Integrys Energy Services tapped to supply Chicago's electricity

The same company that heats homes in Chicago has been picked to provide the electricity that powers them.

Integrys Energy Services, a sister company to Peoples Gas, on Friday was named the city's choice to supply electricity to about 1 million Chicagoans. It's the largest such deal negotiated by a city on behalf of its residents.

The City Council is to vote on the contract Wednesday after a Monday public hearing.

Chicagoans should see discounts of 20 to 25 percent from March through June. Afterward, savings are expected to drop. Overall, the average household is expected to save $130 to $150 through May 2015, when the contract ends, according to the mayor's office.

Mayor Rahm Emanuel said Friday the deal "will put money back into the pockets of Chicago families and small businesses."

The contract calls for the elimination of power produced from coal, the largest source of greenhouse gases. About 40 percent of Chicago's electricity is from coal.

"That's a giant step toward healthier air and clean, renewable energy that supports good paying jobs in the technologies of tomorrow," said Jack Darin, executive director of the Sierra Club's Illinois chapter and a member of the advisory committee that worked on the deal.

However, the no-coal provision is largely symbolic since there is no way to know the precise origin of electricity flowing into Chicago homes.

Integrys Energy Services, a subsidiary of Chicago-based Integrys Energy Group, was chosen from eight bidders and was the only company other than Exelon-owned Constellation NewEnergy that made it to the final round.

Integrys Energy Group's board includes William Brodsky, head of the Chicago Board Options Exchange and a member of World Business Chicago, which Emanuel chairs.

The Integrys unit won the electrical aggregation contract despite Emanuel's connection to Constellation through its parent company, Exelon, which also owns Commonwealth Edison. While working at investment banking firm Wasserstein Perella & Co. after leaving the Clinton White House in 1998, Emanuel helped set up the merger that created Exelon.

Price was the determining factor, the mayor's office said.

Bidding documents, including pricing and how the contract would be structured, were not made public Friday.

In picking a price, Integrys must account for a large number of customers that will come and go. If electricity prices rise, Integrys risks losing money. Still, Integrys stands to become a dominant player in the retail electricity business and gain about $300 million in yearly revenue.

"Scale is important in this business," said Travis Miller, a utilities analyst with Chicago-based Morningstar. "The winner is immediately going to gain a huge scale advantage within the retail market."

ComEd still will be responsible for delivering electricity and fixing outages. ComEd makes its money delivering electricity, not supplying it. Customers' new bills will look like the old bills, except that the portion titled "electricity supply services" will have a new rate and include the new supplier's name.

Chicagoans can opt out and stick with ComEd or choose their own supplier like thousands of people already have.

Supreme Court to review gay marriage cases

The Supreme Court will take up California's ban on same-sex marriage, a case that could give the justices the chance to rule on whether gay Americans have the same constitutional right to marry as heterosexuals.

The justices said Friday they will review a federal appeals court ruling that struck down the state's gay marriage ban, though on narrow grounds. The San Francisco-based appeals court said the state could not take away the same-sex marriage right that had been granted by California's Supreme Court.

The court also will decide whether Congress can deprive legally married gay couples of federal benefits otherwise available to married people. A provision of the federal Defense of Marriage Act limits a range of health and pension benefits, as well as favorable tax treatment, to heterosexual couples.

The cases probably will be argued in March, with decisions expected by late June.

Gay marriage is legal, or will be soon, in nine states — Connecticut, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New York, Vermont, Washington — and the District of Columbia. Federal courts in California have struck down the state's constitutional ban on same-sex marriage, but that ruling has not taken effect while the issue is being appealed.

Voters in Maine, Maryland and Washington approved gay marriage earlier this month.

But 31 states have amended their constitutions to prohibit same-sex marriage. North Carolina was the most recent example in May. In Minnesota earlier this month, voters defeated a proposal to enshrine a ban on gay marriage in that state's constitution.

