The country has just four weeks before severe power cutbacks will be needed.

Only extensive rain flowing into the South Island's hydro lakes will avert extensive cutbacks - but signs are that wintery weather headed that way will drop snow, not rain.

In developments yesterday:

* Civil Defence chiefs met in Auckland and urged the Government to implement an energy-savings campaign early.

* Meridian Energy warned that any "glitch" at Huntly's thermal power station this winter would plunge the country into an electricity crisis.

* Genesis Energy chief executive Murray Jackson said the North Island's peak demand - between 6pm and 8pm each day - had to drastically drop in the next four weeks.

Hydro-electric stations usually produce about 70 per cent of the country's electricity, but they are contributing only 50 per cent at the moment.

That has caused a shift in dependency to thermally generated power this winter, all of which comes from the North Island, Meridian spokesman Alan Seay said.

He said Meridian was still optimistic that winter power shortages could be avoided, with one warning: "If Huntly falls over, we've got an instant code red."

Huntly's coal- and gas-fired station has a 1450-megawatt capacity, making it the largest-capacity power station in the country.

The South Island's Waitaki and Clutha power schemes have a combined capacity of more than 2500MW, but their main storage lakes (Tekapo, Pukaki and Hawea) are at about half the level they should be.

Mr Jackson said users needed to conserve energy wherever possible to prolong what little reserves were left in the South Island's lakes.

Limiting use of clothes driers, dishwashers and washing machines would be a good step, he said. People should also look to reduce their lighting usage by half.

SPP update on power generation

Yesterday the "Making the Lakes Great" conference conclusions was posted on the H2O list by Dr. Gail Krantzberg, Director of the McMaster Univ. Dofasco Centre for Engineering and Public Policy, under the subject heading, "energy options to protect Great Lakes waters".
 
Here were the presentations, including the Canadian Nuclear Assoc., US Dept. of Energy, Suncor, Acelor Mittal, Hydro One.
 http://www.energy2100.ca/Presentations.html
 
check out the merged US-Canadian flags on slide 3 of
http://www.energy2100.ca/pdf/Energy2100_Scott%20Minos_U.S.%20Perspectives%20on%20Sustainable%20Energy.pdf
 
the rest of that slideshow is also instructive, eg. slides 21 and 22, and 55 (arms, and happy face nuke towers- seriously) !!!
 
or how about the rebranding of James Lovelock, author of "The Gaia Hypothesis" as nuclear advocate on slide 9 at:
http://www.energy2100.ca/pdf/Energy2100_Murray%20Elstons_Canada%92s%20Nuclear%20Industry%20-%20Preparing%20For%20The%20Future.pdf
 
And the conference conclusions, translated, mean a US-Canada integrated power grid, based on primarily carbon sequestered tar sands and coal sources, and nukes, with some wind, sun, and geothermal thrown in for PR. The dirty sources are to be heavily subsidized by government, with high consumer pricing supposedly for energy and water 'conservation' (of course while industry gets bulk reduced rates, and while shareholders make record gains). Measured by an integrated metred system with data collation, analysis, and all policy formulation to be carried out by a new 'government' structure, no doubt to be a P3 as other new federal and Ontario infrastructure boards are, heavily embedded with the same players that gathered at this conference.
 
We can do better.
 
Dust off the better studies sitting on the shelf that show there's enough wind and sun on the planet to fuel 6X our current use, and conserve by getting rid of dirty industries, with transition programs for unionized workers to build the renewables, rather than mainly the nonrenewables and nukes. Do all of the above with public power, not the exorbitant costs of privatized P3 power. Eliminate speculation, and pull self-governance from industry heads and investors. Roll-back NAFTA and put a moratorium on further entrenching of the SPP, TILMA, and bilateral deals.
 
Do not use 'renewable energy' to mean building more hydro dams and canals to channel more Hudson Bay Basin water down to the Great Lakes, killing what's left of our wild north for the sake of profiteers who don't have the smarts and humility to shift gears.
 
And above all, read beyond 'green' headlines to expose and reject policy which would entrench the problems.
 
Thanks to all activists for your work for real change, inspite of the kind of nonsense noted here, tossed from various quarters.
 
Our words and actions, of critique and substantive alternatives, are the change we want to see.

