  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

  • As renewable electricity is added to the grid, are power markets misfiring?

    When increasing megawatt-hours of variable solar and wind energy began coursing through the grid, the initial concern was an operational one—could grid reliability be maintained. But it turns out those megawatt-hours are creating market challenges, as well. What needs to be done to right the markets? Travis Kavulla, vice chairman of the Montana Public Service Commission, and Albert Cheung, ...

  • North of Scotland shines for Moray ‘super-solar’ site

    A massive solar project in Moray which could provide enough electricity to power the whole of Elgin demonstrates that the north of Scotland is a prime location for this type of renewable energy solution. The ambitious energy project will use around 200,000 solar PV panels and will provide enough electricity for 21,000 homes. It is being planned by Elgin Energy at the former RAF airfield at ...

  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

  • The three S approach to uncertainty

    Life seems to be getting more and more uncertain. We are being warned about a Brexit rollercoaster and the oil price, at least in percentage terms, seems to be doing a good impersonation of an elevator; up one minute, down the next. All this uncertainty makes decision-making complex , especially when they concern long-life assets. Against this background I have been thinking about the question of ...

  • Marine AC UPS for Critical Offshore Installations

    Equipment installed in ships or offshore installations typically operate under tough conditions, and any possible equipment failures can have serious cost impact. Despite this, products not really suited for the applications are often chosen based on the initial cost rather than looking at the total cost of ownership. One example is the use of a modular marine AC UPS versus the use of a modified ...
