PJM Grid Operators: We Can Handle 30 Percent Renewable Energy Integration, And Here's How

Mon, 03/10/2014 - 10:00

Experts believe that the PJM Interconnection system, which encompasses all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia, can handle up to 30 percent of its energy from wind and solar without "any significant reliability issues," assuming transmission upgrades and additional regulation reserves — and at the same time reducing costs and reliance on its costlier conventional generation fleet.

Canadian Solar, Chaori Cast Cloud On Solar Shares

Mon, 03/10/2014 - 09:06

After a massive rally over the last year, shares of solar panel makers could be set for a few months of winter following a disappointing earnings announcement from superstar Canadian Solar (Nasdaq: CSIQ) and a debt default from second-tier player Chaori Solar (Shenzhen: 002506). Such a correction was almost inevitable after last year’s huge rally a

Mapping the World One Small Hydropower Plant at a Time

Mon, 03/10/2014 - 08:11

The United Nations Industrial Development Organization (UNIDO) and the International Centre on Small Hydro Power (ICSHP) announced last month that they have launched a new web-based knowledge-sharing portal on small hydropower. The purpose of the portal is to hopefully make it easier for developers, policymakers and other interested stakeholders to access data about the vast potential of small hydropower.

Google Reaps Tax Breaks in $1.4 Billion Renewable Energy Bet

Mon, 03/10/2014 - 06:55

On a Northern California farm where silage for animal feed once grew, Google Inc. is generating power from more than 100,000 solar panels to heat nearby homes — and double down on an area of energy many investors shun.

Predicting PV Plant Power Fluctuations and Optimising Energy Storage

Mon, 03/10/2014 - 06:53

The ability to accurately predict and prevent power fluctuations is of considerable importance to Solar PV (photovoltaic) plant operators in terms of sustaining profitability, estimating revenue returns and ensuring customer quality of service. Variations in solar irradiance can cause rapid fluctuations in power generation, reducing the quality and reliability of the power generated by large grid-connected PV plants.

Energy Efficiency Ain't Got No Respect

Mon, 03/10/2014 - 06:08

While politicians and planners focus on energy generation and fuels, it is energy efficiency that should be the first winner. As I tell my students as well as members of Congress — it is ALWAYS less expensive to save energy than generate any type of energy.

India Suspends Wind Forecasting Fines Due to Data Inaccuracy

Mon, 03/10/2014 - 05:41

An Indian rule requiring wind farms to predict output or face fines has been temporarily suspended as the regulator reconsiders the best way to ensure stability of the grid, which suffered the world’s biggest outage in 2012.

Transmission Tweak Promises Big Cost Benefits for Offshore Wind

Fri, 03/07/2014 - 11:37

Offshore wind development is being pushed further out into deeper waters, emphasizing longer, higher-capacity transmission systems. Most newer offshore wind farms from Europe to the U.S. are looking at hundreds of kilometers of transmission lines: the U.K. Crown Estate's Round 3 allocations, interconnection systems from Germany's North Sea to the U.K.'s National Grid Western Link, and the proposed Atlantic Wind Connector in the U.S. Mid-Atlantic.

Liquid Metal Batteries May Be the Answer for Cheap Energy Storage

Fri, 03/07/2014 - 10:59

A 40-foot trailer loaded with 25 tons of liquid metals may be the solution to the renewable energy industry’s biggest challenge: making sure electricity is available whenever it’s needed.

Defining an Industry: Solar PV Operations & Maintenance versus Asset Management

Fri, 03/07/2014 - 09:16

There are more solar photovoltaic (PV) systems in the U.S. than ever before and more of them are aging out of warranty coverage. The need to manage this portfolio of residential, commercial and utility-scale solar assets is accelerating a relatively new industry sector, solar PV operations and maintenance (O&M).

Hawaii Senator Blasts Agencies for Geothermal Project Standstill

Fri, 03/07/2014 - 08:14

Attorneys and a state Senator are getting involved in a still-unawarded geothermal contract Hawaii Electric Light Co. (HELCO) had originally said would be awarded before the end of 2013. The RFP was posted in early 2013 and asked for a 50-MW influx of geothermal power development on the Big Island of Hawaii. Disruptions caused by the continuing delay include losses of the companies that submitted proposals, and a breach of public trust lawsuit has been brought against the State of Hawaii; Governor Neil Abercrombie; the Public Utilities Commission (PUC); Department of Commerce and Consumer Affairs; Department of Business, Economic Development, and Tourism; Hawaiian Electric Company (HECO); Maui Electric Company; Hawaii Electric Light Company (HELCO); and Hawaiian Electric Industries (HEI).

Ten Clean Energy Stocks for 2014: March Update

Fri, 03/07/2014 - 08:06

After a rough January, the stock market recovered in February, while clean energy stocks partied like it was 2013.

Can Solar Power Help Marijuana Growers?

Fri, 03/07/2014 - 08:00

The sun has been around for a long time. So has marijuana. Legal pot in the U.S. hasn’t been around for a long time. In fact, earlier this year Colorado became the first state to sell legal marijuana in the U.S. With the country’s—if not the world’s—eyes on Colorado’s new policy, growers are looking for opportunities to better use their profits whi

Navigating the Winding Road of Geothermal Project Financing, Part I

Fri, 03/07/2014 - 06:35

It is no secret that renewable energy project development cycles present many unique challenges — as well as promising opportunities — for developers, investors and power users alike. Geothermal energy project development in particular can be a challenging endeavor, based on the extended timelines involved in successfully proving a resource, mitigating drilling risk and managing the subsurface reservoir on an ongoing basis. These are unique “geo sector-specific” issues that must be managed, in addition to the typical power plant development and construction issues inherent in any energy project endeavor. Due to these challenges, the corresponding financing of geothermal projects must be carefully tailored to match these specific features.