The biggest potential issue before the justices comes in the dispute over California's Proposition 8, the state constitutional ban on gay marriage that voters adopted in 2008 after the state Supreme Court ruled that gay Californians could marry. The case could allow the justices to decide whether the U.S. Constitution's guarantee of equal protection means that the right to marriage cannot be limited to heterosexuals.

A decision in favor of gay marriage could set a national rule and overturn every state constitutional provision and law banning same-sex marriages. A ruling that upheld California's ban would be a setback for gay marriage proponents in the nation's largest state, although it would leave open the state-by-state effort to allow gays and lesbians to marry.

In striking down Proposition 8, the 9th U.S. Circuit Court of Appeals crafted a narrow ruling that said because gay Californians already had been given the right to marry, the state could not later take it away. The ruling studiously avoided any sweeping pronouncements.

The larger constitutional issue almost certainly will be presented to the court, but the justices would not necessarily have to rule on it.

The other issue the high court will take on involves a provision of the Defense of Marriage Act, known by its acronym DOMA, which defines marriage as between a man and a woman for the purpose of deciding who can receive a range of federal benefits.

Four federal district courts and two appeals courts struck down the provision.

The justices chose for their review the case of 83-year-old Edith Windsor, who sued to challenge a $363,000 federal estate tax bill after her partner of 44 years died in 2009.

Windsor, who goes by Edie, married Thea Spyer in 2007 after doctors told them that Spyer would not live much longer. She suffered from multiple sclerosis for many years. Spyer left everything she had to Windsor.

There is no dispute that if Windsor had been married to a man, her estate tax bill would have been $0.

The 2nd U.S. Circuit Court of Appeals in New York agreed with a district judge that the provision of DOMA deprived Windsor of the constitutional guarantee of equal protection.

TechCrunch’s  Drew Olanoff got a little too excited on Friday and thought a single in-stream photo meant that Instagram was allowing its Twitter cards back on Twitter and thought the two services were planning a sudden reunion. You may have seen some, too, but a Facebook spokesperson assured users these Instagram photos on Twitter were the last holdouts in the switchover. ”What you are seeing now may be some sort of regression depending on the mobile client, but we’re checking in with the engineers,” read Facebook’s statement, via Talking Points Memo’s Carl Franzen.

The New Old Age Blog: A Son Lost, a Mother Found

My friend Yvonne was already at the front door when I woke, so at first I didn’t realize that my mother was missing.

It was less than a week after my son Spencer died. Since that day, a constant stream of friends had been coming and going, bringing casseroles and soup, love, support and chatter. Mom hated it.

My 94-year-old mother, who has vascular dementia, has been living in my home in upstate New York for the past few years. Like many with dementia, mom is courteous but, underneath, irascible. Pride defines her, especially pride in her Phi Beta Kappa intellect. She hates to be confronted with how she has become, as she calls it, “stupid.”

The parade of strangers confused her. She had to be polite, field solicitous questions, endure mundane comments. She could not remember what was going on or why people were there. It must have been stressful and annoying.

That night, like every night since the state troopers brought the news, I woke hourly, tumbling in panic. As if it were not too late to save my son. Mom knew something was wrong, but she could not remember what. As I overslept that morning, she must have decided enough was enough. She was going home.

In a cold sky, the sun blazed over tall pines. As I opened the door, the dogs raced out to greet Yvonne and her two housecleaners. Yvonne often brags about her cleaning duo. They were her gift to me. They were going to clean my house before the funeral reception, which was scheduled for later that week. This was a very big gift because, like my mother before me, I am a very bad housekeeper.

Mom’s door was shut. I cautioned the housecleaners to avoid her room as I showed them around. Yvonne went to the kitchen to listen to the 37 unheard messages on my answering machine; the housecleaners went out to their van to get their instruments of dirt removal.

I ducked into Mom’s room to warn her about the upcoming noise. The bed was unmade; the floor was littered with crumpled tissues; the room was empty.

