according to GlobalData. 

The company’s latest report ‘Asia Pacific Renewable Energy Policy Handbook 2019’ reveals that regulatory framework and policies of the APAC countries are aiming to achieve a strong growth in the renewable energy market.

Piyali Das, Power Analyst at GlobalData, said: “Auctions are the major mechanism in APAC driving the renewable energy sources in most of the key countries, with India being the most prominent in implementing auction plans to award 80 gigawatts (GW) of solar and 28 GW of wind projects between 2018 and 2020.”

Feed in tariffs (FiTs) play a role in enhancing the renewable energy market in APAC. In countries such as Australia and India, FiTs to renewable projects is a provincial or state subject.

Pakistan has been providing FiTs in renewable sources such as solar, wind and small hydro since 2015. Taiwan provides FiT for renewable systems and is subject to annual revision.

Piyali concluded: “The regulatory framework and policy structure, supporting renewable energy resources in various APAC countries, has led to significant development in the renewable energy market. China, India, Japan are some of the leading nations in renewable energy growth trajectories. In the wake of growing energy security and environmental concerns, most APAC countries are expected to strengthen their renewable energy mechanisms, which will help the Asia Pacific renewable energy industry to maintain growth in the coming years.”

Global battery energy storage market to grow to $13.13bn

960 640 Stuart O'Brien

The global battery energy storage market will grow to $13.13bn by 2023, with Asia-Pacific (APAC) and EMEA the dominant markets.

The report from GlobalData reveals that a fall in technology prices and increasing pace of development in the power market are the primary driving factors for the growth.

APAC will continue to be the largest market reaching $6.05bn in 2023, as countries are increasing investments for improving their grid infrastructure and improving the market structure to attract foreign investments. With respect to technology, Lithium-ion is and will continue to be, the preferred technology for market deployment.

Bhavana Sri, Power Analyst forGlobalData, said: “The US has been the largest market for Battery Energy Storage System (BESS) both in terms of cumulative installed capacity and by market value for projects installed up to 2018 and is likely to continue to lead the market at the country level. The US market for battery energy storage is estimated to reach $2.96bn in 2023, accounting for 23% of the global market.”

Asia-Pacific was the largest market for battery energy storage systems and it accounted for 45% of the global market installed capacity in 2018 and the region is also expected to maintain its top position in the forecast period.

With the number of grid-connected renewable electricity generation plants increasing tremendously, countries such as China, India, Japan, South Korea, and the Philippines will focus on frequency regulation in the electric grid to normalise the variation in power generation from renewables.

The EMEA battery energy storage market registered a market value of approximately $1.73bn in 2018 and it accounted for 26% of the global market. The region has strong demand for flexibility, due to technological advancements, evolving market conditions, strong research facilities, and supportive policies. Middle East and Africa are small markets with demand for storage expected to increase once renewable power generation gains significant traction in the market.

The Americas battery energy storage market registered a market value of approximately $1.97bn in 2018 and it accounted for 28% in 2018. The battery energy storage market in the region is growing, with countries such as the US, Chile, Canada and Brazil promoting battery storage installations across consumer segments. Some US states have robust incentive programs, most notably California, which adopted an ambitious target for 1.3GW of energy storage by 2020, which it surpassed and a new target is awaiting approval.

Bhavana Sri concluded: “With countries aggressively promoting the modernisation of grids, and developing their capability to handle the demands of the present and future, batteries are being deployed to support smart grids, integrate renewables, create responsive electricity markets, provide ancillary services, and enhance both system resilience and energy self-sufficiency.“Market conditions are improving and more companies are moving into a decentralised generation, leading to an increase in the onsite deployment of renewables and batteries; as in with micro or mini girds. Supportive policies and high electricity charges are also nudging the market towards renewables and/or storage plus renewables at the end consumer level. As the power sector evolves to accommodate new technologies and adapt to varying market trends, energy storage will play a central role in the transition and transformation of the power sector.”
