Well, here we go again. The 'Conservatives' either oblivious to what the technology is doing, or just plain lying to protect their ideology concerning coal and oil.
Tesla now has grid scale batteries for sale at $250 per kw/hr, in 500 kw/hr to 10 mw/hr packages. Eos has $160 kw/hr for large orders, $200 kw/hr for smaller ones.
Eos Energy Storage introduces grid-scale battery system at $160/kWh
22 January 2015
Eos Energy Storage announced the commercial availability of its MW-scale Aurora system for deliveries starting in 2016. Eos’s standard Aurora 1000|4000 product, a containerized 1 MW DC battery system providing four continuous hours of discharge, offers a cost-effective energy storage solution competitive with gas peaking generation and utility distribution infrastructure. The Aurora 1000|4000 will be sold at a price of $160/kWh in volume.
The Aurora product employs Eos’s patented Znyth battery technology that uses a safe aqueous electrolyte and a novel zinc-hybrid cathode to enable extremely low-cost electricity storage and long life. Eos’s grid-scale product is designed to reliably integrate renewable energy, improve grid efficiency and resiliency, and reduce costs for utilities and consumers

As expected, Musk also announced a second battery product for the grid – the PowerPack. While there appears to be little detail yet compared to the PowerWall, Musk confirmed that the PowerPack will be a 100 kWh battery that can be stacked to scale up to a gigawatt-class system. Musk said these utility and industrial-scale batteries cost $250 per kilowatt-hour — meaning the 100 kWh PowerPack is ostensibly priced at $25,000.

How Can Batteries Enhance the Power Grid?
Power demand in Texas is uneven. Because most Texans power down when they go to sleep at night, demand drops considerably, and power plants can sit idle. During the day, demand increases so greatly that its potential to outstrip capacity–resulting in the occasional power outage–is an ongoing threat. Power generation is uneven, as well, as Texas gets a growing amount of its energy from alternative sources, like solar and wind power. It’s clean and green, but unfortunately these sources can be intermittent. Sometimes the sun shines and the wind blows, and sometimes, not so much.
With their ability to store a surplus of energy and then feed it back into the grid when necessary, utility-scale batteries can solve the problems of both intermittent supply and cyclical demand. Power plants can operate on a more smoothed-out schedule of 24 hours, instead of cranking frantically in the daytime and foundering listlessly at night. Solar arrays and wind farms, such as
Duke Power’s Notrees wind farm, with its 36-megawatt battery facility, can store power generated at peak weather to help ease demand on the grid even in non-ideal conditions, such as those hot summer days with nary a breeze to alleviate a jump in air-conditioning use.
One of the main supporting factors behind Oncor’s push to get batteries into the grid is that the cost for the batteries is forecast to be lower by 2018 than previously projected. Electric car manufacturer Tesla, with whom Oncor is in talks, will be producing industrial-sized batteries at its new “
Gigafactory” battery production facility in Nebraska, scheduled to open in 2017. A study conducted by The Brattle Group estimates that the lower outlay of costs, along with the ability to bring in revenue by renting storage space on the batteries and a reduction in power prices, would likely result in a savings for power customers of 34 cents per month off the average bill. Consumers would benefit both from a more consistent and reliable source of energy and a small reduction in their utility expenses.
Oncor is responsible for transmitting power to most North Texas including the Dallas and Fort Worth areas.

Obviously we can make wind and solar 24/7. And we can do it in a way that will cost the consumer less. In the meantime, you go ahead and chant, 'We can't do it, it is too hard'. The hell with you, we will do it because it is hard, and we are Americans. That is how we met the challenge to go to the moon.