Normally, I would have freaked out right then. I knew Mom was not in the house, because I had just shown the whole house to the cleaners. Although Mom doesn’t wander like some dementia patients, she does on occasion run away. But I could not muster a shred of anxiety.

“Yvonne,” I called, “did you see my mother outside?”

Yvonne popped her head into the living room, eyebrows raised.“Outside? No!” She was alarmed. “Is she missing?”

“Yeah,” I said wearily, “I’ll look.” I stepped out onto the front porch, tightening the belt of my bathrobe and turning up the collar. Maybe she had walked off into the woods. The dogs danced around my legs, wanting breakfast.

I had no space left in my body to care. Either we would find her, or we would not. Either she was alive, or she was not. My child was gone. How could I care about anything ever again?

Then I saw my car was missing. My mouth fell open and my eyeballs rolled up to the right, gazing blindly at the abandoned bird’s nest on top of the porch light: What had I done with the keys?

Mom likes to run away in the car when she is angry. She used to do it a lot when my father was still alive — every time they fought. Since Mom took off in my car almost a year ago, after we had had a fight, I’d kept the keys hidden. Except for this week; this week, I had forgotten.

I was reverting to old habits. I had left the doors unlocked and the keys in the cupholder next to the driver’s seat. Exactly like Mom used to do.

“Uh-oh,” I said aloud. Mom was still capable of driving, even though she did not know where she was going. I just really, really hoped that she didn’t hurt anybody on the road. I pulled out my cellphone, about to call the police.

“Celia!” Yvonne shouted from the kitchen. She hurried up behind me, excited. “They found your mother. There are two messages on your machine.”

At that very moment, Mom was holed up at the College Diner in New Paltz, a 20-minute drive over the mountain, through the fields, left over the Wallkill River and away down Main Street.

Yvonne called the diner. They promised to keep the car keys until someone arrived. By that time, Yvonne had to go to work. She drove my friend Elizabeth to the diner, and Elizabeth drove Mom home in my car.

Half an hour later, they walked in the front door. Mom’s cheeks were rouged by the chill air and her eyes sparkled, her white hair riffing with static electricity. “Hello, hello,” she sang out. “Here we are.” She was wearing the flannel nightgown and robe I had dressed her in the night before. It was covered by her oversized purple parka, and her bare feet were shoved into sneakers.

I started laughing as soon as I saw her. I couldn’t help it. Elizabeth and Mom started laughing too. “You had a big adventure,” I said, hugging them both. “How are you?”

“I’m just marvelous,” said my mother. Mom always feels great after doing something rakish. We settled her on the sofa with her feet on the ottoman. By the time I got her blanket tucked in around her shoulders, she had fallen asleep.

Elizabeth couldn’t stop laughing as she described the scene. “Your mother was holding court in this big booth. She was sitting there in her nightgown and her parka, talking to everybody, with this plate of toast and coffee and, like, three of the staff hovering around her.”

The waitress said Mom seemed “a little disoriented” when she got there. Mom said she was meeting a friend for breakfast, but since she was wearing a nightgown and didn’t know whom she was meeting or where she lived, the staff thought there might be a problem. They convinced Mom to let them look in the glove compartment of the car, where they found my name and number.

It was then that I realized I was laughing – something I’d thought I would never be able to do again. “Elizabeth, Elizabeth, I’m laughing,” I said.

“Ha, ha, ha,” laughed Elizabeth, holding her belly.

“Ha, ha, ha,” I laughed, rolling on the floor.

And she who gave me life, who had suffered the death of my child and the extinction of her own intellect, snoozed on: oblivious, jubilant, still herself, still mine.

O'Hare affected by United's latest computer glitch

United Airlines experienced more computer problems Friday, causing systems to slow down.

"We have been experiencing short-term, intermittent Internet connectivity issues, causing some systems to run more slowly than normal," United spokesman Rahsaan Johnson said.

However, the airline is continuing to operate flights and "take care of customers," he said, adding that interruptions last for about five minutes.

