Full Title: Solar Plus Energy Storage: Comparing System Options Author(s): Chip Palombini Publisher(s): Dynapower Publication Date: 06/2017 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): North America currently has over 20 GW of installed utility-scale PV generation. With 2016 seeing the largest amount of PV installed to date with over 14 GW brought online. The majority of this installed utility-scale PV base could expand production hours and increase revenues with the addition of energy storage. Here we will examine the coupling of energy storage with PV by comparing three principle methods: AC-coupled, DC-coupled, and hybrid solar-plus-storage inverters. We will also consider all possible… [more]

Energy storage, a potential solution for integrating intermittent renewables and improving grid stability, again saw rapid growth this past year. A “transition year” for U.S. energy storage, 2016 saw a more diverse market emerge “both in terms of the types of systems (market segments) deployed and the business models.” These trends are expected to continue in the U.S. with combined residential, commercial, and industrial energy storage deployments predicted to surpass 2 GW by 2021. Despite this rapid growth, there are those who claim that the adoption of energy storage has been slowed by a “web” of regulations at all levels.… [more]

Full Title: Energy Storage and The Next Generation Utility: A Strategy Guide for the Future Author(s): PA Consulting Publication Date: 2016 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): Throughout the world, energy storage technologies are at a turning point. They are becoming more flexible, efficient and capable of reliably delivering energy to consumers, as needed. They are also playing a pivotal role in the growth of renewable energy and distributed energy resources. As technology costs decline and efficiency improves, we expect to see this market expand rapidly over a short period of time. For example, GTM Research expects the US Energy Storage annual… [more]

Do We Have The Raw Materials For The World To Become 80% Renewable By 2050?

There have been many voices lately saying that renewables could produce 80% or more of the world’s energy by 2050 in order to limit global warming to 2.5°C, as long as we develop sufficient energy storage and bring up efficiency and conservation. But the real issue is steel. It takes about 500 tons of steel and 1000 tons of concrete per MW of wind power. Even more to connect them to the grid. The United States has used 40 million tons of steel to build 48,800 wind turbines totaling 74,512 MW and costing about 150 billion dollars. Wind energy produces… [more]

Full Title: Renewable Electricity Generation and Storage Technologies Author(s): Publisher(s): Publication Date: Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): The United States has diverse and abundant renewable resources, including biomass, geothermal, hydropower, ocean, solar, and wind resources. These renewable resources are geographically constrained but widespread—most are distributed across all or most of the contiguous states. Within these broad resource types, a variety of commercially-available renewable electricity generation technologies have been deployed in the United States and other countries, including stand-alone biopower, co-fired biopower (in coal plants), hydrothermal geothermal, hydropower, distributed PV, utility-scale PV, CSP, onshore wind, and fixed-bottom offshore wind. Today, these… [more]

Full Title: Battery/Diesel Grid-Connected Microgrids: A Large-Scale, Industry-Based Case Study of Future Microgrid Capabilities Author(s): ABB Publisher(s): ABB Publication Date: 2015 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): As large scale battery technology and economies of scale continue to improve, many industrial utilities are investigating the use of battery technology as the basis for Grid Energy Storage Systems (GESS). Based in Victoria, Australia, AusNet Services, the state’s largest energy delivery service owning and operating approximately $11 billion of electricity and gas distribution assets that connect into more than 1.3 million Victorian homes and businesses, began investigating GESS in 2013. AusNet Services chose… [more]

The Energy Storage Promotion and Deployment Act of 2015, recently introduced by Sen. Marin Heinrich (D-NM) and Sen. Angus King (I-ME), seeks to create a National Energy Storage Standard. Similar to a Renewable Portfolio Standard, the storage standard would require electric utilities to meet a percentage of their generation via storage, in this case 1% of peak demand using any energy storage technology by 2021 and 2 percent by 2025. In real terms, utilities would have to add 8 GW of storage by 2021 and 18 GW by 2025. Available technologies range from electric and thermal salt batteries to pumped… [more]

The State And Promise Of Energy Storage

Energy storage has become one of the hottest topics in the electric power industry today as penetration levels of variable energy resources (e.g. wind, solar) rise rapidly. However, from the perspective of the electricity industry, analyzing energy storage can be dauntingly complex, and financial incentives are weakened by depressed electricity prices. A recent study summarizing the state of energy storage, “Energy Storage and Opportunities: A West Coast Perspective White Paper,” offers the following conclusions: Complexities in calculating and realizing the value of energy storage provides multiple system benefits that are often not fully valued, partly because of the complexity involved.… [more]

Last month, the National Alliance for Advanced Technology Batteries released “Distributed Energy Storage: Serving National Interests,” a white paper which outlines the benefits of distributed energy storage (DES) and its relationship to the nascent electric vehicle (EV) industry. According to the paper, DES systems can increase grid reliability, stability and security because of their “ability to provide… electric supply capacity and energy time shift, ancillary services, transmission and distribution (T&D) system support, electric utility customer energy cost management, and renewable energy integration.” These advantages may be necessary if the U.S. were to increase integration of renewable energy sources, see a… [more]

On March 13th, C2ES held a panel discussion in Washington, DC titled “Electric Vehicles Plugging into the U.S. Grid.” The panel addressed the opportunities and challenges surrounding broad roll-out of plug-in electric vehicles (PEVs). A key point of discussion was the need for harmonization between the auto industry, utilities, and government so as to optimize the electric grid as PEVs become a larger proportion of the vehicle fleet. Another key point was the need for consumers that are well-educated on PEVs. What’s keeping PEVs, and other alternative fuel cars, from breaking into the market? Is it simply a lack of… [more]
