FAQs about The Challenge of the Last Few Percent: Quantifying the Costs and ... Coupon?

Is there a 'last few percent' of the 'balance challenge'?

"As far as the 'last few percent' of the path to 100%, there is no consensus on a clear cost-effective pathway to address both the Balance Challenge and the Inverter Challenge at the national scale. ...

Will Price declines help accelerating low-carbon energy deployment?

Although these dramatic price declines have been a boon for accelerating low-carbon energy deployment 6, further declines will be necessary to deploy renewables at the speed and scale that is needed to achieve climate targets, especially in the remaining parts of the world where fossil fuel power is still cheaper 7. ...

Does changing the 100% requirement affect system cost?

Third, changing the 100% definition—either via technology eligibility or the boundaries of the 100% requirement—can have as large an impact on system cost as other sensitivities such as battery costs or natural gas prices. ...

Are energy costs lower if a company has a firm capacity?

Results, published in another Joule article, show that costs are significantly lower if there is a cost-effective source of firm capacity—resources that can provide energy during periods of lower wind and solar generation, extremely high demand, and unplanned events like transmission line outages. ...

Why are renewables so expensive?

This isn’t a major problem for today’s electric grid, in which renewables make up only a small share of electricity. In fact, building and operating renewables can often be expensive because the costs of solar and wind have plummeted. ...

What is the balance challenge?

The Balance Challenge boils down to making sure the power system can economically balance supply and demand at a variety of timescales—from the critical seconds-to-minutes scale required to withstand unexpected outages, to the seasonal scale that matches scheduled power plant outages and maintenance with periods of lower demand. ...
