297 The Electricity Pricing Episode
Term

CPOs

CPOs are the companies that run public EV charging stations. They buy electricity and then sell it to drivers at the charger.

Concept

wholesale price

Wholesale price is the price of electricity at the “bulk” market level. Retail prices (what you pay at home) are built on top of that.

Concept

marginal cost of wind and solar vs gas or coal

They’re comparing power sources: wind/solar don’t need fuel, while gas/coal do. Fuel-burning plants tend to make electricity more expensive when they’re used.

Concept

zero marginal cost

Zero marginal cost means the “extra cost” to make one more unit of electricity is very low. Wind and solar don’t burn fuel, so their per-unit cost can stay lower than fuel-burning power plants.

Term

grid

The “grid” is the big electricity network that delivers power from where it’s made to where people use it. It has to keep supply and demand matched so the lights don’t flicker or go out.

Term

demand forecast

A demand forecast is a prediction of how much electricity people will use at certain times. Utilities use it to decide how much power to generate so they don’t run short.

Term

peak

A “peak” is when electricity use is at its highest. During those times, the grid may need to use more costly power sources to keep up.

Term

megawatt hours

A megawatt-hour (MWh) measures how much energy is used or produced. Think of it like “power for a certain amount of time,” such as running 1 megawatt for one hour.

Term

kilowatt hour

A kilowatt-hour (kWh) is the unit most electricity bills use. It’s how much energy you use when you run 1 kilowatt of power for one hour.

Term

interconnections

Interconnections are cables/links that connect one electricity network to another. They let countries share power to help keep the grid balanced.

Concept

wholesale electricity market

This is the market where electricity is bought and sold in bulk before it gets to your home or business. The price there can influence what you pay.

Term

marginal pricing

It’s a pricing rule where the electricity price is set by the “last and most expensive” power plant needed to keep the lights on. That means cheap energy can still end up priced high if some costly energy is required.

Term

strike price

The strike price is the agreed electricity price in advance. Under a contract for difference, the real market price is compared to this number to decide whether money is paid in or paid back.

Term

contract for difference

A contract for difference is like a price guarantee for renewable energy. If electricity sells for more than the agreed price, the generator gives the extra back; if it sells for less, they get help to reach the agreed price.

Toyota A90

The Toyota Supra is a sports car made by Toyota. It’s designed to feel fast and fun to drive, with a focus on performance. In this podcast, it’s brought up in the middle of a discussion that’s mostly about electricity and heating costs.

Term

renewables obligation

This is a government-style add-on that helps pay for building renewable power, such as wind farms. It shows up as an extra line item on your electricity bill.

Term

CFD

A CFD is a contract that helps protect certain power projects from price swings. If electricity prices are too low, the contract makes up the gap so the project still gets paid.

Term

capacity market

A capacity market is like paying power plants for standing by and being ready. The goal is to prevent shortages when demand is high or renewable output is low.

Term

VAT

VAT is a tax added to purchases. It can make your electricity bill higher even if the underlying electricity cost is relatively low.

Term

cost to serve

Cost to serve is what the electricity company spends to manage your account and deliver the service. It’s not the “power itself” cost, but it still gets added to your bill.

Term

Off Gem

Ofgem is the organization that regulates UK energy companies. Their reports can show how much money companies make and where costs come from.

Concept

curtailment and regeneration fees

Curtailment is when grid operators reduce or stop output from generators (often renewables) because the system can’t absorb all available power. Regeneration fees (as referenced here) are charges tied to grid balancing actions, which can add cost when the grid has to manage excess generation.

Concept

marginal cost pricing

Marginal cost pricing is when electricity price follows the cost of making the next bit of power. The problem is that the next bit might be expensive, so the whole price can jump even if cheaper sources are available.

Concept

levelized cost of ownership (LCO) for renewables vs fossil fuel generation

This is a “lifetime cost” comparison method. It estimates what it costs to build and run different types of power plants over many years, then averages it per unit of electricity.
