This paper presents a novel optimization technique using genetic algorithms to develop an optimized emergency defence plan for power systems. The technique determines the optimal combination of generator tripping, load shedding, and islanding to regain system stability following severe contingencies. It was applied to the Libyan power system using time-domain simulations to evaluate solutions. Results showed the optimized defence plan required less load shedding than the existing Libyan plan and improved system response during a 2003 blackout event.

Vicinity Jobs’ data includes more than three million 2023 OJPs and thousands of skills. Most skills appear in less than 0.02% of job postings, so most postings rely on a small subset of commonly used terms, like teamwork.
Laura Adkins-Hackett, Economist, LMIC, and Sukriti Trehan, Data Scientist, LMIC, presented their research exploring trends in the skills listed in OJPs to develop a deeper understanding of in-demand skills. This research project uses pointwise mutual information and other methods to extract more information about common skills from the relationships between skills, occupations and regions.
In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.

1 INTRODUCTION
During 20 10, the De Zalze's HOA Board of Directors
approved a 5 year plan for electricity with the following
objectives:
Reduction of electricity cost
Improved energy efficiency
Reduced impact on the environment
Energy initiatives can generally not be implemented
overnight and it takes some time for new ideas to gain
acceptance. However, it is now nearly 5 years later and
this report takes an early view of trends in the main
indicators to establish if the Estate is still on the right
track. Investments have been made with the expectation
of positive outcomes.
The biggest challenge is always to get wide
participation from residents on a large Estate with diverse
interests, especially where electricity cost does not form a
major part of the expense of the average household. There
is however a growing environmental awareness, which
includes concerns over scarce resources such as electricity
and water and more recently, the threat of load shedding.
The initiatives that were introduced included energy
efficiency awareness, smart metering, time-of-use tariffs,
timers and guidelines for individual own generation such
as solar. De Zalze buys its electricity directly from
Eskom at the Miniflex tariff and the Estate's policy
dictates the recovery of actual electricity costs from the
residents.
the total consumption trend, average purchase price from
Eskom, average price paid by the De Zalze's residents
compared to nearby municipalities and the percentage
power used during peak hours, both morning and evening
peaks. These indicators all show positive trends and
confirmed that De Zalze is on the right track. However, it
still requires wider participation from more consumers on
the Estate.
2 ELECTRICITY STRUCTURE
De Zalze buys its electricity directly from Eskom at a
tariff called Miniflex, which is the best available tariff
structure for the Estate taking into account the
consumption profiles of De Zalze. It is predominantly
based on the energy consumed and has 6 time periods
with differentiated pricing. The time periods consist of
Peak, Standard and Off-peak categories for summer and
for winter, with the winter peak pricing at a very high
level.
The major consumer groups on the Estate are:
i. Wine Cellar, restaurant and lodges
ii. De Zalze Golf Club
iii. Holiday Lodges
iv. HOA Offices, pumps, street lights and workshops
v. 4 18 houses
Although, the purchase tariff from Eskom was time/price
differentiated, prior to Apr 20 13, the De Zalze's
consumers were purchasing electricity at a single flat rate
regardless of the time of day or season. There was
therefore a total disconnect between the price signal that
the residents experienced and the pricing structure from
Eskom.
The Eskom Time of Use periods are shown in Figure 1.

5 RESULTS
5. 1 RELATIVE REDUCTION OF ELECTRICITY
COST
Figure 2 shows the average purchase price of electricity
from Eskom compared to the average price paid by a
resident at De Zalze and prices paid by City of Cape
Town and Stellenbosch residents. The prices were
calculated using the average De Zalze resident's
consumption as reference. The following comments can
be made in relation to the interventions listed in Section 3:
• The De Zalze's prices stayed more or less the same
since 20 12/13 compared to the current level when
compared to the other prices, mainly because:
o Lower purchase cost due to load shifting,
probably as a result of geyser and pool
timers
o Introduction of Critical Peak Day (CPD)
Pricing
o Increased energy efficiency awareness
• The reduction in price from 20 131 14 to 20 14115
could be as a result of:
o Residents' response to the Time of Use
pricing signal which was introduced in April
20 14. Many residents introduced timers on
their geysers and undertloor heating which
had a considerable impact on the winter load
profile
o The inclusion of the Critical Peak Day
Pricing in the end-user tariff to residents

consumption during the evening peak between 18:00 and
20:00. It can also be seen that load shedding took place
between 14:00 and 16:00. Only the peak areas are
highlighted in the graph and the standard and off-peak
areas are not separated.

Fig.ure 4. A Village consumption daily profile (one of many)
The consumption during peak hours has reduced
slightly over the past few years as can be seen from
Figure 5, but this is expected to get better as more
residents become aware of the benefit of shifting
consumption out of peak periods. Peak hours make up
14.8% of the total hours in a week. Some residents have
already achieved a peak percentage of below 10%.

The effect of reduced peak consumption on the
average cost of electricity is shown in Figure 6 and it is
obviously much more beneficial during winter months. A
peak reduction from 22% to 9% of total consumption, will
reduce the overall average price in winter by 27% and by
14% in summer.

combined into one Off-peak period for the Estate to
simplify the tariff.
5.2 ENERGY EFFICIENCY IMPROVEMENTS
The measurement of energy efficiency improvement on
the Estate is viewed through the trend on the overall
annual electricity consumption on the De Zalze and the
average monthly consumption of individual residents.
De Zalze's electricity consumption, excluding the wine
cellar, is shown in Figure 8. It has decreased from a peak
of 8 927 MWh per year in 20 101 1I to 7 967 MWh in
20 141 15. This is a reduction of 10.8% despite an increase
in metered consumers from 403 to 4 19 for the same
period. In addition, the average consumption per resident
per month has reduced from 1846 kWh in 20 101 1I to
1585 kWh in 20 141 15 or by 14.2%.
The reasons for this can most probably be attributed to:
vi. More awareness of electricity consumption and cost
vii. Deliberate energy efficiency improvements such as,
solar water heating, heat pumps, LED and CFL
lighting, geyser timers, shower heads, etc.

6 CONCLUSION
This analysis indicates that the De Zalze Estate is on the
right track with its energy management programme. The
main challenge is to get wider participation by more
residents in response to the electricity pricing signal. It
seems that only 25% of the Estate's residents are
responding to electricity prices and energy efficiency
ideals at this stage. The possible reasons for this could
include:
viii. Electricity is seen as a necessary commodity,
whatever the price.
ix. Electricity is Eskom's problem
x. Insufficient understanding of potential solutions
xi. Low priority item
The challenge is to increase awareness of the
environmental impact that electricity generation from coal
has in this country. The delays in the commissioning of
Medupi Power Station, the Eskom load shedding crisis
and electricity increases certainly helps to increase
awareness of the increased scarcity of electricity, but
unfortunately in a negative sense.
The ideal world for the Estate would be:
xii. Control all geysers, pool pumps and underfloor
heating to switch off during peak times
xiii. Widespread installation of photo voltaic systems and
UPS
xiv. Heat pumps or solar water heating
xv. Consideration of gas for cooking
xvi. Energy efficient lighting everywhere
xvii. Efficient ceiling insulation at all houses
Economic considerations will not be the driver for the
introduction of PV systems at De Zalze as a result of the
low electricity price on the Estate, but will rather be
driven by the need to overcome the effects of power
interruptions and environmental awareness.
