Despite hostilities that linger as a result of the 1986 nuclear nightmare at Chernobyl, Ukraine, and pressure from the European Union to shut down older-generation plants, Eastern European countries from the Baltic to Bulgaria are renovating existing nuclear plants or building new ones. If these projects become reality, the region will be able to secure its power supplies as well as cover the ongoing shortages in countries such as Greece, Macedonia, and Albania.

A confluence of circumstances promised to make 2008 a transformative year for renewable energy in the U.S. States enacted additional, and more demanding, renewable portfolio standards, promoting accelerated and sustained development of "green" energy resources. Increasing concerns about global warming and climate change prompted some of this activity. However, the unprecedented escalation of oil prices to almost $150 a barrel (translating into prices at the pump in excess of $4) was the largest impetus for demands that this nation end its addiction to fossil fuels.

Declining oil prices, supply issues, and dwindling financing may have battered solar energy in recent months, but the industry seems to have sparred well in the research arena. An assortment of institutions separately announced breakthroughs in their quests to boost the efficiency of solar cells. The technological advancements ranged in approach, from the development of an antireflective coating to the formulation of more efficient solar cell materials, but all point to promising possibilities for the industry.

Which new and emerging technologies will be essential to your power plant’s success? Our special cover story series gives you a glimpse into the future of advanced distributed controls, wireless applications, and automation technologies.

An energy-generating revolving door installed at Driebergen-Zeist railway station in the Netherlands is the latest experiment in eco-building. Dutch company Royal Boon Edam Group Holdings designed the manual door to match the newly refurbished station’s sustainable technology theme, while keeping in mind that the station — converted into a multifunctional area featuring restaurants and a tourist information and visitor center — holds 8,500 commuters at capacity.

The past decade has seen an explosion of technology that has significantly altered the process control industry. The adoption of commercially available technology driven by desktop computing has allowed suppliers to focus on applications to enhance the process and deliver ever-greater value to the user.

The Sri Lankan government in December commissioned the first phase of the 300-MW Kerawalapitiya Thermal Power Plant, the nation’s biggest combined-cycle power plant project. The $300 million plant in the western part of the country commenced operations by generating 200 MW (Figure 7). In its second phase, it will expand to 300 MW. Per government estimates, power produced by the plant is priced at about 20 rupees or $0.18/kWh.

Distributed control systems are powerful assets for new and modernized power plants. Thanks to three product generations of technology innovations, these systems now provide new benefits — including improved O&M efficiency, greater plant design flexibility, and improved process control and asset reliability — that help competitive plants advance in the game.

By now, most electric industry participants are aware of the mandatory reliability standards required by the Energy Policy Act of 2005 and managed by the North American Electric Reliability Corp. (NERC). Bulk-power system users, owners, and operators (known as NERC registered entities) are responsible for complying with the set of standards that are applicable to their operations in their specific region. Compliance is monitored by the NERC regions (Texas Regional Entity, Western Electric Coordinating Council, Reliability First Corp., Midwest Reliability Organization, SERC Reliability Corp., Florida Reliability Coordinating Council, Northeast Power Coordinating Council, and Southwest Power Pool) through spot checks, self-certifications, audits, and investigations.
