The term “baseload power” gets thrown around a lot in debates over the future of energy. But where did this concept come from, and does it still matter in an age defined by solar panels, wind turbines, batteries, and smart grids?
What Is Baseload Power?
Baseload power refers to the minimum level of demand on an electrical grid over a 24-hour period. To meet this constant demand, traditional energy systems relied on large, always-on power stations like coal, nuclear, and large hydro. These power plants were designed to run continuously, delivering a steady and predictable supply of electricity.
These systems were favored for several reasons:
- Stability: They provided consistent output.
- Scale: Massive capacity from a single facility.
- Economics: High upfront costs but low marginal operating costs.
The Origins of Baseload Thinking
The concept emerged during the 20th century when grid planning revolved around predictable demand curves and centralized supply. Grid operators categorized power needs into “baseload” (always needed), “intermediate,” and “peaking” (only needed during demand spikes). Coal and nuclear, being cheap to run continuously, became the go-to for baseload. Natural gas filled in the peaks.
This led to a rigid structure:
- Baseload = always on (coal, nuclear)
- Peaking = flexible but expensive (gas)
Why the Old Model No Longer Fits
The global energy system has evolved dramatically:
1. Demand is Dynamic
With smart meters, EVs, and responsive appliances, demand can now be shaped in real time. In fact, dynamic pricing and demand response programs have already proven their value in places like California, the UK, and Australia, where they’ve helped stabilize grids during extreme events.
2. Supply Is Decentralized and Variable
Renewables like solar and wind are now the cheapest forms of new energy in many regions. According to the IEA, solar is now the “cheapest electricity in history” in some locations. Their output is variable but increasingly predictable with advanced weather forecasting and grid integration.
3. Storage Changes the Game
Battery energy storage systems (BESS) let us store excess renewable energy and release it when needed. Lithium-ion battery costs have dropped over 90% in the last decade, and grid-scale storage is scaling fast. This flattening of the supply curve makes renewables more dispatchable and responsive.
4. Flexibility Is the New Priority
Modern grids need fast, adaptable sources of power—not slow, rigid ones. Flexibility, not baseload, is the core of reliability in the 21st-century grid. Technologies like pumped hydro, BESS, and demand-side flexibility are proving more effective at meeting today’s grid challenges.
Debunking the Baseload Myth
The fossil fuel lobby often invokes “baseload” to argue that renewables can’t be reliable. But this is misleading. The real requirement is not for baseload power—it is for reliable power. And we now have the tools to provide that:
- Renewables
- Battery storage
- Vehicle-to-grid (V2G) EV systems
- AI-powered grid management
- Demand-side response programs
Critics sometimes argue that thermal plants provide critical grid inertia, helping to stabilize frequency. But new technologies like synchronous condensers and inverter-based resources (IBRs) are filling that role, allowing high-renewable grids to maintain or exceed traditional reliability standards.
As Tony Seba and others argue, baseload is a relic from an era of centralized, inflexible power. It’s the steam engine of energy planning—useful in its day, but now overtaken by superior alternatives.
Policy Is Catching Up
Regulators worldwide are adapting. In the U.S., FERC Order 2222 opens wholesale markets to distributed energy resources. In Europe, flexibility markets and capacity auctions reward responsiveness over rigidity. Policy is aligning with technology—and accelerating the transition.
A Smarter Grid for a Decentralized Future
We’re entering a future where:
- Solar dominates daytime generation
- Wind complements solar at night and across seasons
- Storage fills in the gaps
- EVs act as mobile batteries
- AI balances the grid in real-time
In this new paradigm, “baseload” becomes a meaningless term. What matters is resilience, flexibility, and cost-effectiveness—all achievable without clinging to outdated coal or nuclear infrastructure.
TL;DR: Baseload is out. Flexibility is in. Renewables + storage + AI = reliable, modern power. It’s time to retire old myths and build a smarter, cleaner grid. ⚡🌍

Conclusion
The energy transition demands a rethink of old paradigms. Baseload power served its purpose in a bygone era, but today, it risks holding us back. Let’s retire the myth and embrace the tools that make our energy systems cleaner, smarter, and more resilient.
We don’t need more baseload—we need better power.
