Integrating large quantities of wind and solar energy is often considered a challenge due to the intermittent nature of renewable generation. I present evidence on the costs and benefits of renewable power based on data from the Iberian Electricity market, which as of 2012 produces over 20% of its electricity from wind power, and about 5% of its electricity with solar power. I examine the challenges of wind and solar integration from an empirical perspective, and quantify the relative impacts of uncertainty and volatility on realized electricity costs. I also show how market incentives can distort optimal planning, by examining wind farm behavior in centralized electricity auctions. Allowing wind farms to participate in centralized markets can increase competition and decrease procurement costs, but it might increase inefficiencies in the market.
Commercializing Wind, Photovoltaics, Lighting, and Batteries: The Impact of Government Policies During the Past 25 Years

On March 10th, Cathy Zoi will present the findings from Energy 158, a research seminar held during the Fall of 2013, that investigated the progress of wind, photovoltaics, lighting and batteries over the past 30 years, and the impact that government intervention had on this progress. She will then apply these lessons from history to propose a framework policy makers can use in the future.
Rationale for the research: Public policy imperatives have created a drive for energy technologies that can reduce greenhouse gas emissions, improve national security, and boost domestic economic activity. To accelerate the development and commercialization of these new technologies beyond what the market would deliver on its own, governments frequently use policies like direct R&D funding, financial incentives or penalties (e.g. through the tax code, state funds, or utility rates), mandatory targets or caps, information disclosure, and performance codes and standards to create market conditions that favor emerging technologies. There is significant public debate about the most effective mix of these policy interventions.

Grid flexibility is a characteristic that is proposed to help the integration of variable renewable energy resources. However it has proven very difficult to quantify and this has spurred intense research efforts over the past few years. There are many sources, sinks and enablers for flexibility in the grid and these are all subject to numerous research challenges. Flexibility will be introduced, defined and a number of methods to quantify it will be described. This will be followed by an overview of research into unlocking flexibility in the power system e.g. demand side participation and power system operational strategies. There are potential hidden costs of flexibility and some of these will be highlighted, for example thermal plant cycling, and mitigation measures to reduce these will be formulated. Concluding remarks will try to give insights into how a future grid with very high penetrations of variable renewable energy may look like.

The Renewable Electricity Futures Study is an initial investigation of the extent to which renewable energy supply can meet the electricity demands of the contiguous United States over the next several decades. This study explores the implications and challenges of very high renewable electricity generation levels--from 30% up to 90%, focusing on 80%, of all U.S. electricity generation from renewable technologies--in 2050.
At such high levels of renewable electricity penetration, the unique characteristics of some renewable resources, specifically geographical distribution and variability and uncertainty in output, pose challenges to the operability of the nation's electric system. The study focuses on key technical implications of this environment from a national perspective, exploring whether the U.S. power system can supply electricity to meet customer demand on an hourly basis with high levels of renewable electricity, including variable wind and solar generation. The study also identifies some of the potential economic, environmental, and social implications of deploying and integrating high levels of renewable electricity in the United States.

For the first time in history, the human demand for a number of critical natural resources is approaching or exceeding the global supply of these resources. Sustainable development requires that the demand for resources be brought into, and maintained within, the limit of supply. This means that the only possible growth paradigm for society demands that we use our natural resources much more efficiently and, when possible, develop alternatives for resources where demand approaches supply. While this paradigm applies to a number of natural resources, it is most obviously playing out with respect to energy. Here, two resources are challenged by demand at the global level: fossil fuels (especially oil) and our common atmospheric garbage dump for greenhouse gas waste.
This is leading a number of countries – especially those where energy security in the short-term is potentially threatened – to invest in or plan alternative energy systems. Denmark has set an absolute date of 2050 for removing fossil fuels from its energy system, the first country in the world to take such action. This talk will describe the Danish plan, how it was developed, the strategy for achieving fossil fuel independence and the status of the transition.

The last several years have seen a flurry of activity in industry and academia in the Smart Grid space. The need for a smarter electrical grid in North America stems from emerging challenges in congestion, reliability, safety and renewable energy integration, that may be more cost effectively resolved with advanced controls technology than with bulk infrastructure growth. Solutions to these problems require system thinking; many technologies need to work together to collectively provide relief. It is important to note that the problems change dramatically as you migrate to different parts of the world, with every region having unique challenges and opportunities. This talk will focus on Smart Grid technologies for mature grids such as the one in North America, and will pay special attention to the integration of renewable energy resources. A brief discussion of the grid in India will be provided for contrast.

What happens when you put lots of wind and solar power onto the power system? Do you need more storage? Do you need more reserves? When does the system 'break'? What actions can be taken to integrate wind and solar power into the power system without large cost increases to consumers?
Wind and solar power are inherently variable and uncertain. This causes difficulties for power system operators who must maintain reliability. Over the past several years, utilities and researchers have simulated power system operation with various penetration levels of renewable energy, examining increased costs due to integration of the renewables and mitigation measures to more cost-effectively accommodating the renewables. Debbie will present an overview of recent renewable energy integration studies in the US and Europe. She will focus on the recently released Western Wind and Solar Integration Study, one of the largest wind and solar integration studies to date, that examines the integration of up to 35% wind and solar energy into the power system. Issues addressed include: utility cooperation, tradeoffs between local and remote renewable energy resources, geographic diversity, storage, reserves, and improved forecasting.
