Exploring the Impact of China’s Smart Grid Projects

The Chinese government has been an early pioneer of smart grid technology. Since embarking on its national smart metering project at the turn of the decade, more than 200 million new electricity meters have already been deployed across China.

However, according to the latest market study by ABI Research, only around 50 million have so far been connected with bi-directional communication that can support true smart meter capabilities -- such as 'demand response' measurement.

In short, this key smart meter project has not been that intelligent -- relatively speaking. But it is set to get smarter, and that means another wave of opportunity for utility industry technology providers.

China’s smart meter rollout is a key deployment representing a significant share of smart meter shipments and investment worldwide. Furthermore, connectivity technology semiconductor providers -- such as ST Microelectronics, Silicon Labs, and Atmel -- are likely to benefit.

Smart meter vendors -- including Echelon, Siemens, and Landis+Gyr -- are also anticipating an uplift from these projects. Now the program is reaching a key stage where connectivity will come to already deployed and new electricity meters alike.

Increasingly, that connectivity will be bi-directional as China’s utilities’ smart grid plans expand to manage smart meter use as well as collect usage data. Investment to deliver bi-directional communications will also bring a further wave of competition from Chinese and overseas technology providers.

"Existing meter specifications have ensured meters deployed over the past five years can be upgraded to support bi-directional connectivity. This combined with a recent commitment to consider wireless as well as PLC connectivity, means that there is a growing opportunity for existing and new connectivity hardware providers," says Jonathan Collins, principal analyst at ABI Research.

To date, meter deployments have so far been dominated by Chinese meter manufacturers, but components often leverage technology and products from overseas suppliers.

The shift to greater connectivity provides further potential for non-Chinese players to see their technology included and many suppliers are looking to partner with Chinese meter manufacturers to enable this transition.

The next 12 months heralds a key period of technology assessment that will drive new industry partnerships as players bid to gain greater traction in the Chinese market.

So far, within the smart meter rollout by China’s State Grid Corporation of China (SGCC) and Southern Grid Utilities, new meters have ranged from unconnected to single direction communication. And, one-way communication is only suitable for less complex applications -- such as remote meter readings.

Software-Defined Infrastructure: The Platform of Choice

As more organizations adapt to a hybrid working model for their distributed workforce, enterprise CIOs and CTOs are tasked with delivering new productivity-enabling applications, while also seeking ways to effectively reduce IT cost, complexity, and risk. Traditional IT hardware infrastructure is evolving to more software-based solutions. The worldwide software-defined infrastructure (SDI) combined software market reached $12.17 billion during 2020 -- that's an increase of 5 percent over 2019, according to the latest market study by International Data Corporation (IDC). The market grew faster than other core IT technologies. The three technology pillars within the SDI market are: software-defined compute (53 percent of market value), software-defined storage controller (36 percent), and software-defined networking (11 percent). "Software-defined infrastructure solutions have long been popular for companies looking to eliminate cost, complexity, and risk within their data cente

Digital Identity Verification Market to Reach $16.7B

As more enterprise organizations embrace the ongoing transition to digital business transformation, CIOs and CTOs are adopting new technologies that enable the secure identification of individuals within their key stakeholder communities. A "digital identity" is a unique representation of a person. It enables individuals to prove their physical identity during transactions. Moreover, a digital identity is a set of validated digital attributes and credentials for online interactions -- similar to a person's identity within the physical world. Individuals can use a 'digital ID' to be verified through an authorized digital channel. Usually issued or regulated by a national ID scheme, a digital identity serves to identify a unique person online or offline. Digital Identity Systems Market Development Complementary to more traditional forms of identification, digital identity verification systems can enhance the authenticity, security, confidentiality, and efficiency of

Global Pandemic Accelerates the Evolution of Transportation

Given the current trends across the globe, organizations that depend upon the continued growth of personal vehicle ownership will need to consider a plan-B scenario. While some companies will be able to adapt, others may find that their traditional business model has been totally disrupted. According to the latest worldwide market study by Juniper Research, Mobility-as-a-Service (MaaS) will displace over 2.2 billion private car journeys by 2025 -- that's rising from 471 million in 2021. Juniper believes that for MaaS to enjoy widespread adoption, subscription or on-the-go packages need to offer a strong combination of transport modes along with feasible infrastructure changes, high potential for data collection and low barriers to MaaS deployments. Mobility-as-a-Service Market Development The concept of MaaS involves the provision of multi-modal end-to-end travel services through a single platform by which users can determine the best route and price according to real-time traffic