Sander's research is OUR CIA! Their latest on CHINA

The Heron's Latest Catch

China drought underlines hydropower reliance risks

By: Emma Graham-Harrison
Date: 28-01-2008

BEIJING (Reuters) - A major drought has squeezed electricity output at big dams across southwest China, highlighting the risks of Beijing's massive hydropower expansion plans on coal and oil markets in a warmer, drier world. Ships are stranded, millions are short on drinking water, and power supplies to big consumers in several Chinese provinces have been cut back, industry officials and local media have said.

And while building more dams will help Beijing meet more of its electricity demand using resources within its own borders, it also risks short-term surges in consumption of oil, coal or natural gas to generate emergency power when rivers run low. . . Other countries like Pakistan and Vietnam that are heavily reliant on hydropower have been forced to step up imports of fuel oil or buy power from neighbours during dry spells, driving up costs for producers and unsettling regional oil markets.

Canada-US crude oil pipeline down; gas prices UP!

Fire and explosion kills 2 shuts main Canada-US crude oil pipeline*

NEW YORK, Nov 28 (Reuters) - A fire and explosion in Minnesota on Wednesday forced Enbridge to shut most of the main pipeline that supplies Canadian crude to Midwest refineries, halting nearly a fifth of U.S. imports and sending prices up $1.

Calgary, Alberta-based Enbridge Inc said all its lines in the vicinity of its Clearbrook, Minnesota, terminal -- Lines 1, 2, 3, and 4 -- were immediately shut down and isolated.

Those are the main trunk lines that carry an estimated 1.9 million barrels per day (bpd) of Canadian crude to the United States.

Enbridge did not give further details about the total line capacity that had been shut down and said it was unable to say when the line might be restarted.

Company spokespeople were not immediately able to offer additional comment.

The explosion took place about 3.0 miles (4.8 km) southeast of the Clearbrook terminal, Enbridge said, adding that appropriate authorities and emergency officials had been notified. The company said it was working with federal and state authorities to begin a thorough
investigation.

Two Enbridge employees were killed in the explosion and fire, the company said in a statement. A spokeswoman for the county said the fire could burn for another three days.

"The area under fire now is 100 feet (30.5 metres) by 100 feet, it is anticipated to burn for up to three days," Jeanine Brand, County Attorney and Public Information Officer for Clearwater County, told Reuters by telephone.

Oil prices rose more than $1 a barrel in Thursday trade on fears that the disruption would tighten supplies, rebounding from a nearly $4 fall a day ago. U.S. crude oil futures were $1.17 higher at $91.79 a barrel by 0445 GMT.

Canada is the biggest supplier of foreign crude to the United States, accounting for almost one-fifth of its over 10 million bpd of imports, government data show. [EIA/IMPORT]

Nearly all of that is delivered via the Enbridge system.

According to the Enbridge Web site, Lines 1, 2, 3 and 4 have a capacity to carry slightly over 1.7 million bpd of crude oil, natural gas liquids and oil products.

"My initial impression is that (this) will put a halt to the slide in oil prices and put us back on the march towards $100 a barrel," ANZ senior commodities analyst Mark Pervan said. "The timing is pretty bad. We are coming to the strongest demand period for crude with the approach
of the northern winter."

PAST LEAKS FIXED QUICKLY

Previous disruptions caused by leaks on the Enbridge system earlier this year have been patched up quickly enough to avoid any significant impact on customer deliveries.

A prolonged outage could have a significant market impact. The Cushing, Oklahoma, delivery point for New York Mercantile Exchange (NYMEX) oil futures is located in the Midwest, although the Enbridge line does not flow directly there.

The fire occurred at a main juncture in the line shortly before the U.S. portion splits into a network of pipes that runs to refiners in Chicago and the U.S. Midwest, a landlocked region that has few other immediate sources of supply.

It supplies 62 percent of the crude refined in the Chicago area and 82 percent of Ontario's demand, according to the Web site of U.S. arm Enbridge Energy Partners, L.P .

The Enbridge System in Canada consists of 8,000 km (5,000 miles) of mainline pipe and connects to the 5,600 km Lakehead System in the United States.

The cause of the explosion has not been determined, Enbridge said, but Clearwater County's Brand said it was due to a leak.

"Apparently, there was an oil leak within the last couple of weeks, crews were around when they finished, and they pressured the pipeline, and crude started spilling from the pipeline, oil sprayed and created an oil spill," she said.
