EPR waste reporting – ‘Producer Pays’ Transition• Extended Producer Responsibility for Packaging (28 February 2022)
Will see the full cost of gathering and collecting household waste transfer from thetaxpayer/consumer to the producers under the The Packaging Waste (Data Reporting)(England) Regulations 2023.
Applies to;• An individual business, subsidiary or group (but not a charity) with an annual turnover of£1 million or more (based on the most recent annual accounts for the company) which
was responsible for more than 25 tonnes of packaging in 2022.
Requires the collection of additional data on household waste generated and brings theintroduction of modulated fees (the payments required by eligible organisations) which will
increase/decrease depending upon the recyclability of the packaging.

Plastic Packaging updates• Plastic Packaging Tax Regulations (1st April 2022)
Plastic packaging tax on packaging manufactured in, or imported into the UK, that does notcontain at least 30% recycled plastic, coming into force since the 1st April 2022.
Applies to;• UK manufacturers of plastic packaging, importers of plastic packaging, and the businesscustomers of manufacturers and importers of plastic packaging who manufacture orimport more than 10 tonnes of packaging within a 1-year period
Requires all eligible organisations to pay packaging tax. This is currently charged at a rate of£200 per tonne of waste.

For more information on list of EU laws intended to be revoked see; Schedule of retained EU
law - GOV.UK (www.gov.uk)

Net Zero (SBTI) – Urgent need for Beyond Value
Chain Mitigation aka Offsetting• Beyond Value Chain Mitigation meansoffsetting• Actions that reduce global emissions –typically by decarbonising grids (solar,windpower etc)
• SBTI clear that without this we not meet globaltargets• Dates from 13 September 2022.
• Do this as part of your net zero programme –won’t be able to ‘net it off’ your footprint but
without it, your target may not be reachable• SBTI is not ‘anti reductions offsetting’

Essential - Science Based Targets

Water Companies Continue to Get High Fines…
• Anglian Water fined £2.65 million after allowing millions of litres of untreatedsewage to overflow into the North Sea.
– An investigation in 2018 found that the discharges into the North Sea between June and July 2018
– Approx 7,500,000 litres of raw sewage discharged into North Sea– Record fine for the area.

• South West Water fined £2.1 million for a series of offences which resulted inenvironmental damage and pollution of rivers and a lake across both Devon andCornwall– Fined for various (13) pollution incidents across Devon and Cornwall area over a period of fouryears.
– One discharge lasted for over 35 hours and samples taken from a stream at the beach showed E.
coli levels to be 2,000 times higher than the level that would be classified as poor.
– £2.1 million fine– £280,000 in costs– £170 victim surcharge• The Government has also published a Consultation which aims to strengthen theabilities of the Environment Agency to issue monetary penalties for environmental
offences in England, and to raise the cap for such penalties.

Why should I invest in solar PV and batteries(Part 2)?
North Hants Sustainable Business Network
18th May 2023
Martin Heath
07771 805000
Martin.heath@bes.coopA reminder of what we concluded in Part 1–––––Find a good roof (orientation, pitch, age, material).
Check how and when you use electricity (match with PV generation).
Survey internal electrical distribution system (is it good enough).
Optimise size of solar PV against electricity use patterns.
Work out the “hard” business case (yields, self-use, revenues,savings and costs)– Work out the “softer” benefits (Emissions reductions, benefits toemployees, wider community, suppliers). A powerful and visible
statement– The value is in the design and optimisation not in the installation– THE POTENTIAL BENEFITS ARE HUGE

So what do we want to cover today?
So I now have decided to get PV (or I already have it), should I invest in batteries as well?
Three areas– Types of battery– How should I use them
– A case study
Take aways– It’s much more complex than solar PV alone– Lots of types of technology– Need to balance load, generation and consumption– Monitoring and control are vital– Batteries work; but not always– Understand why you want batteries– There are 2 modes of use – winter and summer
But today is focussing on storing (time shifting) electricity generation and use in small scalebatteries.

Who are we? Founded in 2012

What have we done so far?

Why do I need a battery?
1.
2.
3.
4.

To store surplus generated electricity for later use (4-8 hour time shift)
To capture cheap overnight electricity to use the following day (12-18 hour time shift)
To provide back-up during outages
To provide grid services – peak shaving, grid stability, short term operating reserve, fast frequency
response……
Today is about 1,2 and 3 only. Grid services are a complex area and only really suitable for grid scale
operations eg > 0.5MW, 0.5MWh5kW, 14kWh NOT 2MW, 4MWh

Types of battery
AC or DC Coupled or hybrid

Chemistry – Many types eg
Salt water flow
Lead-Acid
Lithium Ion
Lithium Iron Phosphate
All vary in terms of energy density,
storage times, charge and discharge
rates, costs, lifetime
LiFePO4 is, currently, the favoured
chemistry for small to mid-scale
applications

What do they look like?

14.4 kWh/6kW

10.66kWh/4kW

13.5kWh/5kW

What do they look like?
2.4 meters

1.1 meters13.5kWh/5kW

100kWh/50kW

But all are scalable eg
4 x 13.5kWh Tesla powerwalls
20 x 100kW kStar

Getting battery sizing right is a balancing act of load,
generation and charge rate. Monitoring and control is vital.

Points to note
1.

4.
5.

Inverter size determines charge rate
Battery size determines total energy stored (and charge rate)
Trick is to fill the battery in 4 hours or less overnight
Inverter and battery size determines discharge rate
Size the battery/inverter for expected consumption (kWh) and power (kW)during the evening peak so it is empty by start of next charging period

What makes a good investment?

Six key factors:
Install Cost (£/kWh and £/kW)
On-site use (%) and load patterns
Size in terms of capacity (kWh) and charge/discharge rate (kW)Electricity Price (£/kWh) – how much can I save; at what price can I buy
Depth of discharge/usable capacity
Zero VAT if installed with solar PV
A Case study
SME or large home
10kW Solar PV (24 degrees from south, 35 degrees pitch)
11.6kWh battery (10.4kWh usable)
7.5kW hybrid inverter

6,000 kWh a year consumption
9,000 kWh a year generation
