  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • Avoiding the Power Grid with Renewable Energy

    For approximately one hundred years, thriving countries have been dependent on only one form of distributing power; electricity sent over large transmission grids from plants generating electricity, to customers in businesses, homes, and factories.  Generators extract energy from rooftop solar panels, garbage, and sewage, which replace or assist coal, nuclear, and natural gas plants. A ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • Case study - Procurement and installation of a Biogas desulphurization unit at the Chania WWTP

    A proposal based on Bioconservacion’s technology was selected as the winning bid in the public tender released in 2015, covering the design, procurement and construction of a biogas desulfurizing unit to be installed in the waste water treatment plant in Chania, Greece. With a population over 100,000, Chania is the second largest municipality in the Greek island of Crete. Its waste water ...

  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Knowing power grids and understanding complexity science

    Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man–made systems like power grids, gas and water networks and the internet, have been also included in this network framework, albeit sometimes ignoring the huge historical body of knowledge surrounding them. Although ...

  • Ocean Power connects wave energy system to grid

    Ocean Power Technologies, Inc. (Pennington, NJ) announced that it has achieved what it claims to be the first-ever connection of a wave-energy system to the power grid in the United States. Ocean Power’s PB40 Powerbuoy system is now delivering power to the grid at the U.S. Marine Corps Base Hawaii on the island of Oahu. The Powerbuoy unit, which was installed in December 2009 at a ...

  • `Sahara Power` needs pan-European grid operator

    A consortium of leading European – mostly German – companies plans to invest €400 billion in a megaproject to generate solar power in the Sahara desert. “Desertec”, as the project is called, could cover 15 percent of European electricity demand. The problem is, how do you transport this power to Paris and Berlin? ‘It will not work without a pan-European grid operator.’ The figures for the ...

  • Smart Grid needs a Facebook

    We think we know how smart grid technology will change the utility industry. But do we really? Take a look at this documentary made in 1969. It’s a view of how the world perceived the coming Internet (It’s also a pretty amusing look at how sexist our society still was at that point.)  ...

  • Smarter grids, appliances, and consumers

    More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas ...

  • Wanted: GOLD for smart grid

    As John McDonald tells it, smart grid needs GOLD. And he’s not talking money. GOLD stands for Graduates of the Last Decade, the technology savvy, risk-taking engineers and technicians who may be among the greatest benefactors of the new smart grid movement. While most recent college graduates face dismal employment prospects, for the GOLD kids, the job ...

  • The smart money is on smart grids

    In Asia, the utilities industry is growing at an incredible rate. Investments globally in the sector have lead to more available jobs, predicting the return to pre-recession levels of employment by Q1 2010. However, with such substantial growth comes opportunities which have to be managed correctly to sustain long-term development. With the world’s investors looking at Asia to see how such a ...


  • The Grid vs. Rooftop Solar

    The development of solar micro-grids and mini-grids in the remotest parts of Australia seems to be a rational step in the right direction economically. However, network operators all over the world are still in doubt when it comes to the vast population in urban areas adopting similar methods. The question lies with the homeowner choosing to buy the necessary power generating equipment ...

  • Grid integration of renewables in Egypt

    Integration of large Amounts of Renewable Electricity in the Egyptian Energy Grid - Capacity Building for Management and Engineer-Technical Level (Egypt-RE-Grid). The electricity sector of the Arab Republic of Egypt produces large amounts of electricity through thermal and hydroelectric power stations. Egypt has diminishing proven oil reserves and declining production. Natural gas production is ...

  • Smart Grid: The game

    In his best seller “Outliers,” Malcolm Gladwell shows that it is not equipment failure or storms that typically cause planes to crash, but wrong decision-making. Much the same can be said for the power grid crash that took down a large swath of the Northeast in August 2003. The emerging smart grid is supposed to make our power system more reliable. The bad news is that it also will add complexity ...
