#1 - The New Age of Electrification
I've spent most of my career trying to predict what is going to happen when markets face periods of profound change - it is a important skill for an entrepreneur - and the April 2025 Iberian grid blackout got me thinking about the increasingly vital role electricity plays in our daily lives and the growing importance of grid security. Which prompted the question, what does the New Age of Electrification really means for us?
My conclusion is that this isn't just a new chapter in the energy transition, and it isn't simply a story about more electricity. It’s a story about a completely different electricity system - because as we electrify almost everything, we are fundamentally changing the ways and the uses for which the global economy consumes energy. Understanding the challenges and opportunities stemming from this revolution is something I want to explore in the coming weeks.
Everything is Changing
For most of the industrial era, energy systems were built around large, centralised sources of relatively predictable energy: coal, gas, oil, nuclear and large hydroelectric plants. Electricity travelled predominantly in one direction, from large generators through transmission and distribution networks to passive consumers, and the management challenge was principally one of balancing a relatively predictable demand profile against controllable generation.
In the New Age of Electrification that model is being replaced rapidly, and grids are facing immense pressures as they transition to meet new demands as they manage the transition from fossil-fuels to renewable generation, while simultaneously scaling their generation capacity, transmission & distribution networks, while also scaling storage flexibility, and resilience, now managed by an increasingly automated digital infrastructure.
What’s Driving these Changes?
Three independent but interlinked forces are simultaneously at play here: (i) the first is the elimination of fossil fuels from the generation of electricity; (ii) the second is the electrification of things which were previously powered by fossil fuels and; (iii) the third is growing demand, driven by an expanding global population, industrial growth, heat pumps, air conditioning, data centres and artificial intelligence. This fascinating topic will be the subject of a later article.
So, in the face of this rapid broadening of the uses of electricity, it’s no surprise that after years of stagnation, the International Energy Agency (IEA) expects global electricity demand to grow at an average annual rate of nearly 4% between 2026 and 2030, with solar and wind becoming the dominant sources of new generation – and encouragingly 90% of utility-scale renewable projects commissioned in 2025 produced electricity at a lower cost than the cheapest new fossil-fuel plant available in their respective markets.
The Paradox
While the cost of producing abundant clean electricity is becoming increasingly competitive, adapting the electricity infrastructure to renewables is proving to be a significantly complex challenge.
To understand the scope and the scale of this challenge, grids are not simply undergoing a revolution in terms of the sources of their energy, and its transmission and delivery, they are also transitioning from industrial scale power stations to a generation and storage network which comprises millions of distributed assets, which includes intermittent renewable energy generating assets, massive batteries, electric vehicles, heat pumps, flexible industrial loading and highly concentrated new consumers such as hyperscale data centres. And unlike the past, where the flow of electricity was primarily from generator to consumer, increasingly these flows are becoming bi-directional – e.g. EVs and BESS are both buyers and sellers of electricity.
So, despite global energy investment expected to reach $3.4 trillion in 2026, with clean-energy investment reaching approximately $2.2 trillion, grids are struggling to deal with the scaling demand for generation, transmission, distribution, and storage. As an example, grid connectivity is becoming an increasing roadblock, with an estimated 2,500 GW of renewable, storage and large-load projects currently stalled in grid connection queues worldwide.
New Sources of Capital
Another important dynamic which has changed rapidly is the source of capital funding in the energy sector. Attracted by energy’s increasingly green credentials, distributed infrastructure , and growing market complexity and volatility, private capital from impact investors, infrastructure funds, private equity, pension funds, and sovereign investment funds is increasingly replacing traditional public utility equity capital.
With smarter capital arriving, the operating models of energy asset owners are evolving rapidly, and energy markets are increasingly taking on the characteristics of sophisticated financial markets, with growing reliance on advanced trading software to manage growing market volatility.
With this changing ownership model comes an increasing focus on asset performance, optimised investment returns around finite investment horizons, increasing use of leverage, and greater focus on portfolio optimisation, transparency and auditability.
Software & Automation
To deal with the huge challenges of transitioning to an increasingly distributed grid infrastructure, AI, digital twins, and software are rapidly moving in the direction of autonomous grids, by transforming grids from centralised, hardware-defined systems into distributed, software-defined, automated operating environments.
In the process the role of software is rapidly evolving from monitoring and reporting towards prediction, optimisation, and autonomous decision-making, including the ability to continuously monitor and coordinate physical assets, while aware to market conditions, asset degradation, network constraints, and customer demand, and the need to deliver increasingly dynamic investment objectives.
Grid Security
While the rapid expansion of electrification is massively positive for the environment, it also serves to make electricity grids highly attractive strategic targets.
In Spain and Portugal the commercial economies of both countries effectively shut down for several days, when their grids went offline in April 2025, and the US Administration recently highlighted the importance of grid security and the country’s ability to generate, store, and transmit electricity to National Security.
As a result, it is vitally important that while reinventing the structure and operation of electricity grids, steps are taken to protect them against a growing number of strategic threats. This will require energy technologies that can be swiftly patched, and increasingly distributed grid assets which are capable of quarantining and controlling disruption to ensure essential services continue to run if the wider grid is disrupted.
Modern, software-defined energy technologies, are designed from the outset to be more security resilient, with restrictions on access and the ability to quarantine equipment infiltrated by cybercriminals. Similarly, the rapid expansion of solar panels and battery storage, both of which rely on software to direct their generation, transmission and distribution (rather spinning turbines or mechanical switches), are also introducing a more sophisticated approach to grid management and security.
As a result, modern grids with generation and storage distributed across many locations, will introduce the flexibility to operate as part of centralised meshed grid systems, or to operate as separate micro grids, ensuring continued local operation during times of crisis.
The Operating Model of the Future
The operating model of the future will therefore be less about controlling a single system and more about coordinating a living network. Grid operators will need to balance physical infrastructure with digital intelligence, combining long-term planning with rapid, local decisions. The most valuable assets may not always be the largest generators. They may be the platforms, connections and flexible resources that allow the system to respond when conditions change.
This shift also changes the meaning of reliability. A reliable grid is not simply one that delivers power under normal conditions. It is one that can anticipate stress, isolate problems, recover quickly and learn from each event. That requires better visibility across transmission and distribution networks, clearer signals for consumers and stronger collaboration between utilities, technology providers, investors and public institutions.
The transition will not follow one universal path. Dense cities, rural regions, industrial clusters and remote communities will face different constraints and opportunities. Some will prioritise new transmission; others will focus on storage, demand response or local resilience. The common requirement is an electricity system designed to evolve rather than remain fixed.
Electrification is often described as a race to build more clean generation. It is also a redesign of the relationship between energy, infrastructure and society. The grids that succeed will be those capable of connecting more resources, making better use of data and giving more participants a meaningful role. The result may be more complex than the system we inherited, but it can also be more responsive, efficient and resilient.
Summary
The global electricity system is rapidly becoming distributed, variable, and enormously more complicated.
The challenge is not simply about embracing renewables or building a new generation of power stations - we are rebuilding the energy operating system of the global economy.
Growing reliance on electrification in an increasingly security challenged world means that measures to ensure grid security will be paramount, with meshed networks of microgrids the way forward.
Given increasingly complex management challenges, increasing autonomous grid management is inevitable.
The biggest energy story of the next twenty years won't be about any single technology it will be about how we make many new technologies and millions of individual energy assets work together.
Mass electrification present extraordinary challenges and extraordinary opportunities for investors, utilities, technology companies, and entrepreneurs.
In the coming weeks I plan to explore these challenges and opportunities in more detail...
