Revenue

SourcesDescription of revenues and GRID’s participation In the context of GRID:

Trading

- Merchant

income

Routes to market:

▪ National Grid’s Balancing Mechanism - capacity is tendered

▪ Wholesale Market - intraday and day-ahead trading

Market size

▪ Ranges from 20-50GW depending on demand

▪ GRID uses four different “asset optimisers”

▪ Asset optimisers use algorithms to continually assess whether

more can be earned from trading or frequency response.

Increasingly, both can be carried out simultaneously

▪ Trading is inherently profitable due to fundamental market

volatility

Frequency

Response

- Short term

contracts

Frequency Response services procured by National Grid:

▪ Dynamic Containment (DC) - daily contracts

▪ Firm Frequency Response (FFR) - monthly contracts

▪ Enhanced Frequency Response (EFR) - 4-year contracts (exp. 2022)

Market size

▪ c.1500MW today, rising to c.3000MW (est.) in the next 2-3 years

▪ Most of GRID’s projects were in EFR (120MW) or DC in 2020

▪ National Grid uses frequency response to eliminate

instantaneous, minor imbalances in supply and demand

Capacity

Mechanism

- Long-term

contracts

Contract types:

T-4 contracts are awarded via auction c.4 years ahead

Durations are:

▪ 15 years and index-linked if awarded prior to commissioning

▪ 1 year for all other contracts

T-1 contracts are awarded via auction c.1 year ahead

▪ GRID has 15-year contracts starting in October 2019, 2020,

2021 and 2023

▪ Trading and Frequency Response are the two largest source of revenue today with potential for

new revenues in future

▪ Frequency Response dominated revenues in 2020

▪ Trading is expected to dominate revenues longer term, as volatility increases due to rising renewable

generation and less gas-fired generation

GRID is differentiating itself in the market:

Scale:

▪ Largest operator in the market by a factor of at least 2x1

Market leadership:

▪ First and only operator to enter all new services offered by

National Grid in 2020 at their start, including

‒ Dynamic Containment (launched October 2020)

‒ Optional Downward Flexibility Management (ODFM -

launched April 2020)

‒ BM Reserve trials (in May, July and September 2020)2

Operational uptime:

▪ Frequency Response availability of 98.8% for the year as

sites continue to deliver against requirements1

Quality and resilience:

▪ Larger batteries than most competitors (>1hr average

duration across the portfolio)1

▪ Lower degradation on batteries than modelled due to lighter

load from Frequency Response1

OPERATIONAL HIGHLIGHTS

98.8%

Uptime

GRID delivered strongly against

Frequency Response contracts with

98.8% availability in 2020.

In Dynamic Containment 99.7% revenue

capture achieved during Q4 2020.

63%

DC market share

Since launch in October 2020, GRID

has dominated this market. Having

been the only entrant at launch, it had

a 63% share of the market as at

31 December 2020.

97.7%

High average SOH

Lower than expected drop in state of

health reflects the benign usage from

frequency services, further helped by

large average battery sizes. DC, in

particular, has involved less that one

cycle per day.

The Investment Manager is focused on creating value by maximising the spread between cost of

capital and profitability of projects to make GRID the most competitive operator of Battery Energy

Storage Systems.

Lowering the cost of capital

▪ Equity cost of capital:

‒ Strong execution can drive the NAV and equity valuation which drives the marginal equity cost of capital down

▪ Debt to drive the Weighted Average Cost of Capital (WACC) down:

‒ A debt process underway whereby even modest gearing could meaningfully reduce the WACC

‒ Debt also reduces cash drag (i.e. the cost of capital which creates a drag on returns prior to deployment)

Improving project profitability

▪ New projects:

‒ The cost of acquiring new projects is declining as a result of the industry’s falling cost curve, our contracting

methodology and procurement advantage

▪ Existing projects:

‒ Driving best-in-class optimisation

‒ Reducing costs across the board

DRIVING PROFITABILITY & COMPETITIVENESS

▪ GRID has a strong track record of using its internal resources and trading partners to optimise

revenues and outperform competitors.

