Regional policies can decide wind’s future

ElenaThis article was first published in WindPower Monthly, March 2014.

Australian wind energy has been on a roll for much of the time since the introduction of the Renewable Energy Target (RET) in 2001. Installed capacity currently stands at more than 3GW, up from just 200MW a decade ago. Behind this success are a world-class wind resource and a well developed supply chain. Investment in wind will account for the lion’s share of the A$18.7 billion (US$ 16.3 billion) expected to be generated by the RET.

But despite strong historical performance, political wrangling over federally-legislated RET has made investors wary and the future of wind energy in Australia is uncertain.

Some comfort has been provided by the federally-funded Clean Energy Finance Corporation (CEFC) and Australian Renewable Energy Agency (Arena). although the respite may be shortlived. Arena is facing cuts to its funding and the CEFC is at risk of being dismantled under the new conservative coalition government that took power in September. …READ MORE

Where is the energy storage market heading and where is the disruptive change? (Part 1)

Drivers of future storage markets
Before the dawn of the 20th century, burning wood was the main source of energy. The 20th century witnessed three major fuel transitions from wood to coal, to oil, to gas. The past century also brought us hydro and nuclear power. The use of these fuel sources is not expected to grow in the 21st century; and in fact, some of them, like coal, are expected to become an insignificant part of our energy portfolio. As shown in Figure 1, the flourishing fuels of the 21st century are renewables particularly solar energy that is the most accessible form at the consumer level.

Preparing to meet NERC TPL-001-4? Customer analytics can help

GIFFORDOne of the most intriguing aspects of electric utility customer analytics is the diversity of applications to which they can be applied. Common applications include load research for cost allocation and rate design support, the planning and evaluation of energy efficiency and demand response programs, load forecasting for system planning, and, increasingly, in broader distributed energy resource applications and grid management (e.g., conservation voltage regulation).

Voltage stability modeling is one application that may not be top of mind. In 2013, we kicked off a project sponsored by the U.S. Department of Energy to develop a framework for dynamically representing system load in New England. This work was motivated by NERC standard TPL-001-4 Requirement R2.4, which is to go into effect Jan. 1, 2016. The standard specifies that system peak and off-peak load representations, including the behavior of induction motors and other load components, be developed and updated once in five years for use in annual stability analysis assessments. …READ MORE
