Rosarito's air cleared, and the plant even had excess power to sell into the California grid.
The energy storage system will produce hydrogen using excess power generated from renewable energy, primarily wind power.
After subtracting the draw of running lights, headlight, cooling fan, among other components, the excess power is available to run add-ons including lights.
If the wind intensifies very quickly, the amount of power generated by the wind turbines increases rapidly, injecting excess power into the generation system.
At night, as the apartments pull electricity from the grid, the use is intended to balance out the excess power produced during the day.

The pump storage hydro scheme is designed to "soak up" excess power generated by wind and wave farms, using it to pump water up to a reservoir.
Electric utilities love the idea, because they can sell electrons to "fill them up" at night, when they have excess power, and potentially draw the electricity out of them during the day when electrons are scarce.
With the existing wind capacity, there have already been times in recent years when surpluses have been generated and Denmark has actually paid other countries to take the excess power supply (much like the situation in West Texas, where surpluses of wind occasionally result in negative pricing for short periods).

It took all the region's wind turbines offline for about five hours and it expects to continue to pull the plug on them for a few hours almost every night until well into July, when enough snow in the Cascades and northern Rockies will have melted for the excess run-off (and therefore the excess power) to subside.
Rather than letting the heat escape, a cogeneration plant uses the excess energy to power a heating and cooling system.
But companies like these have an excess of commercial power in their particular supply chain that shifts business risks, like the non-availability of goods on a production line, to a supplier without shifting the associated profit.
By 2014, this rural district will be providing 236% of its own energy needs from renewables and hopes to generate significant revenue by exporting excess carbon-free power to the open market.
When excess wind energy is generated, power is often transmitted to these neighboring countries.

Consumers and businesses who have solar panels on their rooftops might want batteries to provide backup power or to sell excess electricity to utilities.
The current attack on cartels comes at a time when the temptation to strike cosy deals with competitors is stronger than ever, as pricing power remains weak and excess capacity abounds in the wake of the global economic slowdown.
Proponents of a hydrogen economy want to produce the hydrogen with excess electricity from renewables such as wind power and solar energy.
That way grid operators could, say, automatically lower the cost of transmitting power from a region with excess to capacity to one with a shortage, instead of letting the problem fester until the peaker plants turn on and phone calls and faxes fly.
The power density of processor chips used in PCs today is on a par with that inside a nuclear reactor--and anyone who's ever perched a notebook computer on his lap for a prolonged period knows all that power often manifests itself in excess heat.
That is a massive amount of excess overhead in hardware, real estate, power consumption and productivity.

Farmers, factories and power stations that deal with a lot of excess biomass could be a few of the beneficiaries.
FORBES: Orange Peels Could Be Made Into Biodegradable Plastic
The basic premise of these bank disintermediaries is that they harness the networking power of the Web to match people who have excess cash with people in need of it or those who simply want to refinance credit card debt.
Of course, new gas fired power plants will initially be built in regions with less excess capacity (post coal plant retirement).
Even as energy prices rose and nuclear power plant capacity was boosted in the late 1990s and early 2000s, excess inventory and uranium from decommissioned Russian warheads kept prices low.
My colleague William Pentland writes about another consequence of excess hydropower: wind farms in the Pacific Northwest are being forced to disconnect from the power grid out of concern their added electrons with overload the system.
