2019 GhIE ANNUAL CONFERENCE Perspectives on The Future of the Energy Sector Ing. Dr. Nii Darko Asante Director, Technical Regulation Energy Commission

2 Overview Power Sector Gas Sector Where Are we Going?
Supply Demand Balance Outlook for Capacity Additions Disruptive Technology Gas Sector Outlook for Gas Use Where Are we Going?

3 Power Sector Supply Demand Balance

4 Over Capacity in Power Sector
There is over-capacity of generation, and there is no need for additional thermal generation till mid 2020s Net dependable capacity is about 4,000 MW, and will increase to over 4,600 MW by the end of 2019 with addition of about 700 MW of capacity currently under construction Current recorded peak demand is 2,691 MW, and is expected to grow to about 3,100 MW by 2022. After including a 20% reserve margin on top of the peak demand, there is significant excess capacity until the mid-2020s. Even under an unlikely high demand scenario, there will be significant excess capacity until the middle of the next decade.

7 Power Sector Outlook for Capacity Additions

8 Additional Generation Capacity
Many conventional and renewable Power Purchase Agreements already signed by ECG Some attempt to delay and/or cancel some of them Ghana has some commitments on Climate Change Mitigation No major impact on build plan Costs of Renewables (Solar) continuing to drop Solar may become competitive even with excess generation capacity Will however need to consume contracted gas (more on this later)

9 Transmission Improvements
Additional transmission builds are necessary over time to support new local generation capacity, and the need to improve grid stability and reliability, particularly in the Middle Belt and NEDCO regions. Transmission builds lower the overall system cost and allows for greater export opportunities. Reliability improves upon completion of current transmission projects including the 330kV Aboadze-Prestea-Kumasi-Tamale-Bolga line— Integrating variable RE capacity up to 10-15% of total system capacity improves reliability of supply in the northern part of the country during off-peak hours, and reduces system losses.

11 Power Sector Disruptive Technology

12 Distributed Generation
What is it? Small grid-connected generation (mainly solar) that is located within the distribution network (sometimes on customer premises) What does it do? Lowers cost of supply to customer What is the problem? Avoids centralised planning process (risk of stranded assets), lower cost of supply can undermine established economics of power generation & supply. Things will need to change!

13 A few years ago we were trying to reduce demand!!!
Electric Vehicles Introduction and Promotion of Electric Vehicles Private vehicles and/or Electric buses for public transport Utilise redundant power generation capacity Replace Oil Imports with Increased Power Consumption Would Contribute to Climate Change Mitigation A few years ago we were trying to reduce demand!!!

14 Gas Sector Supply Demand Balance

15 Excess Supply of Gas With completion of OCTP Sankofa project, there is an oversupply of gas, and this may increase to about 550 MMscfd with introduction of LNG from 2020 onwards, and create a huge annual financial burden. On a regional basis, oversupply will be in the Western region, which shall require transfer of gas to East through the WAGP. As usage volumes increase in the East (Tema), there is an economic justification of building an onshore gas pipeline between Tema and Takoradi.

17 Gas Sector Outlook for Gas Use

18 Outlook for Gas Use Short-term actions: Medium to long-term actions
Reduce OCTP take-or-pay volumes. Delay development of non-associated gas fields. Delay LNG development in both Tema and Takoradi. Medium to long-term actions Stimulate economically viable (high-value) non-power use of gas (e.g. CNG for transport).

19 So where are we going…?

20 Heaven knows where we are going…
Upward pressure on pricing Redundant Capacity of gas and electricity Locked into expensive supplies of gas and electricity Stranded distribution and transmission assets Private distribution pushing up prices by bringing all costs into open Pointers to lower energy prices Increased consumption due to economic growth wiping out excess Competitive procurement delivering lower energy supply costs Innovation and Technology driving down prices Efficiency gains from private distribution bringing down costs

21 We know we will! THANK YOU.
