The role of local government in the transition from fossil fuel to renewable energy

Life After Coal: Environmental Rights Seminar, 2016

Status Quo

Cities Mitigation Study

Concentrated

Largely fossil fuels

“Dirty” electricity

Intensive

Energy and emissions by sector

• Energy largely transport
• Emissions largely built environment (residential, commercial,

industrial)

Inequality

Inequality

Municipal response

How can municipalities influence energy use?

• Building regulations
• By-laws, standards, codes
• Urban layout
• Transport planning (parking requirements,

BRT, etc.)

• Procurement policies
• Budget allocations
• Air quality control measures
• Tax incentives

How can municipalities influence energy use?

• Electricity distribution
• 52% of customers
• 12 largest municipalities account for 80% of

municipal distribution

• Electrification / energy service provision

(SWHs, etc.)

• Regulator / procurer of embedded

renewable energy generation

• Awareness (energy efficiency behaviour

campaigns, forums)

• Lead by example (city facilities, rental units,

etc.)

• Electricity generation / IPP large-scale

procurement (potential)

A response story / timeline

• DATA: a new picture, what to manage,

what potential EE and RE

• STRATEGIES: beginning to define local

government role in sustainable energy and institutionalise this

• TARGETS: e.g. EMM, CCT - 10% RE… can drive decisions
• IMPLEMENTATION: community EE (campaigns,

forums), municipal EE, Solar water heating, RE: landfill gas, biogas, rooftop PV, PV array, wheeling, SSEG, Power purchase agreements (?)

Municipal (led or assisted) local RE development

Solar water heater rollout

• Johannesburg: 80 000 low-pressure systems
• EThekwini: 20 000 low-pressure systems; have high-pressure campaign

(Shisa Solar)

• Cape Town: 25 000 high-pressure; 4 500 low-pressure

Landfill gas to electricity

Municipality Size Project Finance / ownership Ekurhuleni 1 MW Simmer and Jack Municipality developed and owned; O&M contract outsourced; plans to expand to

• ther sites

EThekwini 7.5 MW Bisasar and Marion Hill Municipality developed and owned; O&M contract outsourced Johannesburg 11 MW (current) 18.6 MW (planned) 2 landfill sites (current) 5 landfill sites (planned) Private developer; profit-sharing with CoJ via REIPPP; BOOT (Build, Own, Operate and Transfer) More information: www.cityenergy.org.za

Wastewater biogas to energy

• City of Johannesburg: 1MW

(Diepsloot, northern works); municipal developed and owned, with O&M contract

• Opportunities: improved sludge

management

• Challenges: generation dependent
• n ‘down line’ water management

(city function) – no control over this and thus complex contracting (optimising performance, mitigating risk of contracting company)

More information: www.cityenergy.org.za

Municipal rooftop PV

• EThekwini Water and Sanitation

(Customer Service Building) = 45kW

• Cape Town: 167kW March 2015;

additional 90kW planned by end 2015 (various locations)

3rd Party Wheeling

• Nelson Mandela Bay: Wheeling framework –

up to 10% of local demand from privately traded RE energy (80% must be local).

• Tshwane: Electricity generated from biogas on

an on-site cattle farm wheeled through Eskom and Tshwane’s grids to a private user.

• Opportunities: stimulate local renewable

industry,

• Challenges: must unbundle tariff and

establish accurate cost of supply; administrative complexity/burden; Regulatory rules on network charges for 3rd Party transportation of energy (wheeling) – still under development (municipal concerns relating to risk)

Small-scale embedded generation

• Cape Town only NERSA approved

tariffs: September 2014: Black River parkway first ‘official’ – 1.2MW

• EThekwini solar mapping tool
• Johannesburg Parkhurst ‘off-

grid’ project

Disruptive forces

The imperative of climate change

• NASA: each month in 2016 was the warmest respective month

globally in the modern temperature record, which dates to 1880. This trend suggests 2016 will surpass 2015 as the hottest year on record.

The future…? And challenges

Business as Usual untenable

What happens if transport shifts to electricity?

Municipality as off-taker: IPP procurement ?

Unclear policy hurts RE economy

• SWH: rebate → national programme → on hold
• SEGG tariffs: NERSA stating Cape Town and Drakenstein were “pilots”

→ only recently allowed other municipalities to institute SSEG tariffs

• REIPPPP uncertainty: decision by Eskom board to discontinue the

signing-on of any PPAs → Presidency Statement that REIPPP is policy and won’t be halted

New approaches

• Some cities embracing: rethinking new role as energy service

providers, e.g. smarter management of load (supply vs. demand). Basket of measures: dispatchable load (gas, PV), EE, etc. Combination rather than one big supplier.

• Proposed thinking: not revenue that matters, but margins. As long as

costs go down, revenue can go down. Be more efficient, e.g. meet peak demand differently (rather than incurring loss). Offering storage / grid (grid manager) rather than distributor. Will take time.
