Taking control − three easy steps to drive performance
▲ Encompass, AMR and sub-meters work together to
empower the energy manager and facilities.
▲ Building Management systems are centralised and
optimised from data analysis.
▲ Site audits can focus on specific issues already identified.
▲ We have also acquired and implemented the prestigious
ISO 50001 Energy Management System to ensure effective
energy monitoring & were the first of the ‘Big 6’ to achieve
▲ The SKA system is used for all major site refits, npower is
currently UK and World leader with 7 Gold awards.
▲ System ensures all refits are conducted in a sustainable
and energy efficient way at no additional cost.
▲ It includes a list of recommended energy efficient
▲ If this is adhered to and refits are conducted in an
innovative way then a Ska standard can be awarded – we
achieve the Gold standard on all our refits.
▲ Benefits include an enhanced capital allowance and a
brilliant place to work.
▲ Energy Performance contracts trialled.
▲ State of the art UPS systems installed in Limewood House
and Rainton House
▲ Fantastic energy savings from PIRs, LED lighting
▲ Voltage optimisation at 11 major sites.
▲ Smart STOR generators to generate revenue and reduce
TNUoS charges through the npower TRIAD prediction
▲ Using the EASY initiative (Environment, Action,
Sustainability, You) to engage the workforce, empower
individuals and unify sustainable activities.

Building on the basics
▲ Flexible Purchasing
▲ By combining our site supplies into one group account we took
advantage of npower’s flex contract, whilst being the first ever
customer allowing us to test the contracts and strategy setting.
▲ In 2013 we saw a 12% (£297,225) saving against an equivalent
fixed-contract energy price.

Building on the basics
▲ Leading The Way In Princes Way
▲ Ska Gold rated refit including the Energy
Innovation Centre – 3rd floor A-block.
▲ 44MWh generated by Solar PV at Princes
Way – enough to power the site for two
▲ STOR generation at site capable of net
export during peak times with a second
generator currently being fitted.
▲ Sub-metering with AMR installed to better
understand energy consumption.
▲ This has resulted in a brilliant place to work
and to show our customers how an energy
company manages it’s energy.
▲ Total income from wind, solar and STOR in
excess of £175k p.a.
Across RWE Group UK
Driving performance with the CRC Energy
Efficiency Scheme & ESOS
The npower Sustainability team is also
responsible for managing the CRC Energy
Efficiency Scheme, Carbon Trust Standard
and ESOS submissions for all RWE Group
companies in the UK.
The team drive reductions in CO2 emissions
across Trading, Generation, Energy Services
and Retail arms of the company.
This reduces the spend on CO2 permits, which
is currently in excess of £270k at £12 per Tonne
with permits going up this year. This allows us to
engage customers with the success of our
Our ISO50001 accreditation also aids ESOS
compliance & helped finalise our >70TWh ESOS
submission for RWE in the UK.
Our next steps
Driving Performance –
Further refine data analysis
Challenge – Install
Focus – Develop new
finance opportunities to reduce
our CAPEX spend
Collaboration – Work with
I&C, SME and Energy Service
to develop new products
Customer First – Share our energy efficiency
journey with I&C and SME customers
Accountability – Review performance with
external audits which has led to several awards
Respect – Continue to respect
the needs of our employees and customers.

Building a Hedging Strategy that fits your Risk Appetite
To build an effective risk management strategy we need to set risk appetites against four key parameters:
The budget level will control the degree to which you are happy to let the market move from ‘today’s’ levels in order to preserve downside
opportunity. It is essentially your risk capital
The hedging window is the amount of time you wish to hedge volume for, a long period will provide greater opportunity to hit markets averages
while shorter windows increase the level of fundamental understanding. The Hedge deadline determines how far in advance of delivery you wish to
be 100% hedged and know your final achieved price
The holding period and path flexibility control the level of flexibility afforded to trade execution in order to optimise based on market
intelligence. Opportunity vs. Emotion
The exposure to prompt markets – determines your contract mix. Seasons vs. Quarters vs. Months or day-ahead
14% Hedged Monthly
86% Volume Hedged Before Seasonal Contract Expires
Setting the Budget
Part of a successful risk management
strategy is understanding your budget
By understanding your maximum and
target commodity costs you can ensure
you stay within those limits.
‘Contracted Budgets’ will ensure you lock
in wholesale prices before they rise too
Our systems will be configured to provide
warnings based on observed volatility
and VAR in a single day.
Budgets can be set at contract level or
broken down seasonally.
‘Target Price Levels’ allow you to close
out positions to secure lower wholesale
rates in case they rise again
These don’t have to be set if you do not
want to limit potential gains.
The DBM Platinum product contractually guarantees you
will not fall below your commodity budget
Target Price Level
Budget price = forward market + volatility allowance
Summer 2016 Baseload = £40/MWh
Volatility allowance = 10%
Budget = £45/MWh * 110% = £44/MWh
Close out to limit upside risk
Close out to lock in profits
The optimisation desk’s approach combines fundamental analysis with risk analytics to best execute the hedge path
within the tolerance limits set out and guaranteed within the strategy.
The desk develops a structured approach to hedging based around an
average hedge path which is determined by hedging window and the
deadline to become fully hedged
The longer the hedging window the greater opportunity to ensure that a
contracts market average can be achieved. Statistically speaking you
increase the sample size to achieve a more reliable mean
Depending on your business requirements you may require achieved
commodity costs in advance of the actual commodity delivery and therefore
there is flexibility to bring forward the hedging deadline
A degree of tolerance is beneficial in order to provide the flexibility to
acceralate or decelerate hedging in order to take advantage of bullish or
bearish runs, respectively
Average Hedge Path
Example hedge profile
Strategies are loaded into our fully supported Oracle position management system.
Configured alongside budget and daily VaR reporting. The customer and the Optimisation Desk receive daily position
emails, VaR and P&L reports alongside market updates and analysis.
This flexibility to deviate long/short against an average profile has helped import customers take full advantage of the
recent bearish trends through 2015 while saving the bacon for export customers given their long hedge profile and ability

Hedging Strategy – Risk Metrics
P&L measurement typically includes
… analysing changes in portfolio value due to movements in the forward curve
… but could include performance vs. market average or budget, price quality vs. spread
Value at Risk measures the potential loss in portfolio value
… at a user-configured probability (usually 95th percentile = 1/20 worst case)
… using observed market volatility
… and random sampling of potential prices
Return on risk adjusted capital compares P&L to VaR enabling us to assess
performance against risked capital
… calculate potential losses (anything to the left of the 50th percentile) up to the 95th
… work out the difference between P50 and P95 (the amount of £ risked that results in a
… and dividing P&L by the risked capital - typical levels are ~20%

Is +£10k P&L risking £100k better than +£5k risking £20k?