▪ In Q1 2021 GRID achieved 19%1 more revenue than benchmark DC performance through effective

optimisation between revenue streams and data analysis across the team and trading partners.

→ GRID is set to begin construction on 275MW of projects fully committing all

uninvested funds - operational in Q1 20221 resulting in operating capacity of

700MW

→ 527MW of additional exclusive pipeline which will be built subject to further

financing

→ Potential new debt facility would reduce the cost of capital and therefore the

hurdle for paying dividends from operating earnings

→ Strong performance expected from the portfolio in 2021, capitalising on

favourable Frequency Response prices and capturing increasing upside

volatility during periods of high demand1

→ Full coverage of the 7.0p dividend expected in 2021 despite cash drag during

the construction of the current pipeline

→ Recent acquisitions and future pipeline expected to be accretive to NAV

The UK electricity market has changed dramatically in the

last decade (see chart 1). Coal has left the mix and

renewable penetration is growing rapidly.

This has driven a huge change in how power is generated

intraday as shown in charts 2 and 3.

A few key changes will take place that will drive the need

for batteries significantly.

i) More demand for electricity supplied increasingly by

renewables

ii) Less baseload generation, and in particular gas-fired

generation which to date has been National Grid’s

key source of flexibility

iii) In addition, Ofgem has driven regulatory changes

that level the playing field for batteries

iv) National Grid has implemented changes in the

Control Room that make batteries more useful to

them which unlocks the potential to stop using

flexible gas CCGTs

So far there are around 1.2GW of batteries installed in the

UK with GRID owning 425MW of them. This compares

with 47.9GW of renewables1.

DEPICTION OF GB ELECTRICITY SYSTEM

The Transmission System

operates as a backbone

network carrying electricity

over long distances at

extremely high voltages

14 regional Distribution

Networks are connected to

the Transmission System

carrying electricity to the

final consumers

Energy Storage Systems

can import and export to

address system instabilities

and supply-demand

imbalances

Electricity Generation has

migrated from being

“baseload plus peaking” to

“intermittent and volatile”

Energy Storage Systems

can operate locally through

collocation and / or

“private wire” arrangements

Energy Storage is a “relief valve” for system instabilities and, increasingly, for the growing supply-demand imbalances

caused by the growth in renewable generation

Page 24: Gresham House Energy Storage Fund plc

The chart on the right shows low carbon generation (Solar, Wind, Biomass and Nuclear) as a percentage of demand. The growth in highly intermittent generation is

mostly a function of offshore wind commissioning and this is set to continue with c.15GW in new offshore wind projects set to commission by the mid 2020s1.

The widening extremes in generation highlight the need for batteries. These extremes manifest in increasing volatility as shown in the chart below. By 2023, the

need is for in excess of 10GW according to Gresham House.

In addition to volatility-driven trading opportunities, the market has so far been driven by frequency response contracted by National Grid to balance small, ever-

present deviations in supply and demand which manifest as frequency deviations around 50Hz to which batteries respond dynamically (i.e. in real time and

proportionately to the level of deviation).

▪ Investment Manager awarded highest score (A+PRI) for

infrastructure strategies reinforcing GRID's strong

ESG credentials

▪ In 2019, the Committee on Climate Change recommended

a net zero emissions target for 2050 for the UK. Current

target is for an 80% reduction1

▪ Renewable electricity penetration rose from 9.6% in 2011 to

46.4% in H1 2020 and is expected to rise to c.53% in 20232

▪ UK wind energy generation was curtailed on 275 days in

2020, losing energy which could have powered over a

million homes for a whole year

▪ Energy storage enables cost effective transition to higher

penetration of renewables by avoiding curtailment whilst

helping stabilise the energy network that now relies more

than every on intermittent renewable power

▪ Est. 63,000 tonnes of CO2 emissions avoided versus gas-

fired power through our portfolio in 2020, over 82,000

tonnes since IPO3