The problem is only at some locations, including Chicago O'Hare International Airport, he said.

The glitch has not harmed the airline's on-time performance, which was running at 91.5 percent for United Airlines flights and about 85 percent for United Express flights, he said. Those rates are higher than normal for United, which has been running closer to 80 percent on time.

Computer problems have plagued the airline this year, starting in March when it switched to a new reservations system. During the summer its operations were especially poor, with rampant flight delays and cancellations.

Preckwinkle rips Emanuel, McCarthy's handling of violence

Cook County Board President Toni Preckwinkle today publicly blasted Mayor Rahm Emanuel’s crime-fighting strategy and the quality of the public schools he controls, then quickly walked back the remarks.

The Democratic leader said her criticism was targeted at society as a whole and not the mayor personally, much as she did last summer when she harshly criticized former President Ronald Reagan for his role in the war on drugs.

The comments about Emanuel came during a question-and-answer session during a luncheon at the Union League Club. Preckwinkle was asked how to address Chicago violence.

“Clearly, this mayor and this police chief have decided the way in which they are going to deal with the terrible violence that faces our community is just arrest everybody,” Preckwinkle said. “I don’t think in the long term that’s going to be successful.

“We’re going to have to figure out how to have interventions that are more comprehensive than just police interventions in the communities where we have the highest rates of crime. And they’re almost all in African-American and Latino communities.”

Homicides and shootings in Chicago have attracted national attention this year following a spike in the city’s murder rate and brazen incidents such as the shooting of a young man at a funeral for a gang member.

Preckwinkle said much of the problem results from a school system that has a low high school graduation rate.

“We have contented ourselves with a miserable education system that has failed many of our children,” Preckwinkle said, saying more after-school enrichment and job-training programs are needed. “I’m talking about the kids who don’t graduate, let alone the kids who graduate don’t get a very good education, even with a high school diploma.”

Emanuel aides responded with restraint, saying the mayor is taking many of the actions Preckwinkle said were needed, even as he maintained a tough stance on crime.

“Mayor Emanuel strenuously agrees that a holistic approach is necessary to successfully address crime,” Emanuel spokeswoman Sarah Hamilton said in a statement. “His multi-part strategy ranges from improving early childhood education, providing a longer school day and creating re-engagement centers for youth, to delivering wrap-around services, revitalizing the community policing program and working to prevent retaliatory actions by gangs.

“All of these work in tandem, but let's make no mistake, criminals deserve to be arrested,” the statement read.

At a news conference after her speech and question session, Preckwinkle said her criticism of schools wasn’t aimed at Emanuel, who as mayor appoints the Chicago Public Schools board and picks the system’s CEO.

“This was a critique of all of us, it wasn’t aimed at the mayor,” said Preckwinkle, a former CPS high school history teacher.

Preckwinkle also acknowledged that Emanuel is putting more city money into early childhood education, after-school programs and youth job programs — in part through programs coordinated with the county.

Her point, she said, was that education over the long run will do more to quell violence than arresting people and locking them up.

“You know unfortunately we live in a country in which we are much more willing to spend money on keeping people in prison than we are on educating them in our public schools,” she said. “And that’s disgraceful. It reflects badly on all of us.”

She added, “I don’t think we are going to arrest our way out of our violence problems.”

Mayor Emanuel's aides said they just learned of the remarks and are preparing a response.

Preckwinkle is a liberal who has been consistently critical of a justice system that locks up African-American and Latino men in far greater numbers than their white counterparts, particularly for drug crimes when studies show drugs are used in equal numbers across ethnic and racial boundaries

It wasn’t the first time that, while speaking without a script, she made comments that ruffled some feathers.

In August, she said former President Ronald Reagan deserved “a special place in hell” for his role in the War on Drugs, later saying she regretted the “inflammatory” remark.

Zynga moves to enter US gambling market

NEW YORK (AP) — Online games company Zynga said it has asked Nevada gambling regulators for a decision that could pave the way for it to enter the U.S. gambling market.

