Many companies are at a standstill, or are only running at half power, which has caused electricity consumption in Belgium to fall by 16%, and prices on the wholesale market have been dropping below zero for four weekends in a row.
“We shut down wind farms at sea on Monday because the electricity they produced only costs us money,” said Pieter Verlinden, purchasing manager at the green energy supplier Eneco to De Tijd.
Normally, the sale of a megawatt-hour of electricity in the professional day trade generates €40 to 50. However, on Easter Monday, the situation was just the other way round and operators of wind farms or power stations had to pay €115 themselves for every megawatt-hour they produced.
“I do not remember ever experiencing such a dramatic price dip,” said Kris Voorspools, manager of the 70GigaWatt energy consultant agency, according to NewMobility. “Prices on Monday were negative for thirteen hours. That’s unprecedented,” he added.
As electricity is difficult to store, supply and demand must be balanced at all times. The negative prices serve to eliminate oversupply, making sure that the grid does not become overloaded. By making producers on the wholesale market pay for the electricity they supply, they are encouraged to reduce their production.
On Monday, the Belgian nuclear power stations constantly supplied 4 gigawatts of electricity, but in the afternoon, more than 1 gigawatt of wind production was switched off to avoid overloading the grid.
“It is very strange that when there is a lack of flexibility, the nuclear power plants continue to run at full capacity,” said Voorspools. “In our neighbouring countries, there were also negative prices, but in Germany and France, for example, this led to a decline in nuclear production,” he added.
Engie Electrabel, the operator of the Belgian nuclear power plants, referred to the coronavirus measures. “The nuclear power plants are currently operating with two-thirds fewer people,” said spokesperson Anne-Sophie Hugé to De Tijd.
“In these special circumstances, we want to minimise the disruption to the power plants and keep them stable at 100%. Only if the grid is in danger and [Belgian transmission system operator for high-voltage electricity] Elia asks us to do so, we will modulate the production, but we are not going to do so for economic reasons,” she added.
The continued negative prices create substantial losses for suppliers, who have been buying power volumes long in advance to supply the customers with. “However, because of the coronavirus pandemic, consumption is much lower than expected. We have to sell some of the overbought volumes,” said Verlinden of Eneco. “In a market where prices are low and even negative, that leads to heavy losses. This situation is not healthy for anyone,” he added.Q: Sqlalchemy joint filter with potentially empty child object list I have two classes in my code: a Person with the name and its Nicknames:
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String
Base = declarative_base()

class Person(Base):
    __tablename__ = 'person'
    id = Column(Integer, primary_key=True)
    name = Column(String(10))
    nicknames = relationship('Nickname', 
                             back_populates = 'person')

class Nickname(Base):
    __tablename__ = 'nickname'
    id = Column(Integer, primary_key=True)
    value = Column(String(10))
    person_id = Column(Integer, ForeignKey('person.id'))
    person = relationship('Person', back_populates = 'nicknames')

I want to query a person where given text equals Person.name column or equals Nickname.value.
However, Person.nicknames list could be empty. Therefore, the following query ignores the persons with empty nicknames:
query(Person).join(Nickname).\
              filter(or_(Person.name == text, 
                         Nickname.value == text)).\
              first()

To work-around this possible "emptiness" I construct a query as follows:
q1 = session.query(Person).filter(Person.name == text)

q2 = session.query(Person).join(Nickname).filter(Nickname.value == text)

person = q1.union(q2).first()

Is there a way to pack two queries in one using joins?
I.e. to seach among the names first, and then to check all the nicknames if any.
Searching for the next great wine investment
Tom Gearing grew up in the world of fine wine with a father who was an avid collector, so it may not seem that strange the he founded one of the first wine investment firms in the world. After growing up in England with many buying trips with his father to Burgundy, Bordeaux and other fine wine regions of Europe, Gearing decided to establish his company while still in college. With help from his investment banker father, they set up an office in their house and launched Cult Wine Investment in 2007. Today that business has $320 million worth of assets under management, 1.25 million bottles of wine in their temperature controlled warehouses, and employs over 100 professionals with clients located in 83 countries.
“Many people don’t realize that fine wine has a solid investment track record. For example, since 2009, the Cult Wines Index returned +194% (8.89 CAGR),” reports Gearing. “Even in the challenging 2022 market, our second quarter return was +4.73%.” During that same quarter the S&P was down -16.1% and the Nasdaq was -22.47%.
“In general,” Gearing continues, “fine wine has an overall return of around 9 to 10% per year.” However, there have been some very healthy returns on individual wine brands. For example, according to Cult Wine’s database, Emidio Pepe Montepulciano d’Abruzzo from Italy achieved a 78% return over 3 years; whereas Chateau Rayas from Chateauneuf de Pape in the Rhone region of France climbed 198% over the same time period.

“Fine wine investing is a good way to diversify a portfolio,” states Gearing. “Plus there is always the option to drink the wine at a later time if you decide not to sell it.”
Creating a Fine Wine Investment Portfolio
Just as investors make the decision of what percentage of blue chip stocks, small caps, emerging market, and other categories they want in their portfolio, so do wine investors. “We work with each investor to develop a fine wine investment strategy,” explains Gearing. “For example, if they prefer lower risk but with more modest returns, we generally invest in ‘blue chip’ wines such as Bordeaux and Burgundy, which have a solid track record. But if they want exposure to the most exciting and upcoming wines from new producers or regions, we may create a combined portfolio of emerging producers combined with ‘blue chip’ wine producers.”
Gearing explains that the minimum investment time for fine wine is 3 to 5 years, so in creating a personalized portfolio for each investor they not only consider risk appetite, but also time horizon and investment level. For example, one portfolio may consist primarily of wines from Bordeaux, Burgundy, Champagne and California; while another includes all of these, plus wines from Rhone, Italy, and other parts of the world. In tracking wine and region performance, Cult Wines also works closely with Liv.ex and the Liv.ex 1000 index, the broadest measure of the fine wine market.
