Where We are Today – South Africa
• Grid parity reached for grid tied solar systems 3 years ago
• Grid parity being reached at most locations for solar systems with storage
Worldwide sum of direct solar irradiance
Solar Irradiation
IRP Draft 2018
• Solar PV Allocation:
• 1MW – 10MW = 200MW p.a.
• Anticipate cap to be increased, and regulations changed.
• Licensing process and rules unclear
• No limitation for <1MW
• Currently no clear registration process (admin fees)
• Nuclear Disappeared
Extract IRP
• 34,000MW of coal, representing 46% of installed capacity.
• 11,930MW of gas, or 16% of installed capacity.
• 11,442MW of wind, or 15% of installed capacity.
• 7,958MW of photovoltaic, or 10% (PV, or solar).
• 4,696MW of hydropower, or 6% of installed capacity.
The balance will consist of pump storage (4%), concentrated solar power
(1%) and nuclear power (2.5%)
Current Application Framework
• Client approaches us for solution eg. Tender
• We approach client
• Info gathering and feasibility (Bills, consumption data, space for
installation and existing network)
• Quotation and acceptance.
• Contracts engineering application to Grid Operator
• Acceptance and signatures.
• Project realisation.
• Commissioning and synchronisation.
• Grid operators testing and approvals
• Training and handover to client.
Case Study – Mitchells Plain Shoprite

where we installed a
211kWp grid-tied solar
PV solution
Regulatory lessons
learnt COCT
Case Study – Spiros Mica
Spiro's Mica Hardware where we installed a 99kWp grid-tied solar PV solution in Stellenbosch
We Can Do This Better!
Most issues we experienced have been where there is an absence of
policy, or where Munics have been slow to respond even when policies
have been followed.
We have a successful history of building large systems in line with Munics.
As long as a Professional Engineer has signed-off on the project the
Munics should not be concerned about the systems.

South African Position
Escalating electricity costs for consumers:
• 2018/2019 Eskom increase of 5,23% in “allowable revenue”
• 1st Regulatory Clearing Account applications approved @4,41% increase
• 2nd Regulatory Clearing Account applications approved for R3.86bn for
2017/2018, Nersa will announce further details soon
• On top of the 4.41% RCA hike, Nersa has approved electricity hikes of
9,41%, 8,1% and 5,2% for the next three financial years
• Excludes annual Municipal increases
• These combined increases could push up electricity prices by as
much as 40%
Generation costs for Eskom:
• OCGT cost of operation R4,50 to R5,50 kWh
• Drop in volume of kWh sold by Eskom – year end March 2018 Eskom
experienced its lowest annual electricity sales since 2003
• Eskom announced the cost to fix “design defects” at their new Medupi and
Kusile power plants could be as high as R8bn

Grid parity is already a reality with
battery storage!
Case Study – Residential
• Solution cost (per kWh):
• Pinnacle Point
• 15kWp Grid Interactive R1,60
• Grid-Tied R0,64
• Utility tariff (per kWh) is currently
R1,71
• Ocean Ridge
• 9kWp Grid Interactive – R2,08
Case Study – Clearwater Mall
Unlocking Grid Capacity
• CWM – could not expand
mall due to municipal supply
shortage
• Two aspects:
• Air Conditioning Load
match
• Tropical Cooling Effect
• Result:
• Mall could add GLA
• >Rates & Taxes
• >Night-time consumption

Take Aways
• Storage is much more than “batteries”
• Mixture of technologies required
• Moving to a Decentralised System
• Choice of Tech – Cost / Resource driven
• Demand Response is also “storage”
• Fuel in your car is in “storage” – why not use it!
• “Disruption is defined by those that are slow to change, other see it
as opportunity”