This follows Zynga’s October disclosure that it has signed a deal to offer online poker and casino games, played with real money, in the U.K. It plans to launch those games in the first half of 2013.

Zynga Inc. said in an email late Wednesday that it is seeking an “application for a preliminary finding of suitability” from the Nevada Gaming Control Board. This, the company says, is part of its plan to enter regulated “real-money gaming,” that is, gambling markets.

Zynga has not said what it plans to do with a gaming license. But the company, whose games are played primarily on Facebook, has faltered in recent months and is looking for additional revenue sources beyond online games such as “FarmVille 2″ and “Words With Friends.”

The San Francisco-based company says the process with Nevada regulators should take 12 to 18 months. If Zynga passes the first regulatory hurdle, it can then apply for a gaming license in the state. That, the company said, takes two to three months.

Zynga’s stock rose 17 cents, or 7.1 percent, to close Thursday at $ 2.49. The company went public about a year ago, when its stock priced at $ 10 per share.

“Breaking Bad,” dominates Writers Guild TV nominations

LOS ANGELES (Reuters) – Dark drug drama “Breaking Bad” dominated television nominations for the annual Writers Guild Awards on Thursday, with “Modern Family” leading the way in the comedy category.

A trio of HBO newcomers – Lena Dunham‘s “Girls,” Aaron Sorkin‘s “The Newsroom,” and political satire “Veep” – will compete in the new series category, along with network comedy “The Mindy Project” and country music drama “Nashville,” the Writers Guild of America (WGA) announced.

“Girls,” the story of three 20-somethings navigating life and love in New York City, also won a nomination in the best comedy series slot, along with established shows “30 Rock,” “Parks and Recreation,” “Louie” and Emmy darling “Modern Family.”

The Writers Guild recognizes achievements in the writing of U.S. television, radio, news and animation, rather than actors or directors. The Guild will announce its nominations in the movie field in January.

“Breaking Bad,” starring Bryan Cranston as a teacher turned drug kingpin and now in its fifth and final season, picked up five nods on Wednesday, including best drama series and four for individual episodes.

The show is likely to face stiff competition from psychological thriller “Homeland,” which won the WGA’s award for best new drama last year and has since bagged an Emmy and Golden Globe.

“Mad Men,” lavish Prohibition-era show “Boardwalk Empire,” and fantasy series “Game of Thrones,” round out the competition for best drama series.

In longer form television, miniseries “Hatfields and McCoys” – about a 100 year-old family feud – was nominated along with TV film “Hemingway and Gelhorn” and “Political Animals.”

The WGA will hand out its awards in all categories on February 17 at simultaneous ceremonies in both New York and Los Angeles.

Extended Use of Breast Cancer Drug Suggested

The widely prescribed drug tamoxifen already plays a major role in reducing the risk of death from breast cancer. But a new study suggests that women should be taking the drug for twice as long as is now customary, a finding that could upend the standard that has been in place for about 15 years.

In the study, patients who continued taking tamoxifen for 10 years were less likely to have the cancer come back or to die from the disease than women who took the drug for only five years, the current standard of care.

“Certainly, the advice to stop in five years should not stand,” said Prof. Richard Peto, a medical statistician at Oxford University and senior author of the study, which was published in The Lancet on Wednesday and presented at the San Antonio Breast Cancer Symposium.

Breast cancer specialists not involved in the study said the results could have the biggest impact on premenopausal women, who account for a fifth to a quarter of new breast cancer cases. Postmenopausal women tend to take different drugs, but some experts said the results suggest that those drugs might be taken for a longer duration as well.

“We’ve been waiting for this result,” said Dr. Robert W. Carlson, a professor of medicine at Stanford University. “I think it is especially practice-changing in premenopausal women because the results do favor a 10-year regimen.”

Dr. Eric P. Winer, chief of women’s cancers at the Dana-Farber Cancer Institute in Boston, said that even women who completed their five years of tamoxifen months or years ago might consider starting on the drug again.

