Panelists debating the pros and cons of a regionalized western power grid seemed to agree that the development of such a system is inevitable, but they disagreed on how fast the evolution should occur.

The panel discussion took place during the California Independent System Operator (ISO) Stakeholder Symposium held on September 7 in Sacramento. At one point, the moderator of the session, John Danner, senior fellow at the University of California, Berkley, Hass School of Business, suggested that the dialogue had progressed beyond the question of whether or why a regional approach might be beneficial, to a debate about how and when it should be implemented (Figure 1).

“It’s certainly true that the physics suggest operating a bigger grid is better,” said Marc Joseph, attorney with Adams, Broadwell, Joseph, and Cardozo, “but .…

A merger proposed between Canadian firm Enbridge and Houston-based Spectra Energy Corp. could create the largest energy infrastructure company in North America.

The companies announced on September 6 that they have entered into a definitive agreement to combine in a stock-for-stock merger transaction that has an enterprise value of $ 127 billion. The transaction was reportedly approved by both companies’ boards of directors and could close in the first quarter of 2017, if shareholders and regulators approve it.

If completed, Enbridge shareholders would hold 57% and Spectra shareholders would own 43% of the combined company, which is to be called “Enbridge Inc.” It would be headquartered in Calgary, Alberta, though Houston would remain the company’s gas pipelines business unit center.

The merger would bring together the companies’ myriad energy infrastructure assets in North America, including liquids and gas pipelines, U.S. and Canadian midstream businesses, a regulated utility portfolio, and several renewable projects.

“Enbridge has been assessing opportunities to extend and diversify our sources of growth,” Enbridge President and CEO Al Monaco told investors in a webcast on Sept.…

Duke Energy Renewables, part of Duke Energy’s Commercial Portfolio, announced on September 7 that it will add six Georgia solar projects to the 2.8-GW renewable energy portfolio the company owns and operates.

The projects are relatively small in terms of capacity—averaging about 1 MW DC each (769 kW AC)—but they are the first Duke Energy has acquired in Georgia, giving it projects in 14 states (Figure 1). SolAmerica Energy developed the sites, located in the southern and central part of the state, under an engineering, procurement, and construction agreement with REC Solar, a Duke Energy affiliate.

“In acquiring these solar sites, we add Georgia to our growing U.S. renewables footprint,” said Rob Caldwell, president, Duke Energy Renewables and Distributed Energy Technology. “SolAmerica and REC Solar have completed quality projects that will deliver clean energy to Georgia Power’s customers for years to come.”

The projects—constructed with panels manufactured by Yingli—are part of the Georgia Power Advanced Solar Initiative.…

Lloyd’s Register on Current Nuclear Power Challenges

POWER Editor Gail Reitenbach interviewed King Lee of Lloyd’s Register on June 29 at the World Nuclear Exhibition in Le Bourget, France. The firm is a “non-profit distributing charity with a public benefit mandate,” which means that it is independent from shareholders, and profits are distributed to a variety of educational and other charities. Its nuclear group has provided independent, expert technical advice on safety and risk management for more than 60 years, beginning with the UK’s Calder Hall reactors in the 1950s. The UK vote to exit the European Union (EU), known as “Brexit,” had taken place the previous week. Questions and answers have been edited for length and style.

GR: What effect do you think Brexit, if it actually goes through, will have on UK nuclear plans and the European power sector generally?

KL: I think it’s too early to say whether Brexit will happen, and if it does happen, what form it will take, because the details will have to be worked out between the UK and EU countries.…

An Asian Nuclear Duo: Monju Down, Bataan Up?

With costs for a restart escalating, Japan is considering scrapping its troubled Monju fast breeder nuclear reactor, just as a never-started nuclear plant in the Philippines may get a new lease on life.

Monju May Be Finished

Japan Times reported that readying the Monju plant for restart “would cost several hundred billion yen.” Sources said that “a political decision” on decommissioning is likely. The science ministry has been looking for someone to run the 280-MW facility (Figure 1) but has found no takers.

Japan’s Nuclear Regulatory Authority (NRA) last year ordered the ministry to come up with a new operator because of the plant’s poor performance. Construction began in 1986, and the plant first went critical in 1994. But a nasty fire caused by a leak of sodium coolant in December 1995 shut the plant down and led to a scandal as the semi-governmental operator at the time tried to cover up the accident.…
