The UK Conservative and La, using the foghorn of the government-subsidized/controlled Corporate Media, brainwashed the people to vote for them for decades.

Those voters ended up having the highest electric bills, i.e., total bill divided by consumed electricity, c/kWh, while the elite Owners are laughing all the way to the bank.

.

Any energy systems analyst would know Spain/Portugal-like blackout problems would eventually happen, before a single W/S system were connected to the grid, but naive, woke, technically illiterate enviros do not want to listen to the pros. All wind/solar/battery nonsense must be stopped dead by taking away the generous subsidies.

.

The More W/S Electricity on the Grid, the Less the CO2 Reduction/kWh, due to Inefficiencies

Analysis of 2013 data of the island Irish grid showed the CCGT fleet operating at about 50% without wind; at 45.58%, with 17% wind.
At higher W%, the CCGT fleet operates at lesser efficiencies (high Btu/kWh, high CO2/kWh), until no CO2 is reduced.
Fortunately, Brussels paid for major connections to the much larger UK and French grids.

As a result, most of the ups and downs of wind output disappeared in the noise of the large grids.

Expensive Wind/Solar Systems

The over-taxed, over-regulated taxpayers and ratepayers are paying at very high rates, c/kWh, for: 1) electricity, and 2) Heat Pump heating/cooling, and 3) EV driving.

There is no way such high-cost electricity would increase standards of living and increase the GDP.

Businesses and skilled people would move to low-energy-cost states.

These businesses and people are tired of paying for:

.

1) Highly subsidized, expensive W/S systems that disturb the grid with weather-dependent, variable, intermittent electricity, which has caused expensive brownouts/blackouts, as in Spain/Portugal, California, Texas, New England, etc., and many other places, over the years.

2) Grid expansion to connect all these far-flung wind/solar systems to the grid,

3) Grid reinforcements to ensure the grids do not crash during periods with higher levels of W/S power

. 

Here are some operational realities of W/S systems that are at the core of their problems:

.

Synchronous Rotational Inertia, SRI, Stabilizes the Grid

Closing down traditional plants (nuclear, gas, coal, hydro), with rotating generators that provide SRI, de-stabilizes the grid; a death sentence for the grid.

.

Wind/solar systems provide ZERO SRI to help stabilize the grid, because their variable outputs are digitized, then reconstituted into an artificial sine wave with the same phase and frequency as the grid.

Super expensive battery systems provide ZERO SRI.

Battery systems can provide virtual inertia, at very high c/kWh, by means of their back-end DC to AC power electronics (which failed in Spain/Portugal), which can quickly counteract voltage/frequency drops for a short time.

.

Connections Between Grids

Almost all grids have connections to other grids for import and export purposes.

About 50% of such connections are high-voltage, direct-current lines, HVDC

Such DC connections transfer power, but transfer ZERO SRI to other grids.

.

Reactive Power

No AC grid can function without positive reactive power; say power factor of 0.8

Wind/solar systems draw reactive power FROM the grid; say power factor of -0.8

All traditional power plants are automatically set up to feed positive reactive power TO the grid.

.

Synchronous Condenser Systems

The weather-dependent, variable/intermittent, wind/solar feed-ins to the grid often create transmission faults.

Those faults are often minimized with synchronous-condenser systems that provide positive reactive power TO the grid.

Blackouts 

In case of too much W/S power, it needs to be curtailed.

Owners usually get paid for what they could have produced.

.

In case of too little W/S power or a W/S outage, reliable, quick-reacting CCGT plants, in Standard Operating Procedure, SOP, mode, would:
.
1) Provide a few seconds of SRI "ride-through" to give switches time to switch, and
2) Provide power to the grid, within seconds, to counteract voltage/frequency drops, 24/7/365

3) Enable automatic load shedding to take place, as needed, etc.

.

NOTE: If battery systems were used, they would be empty after a few hours, with no prospect of a black grid to refill them.
.
NOTE: Spain/Portugal would have needed about 10,000 MW of CCGT plants in SOP mode to avoid its recent blackout.
As a fleet, they would operate at up to 75% output throughout the year, and quickly provide up to 2500 MW, in case of a W/S outage.

Black Start Procedure for a 100 MW CCGT Power Plant

.
Initial Power Source: The on-site auxiliary generator is started. It provides power to critical plant systems, including control, safety, and communication systems. 
Plant Startup: The auxiliary generator then powers the CCGT plant's essential systems. This includes cooling systems, fuel handling systems, and starting the gas turbine.
Connecting to the Grid: After the CCGT plant is spinning at 3600 rpm at the same phase and frequency as the grid, it can be connected to the grid to supply power to its section of the grid. That section powers another power plant, etc., until all sections are up and running. Only then, grid-destabilizing W/S systems are connected.