Tamoxifen blocks the effect of the hormone estrogen, which fuels tumor growth in estrogen receptor-positive cancers that account for about 65 percent of cases in premenopausal women. Some small studies in the 1990s suggested that there was no benefit to using tamoxifen longer than five years, so that has been the standard.

About 227,000 cases of breast cancer are diagnosed each year in the United States, and an estimated 30,000 of them are in premenopausal women with estrogen receptor-positive cancer and prime candidates for tamoxifen. But postmenopausal women also take tamoxifen if they cannot tolerate the alternative drugs, known as aromatase inhibitors.

The new study, known as Atlas, included nearly 7,000 women with ER-positive disease who had completed five years of tamoxifen. They came from about three dozen countries. Half were chosen at random to take the drug another five years, while the others were told to stop.

In the group assigned to take tamoxifen for 10 years, 21.4 percent had a recurrence of breast cancer in the ensuing 10 years, meaning the period 5 to 14 years after their diagnoses. The recurrence rate for those who took only five years of tamoxifen was 25.1 percent.

About 12.2 percent of those in the 10-year treatment group died from breast cancer, compared with 15 percent for those in the control group.

There was virtually no difference in death and recurrence between the two groups during the five years of extra tamoxifen. The difference came in later years, suggesting that tamoxifen has a carry-over effect that lasts long after women stop taking it.

Whether these differences are big enough to cause women to take the drug for twice as long remains to be seen.

“The treatment effect is real, but it’s modest,” said Dr. Paul E. Goss, director of breast cancer research at the Massachusetts General Hospital.

Tamoxifen has side effects, including endometrial cancer, blood clots and hot flashes, which cause many women to stop taking the drug. In the Atlas trial, it appears that roughly 40 percent of the patients assigned to take tamoxifen for the additional five years stopped prematurely.

Some 3.1 percent of those taking the extra five years of tamoxifen got endometrial cancer versus 1.6 percent in the control group. However, only 0.6 percent of those in the longer treatment group died from endometrial cancer or pulmonary blood clots, compared with 0.4 percent in the control group.

“Over all, the benefits of extended tamoxifen seemed to outweigh the risks substantially,” Trevor J. Powles of the Cancer Center London, said in a commentary published by The Lancet.

Dr. Judy E. Garber, director of the Center for Cancer Genetics and Prevention at Dana-Farber, said many women have a love-hate relationship with hormone therapies.

“They don’t feel well on them, but it’s their safety net,” said Dr. Garber, who added that the news would be welcomed by many patients who would like to stay on the drug. “I have patients who agonize about this, people who are coming to the end of their tamoxifen.”

Emily Behrend, who is a few months from finishing her five years on tamoxifen, said she would definitely consider another five years. “If it can keep the cancer away, I’m all for it,” said Ms. Behrend, 39, a single mother in Tomball, Tex. She is taking the antidepressant Effexor to help control the night sweats and hot flashes caused by tamoxifen.

Cost is not considered a huge barrier to taking tamoxifen longer because the drug can be obtained for less than $200 a year.

The results, while answering one question, raise many new ones, including whether even more than 10 years of treatment would be better still.

Perhaps the most important question is what the results mean for postmenopausal women. Even many women who are premenopausal at the time of diagnosis will pass through menopause by the time they finish their first five years of tamoxifen, or will have been pushed into menopause by chemotherapy.

Postmenopausal patients tend to take aromatase inhibitors like anastrozole or letrozole, which are more effective than tamoxifen at preventing breast cancer recurrence, though they do not work for premenopausal women.

Mr. Peto said he thought the results of the Atlas study would “apply to endocrine therapy in general,” meaning that 10 years of an aromatase inhibitor would be better than five years. Other doctors were not so sure.

The Atlas study was paid for by various organizations including the United States Army, the British government and AstraZeneca, which makes the brand-name version of tamoxifen.
