On Sept. 9 the parties announced they had agreed on a 20 - year power purchase agreement under which KIUC will pay SolarCity 14.5 cents / kWh for power needed meet
its evening peak load.
Molten - salt energy storage will be used to store energy for a few hours in order to generate power during
the evening peak load.

Concentrated Solar Power (CSP) can be a night - only dispatchable (D - CSP) plant; with its entire solar energy absorbed by day to be delivered after dark to cover
the evening peak load on the grid, according to a study funded by the US Department of Energy (DOE).

Not exact matches
A Powerpack system enables StubHub to store electricity during off -
peak times, when the grid is more capable and favors delivering excess electricity, then discharge to the stadium during
peak evening hours when the grid is under its heaviest
load.
The Arizona project was called out due to its
load shifting nature — allowing for solar power to be used during the early
evening peak demand period.
One of the main objectives of the project is to
even out the
peak load across a neighbourhood, and most of the technology needed to achieve this is already available.
Comparing squat variations, Russell and Phillips (1989) reported that
peak hip extensor moments were greater during the back squat than in the front squat,
even when each variation was performed to a standardized depth and with the same relative
load.
In the snatch lift as performed in competition,
peak vertical bar velocity can reach 2.1 m / s (Garhammer, 1985; Okada et al. 2011) and the second pull is the fastest phase of the lift (Campos et al. 2006; Harbili, 2012; Korkmaz & Harbili, 2012; Akkuş, 2012; Harbili & Alptekin, 2014; Harbili, 2015), although
peak vertical bar velocity is
even higher with sub-maximal
loads (Hadi et al. 2012).
Wretenberg et al. (1996) found that
peak knee extensor moments were lower during powerlifting squats than during Olympic weightlifting - style squats,
even though the powerlifting squats involved the use of greater absolute
loads; Swinton et al. (2012) reported that
peak knee extensor moments were greater in the box squat variation than in either the traditional or powerlifting squat variations, but there was no difference between traditional and powerlifting squats.
However, increases in muscle fascicle length are also likely dependent on the mechanical
load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise,
even when muscle length at
peak contraction is shorter (Bourne et al. 2016).
Free weights and other constant
loads (
even those involving machines) during most common exercises produce a
peak contraction at long muscle lengths (there are some exceptions).
They just put 377 megawatts of solar on grid at Ivanpah, which needs more than 8 hours of backup PLUS more for
peaking morning and
evening loads.
«An aggregated fleet of vehicles or chargers can act as a [demand response] resource, shifting
load in response to price signals or operational needs; for example, vehicle charging could be shifted to the middle of the day to absorb high levels of solar generation and shifted away from
evening hours when solar generation disappears and system net
load peaks.»
What's especially unfortunate is that the sun tends to go down just before the
evening peak of demand, which means net
load goes from very low to very high, very quickly (13,000 MW in three hours, in the CAISO example), and then down low again.
The sun isn't
even shining on the north / east side of the house during the time of
peak load, yet manual J accounts for it.
Capable of executing up to 2.5 million transactions per second, the system will be able to operate at full capacity
even during the
peak load times.
